RV Propane Quick Connect - High or Low Pressure??
Вставка
- Опубліковано 21 лип 2024
- Today I install an RV Propane quick connect to the outside of my camper to allow using my camper propane tanks for my BBQ grill!
The problem you must overcome is whether to plumb the propane line for High Pressure, or Low Pressure?? This is determined by your grill and whether it has a regulator attached to it. In this video I explain the differences and show why I plumbed my propane quick connect for High Pressure!

Propane tanks can reach up to 250 psi in the summer at very hot temperature.
Also the QCC1 light green is not for high pressure. It is fine for the grill you have but if you where to put a torch on the high pressure quick connect you made the green QCC1 has a shut off valve that will kick in if the pressure rising quickly. Ideally you should get a QCC1 RED with hose attachment that will work for any high pressure appliance you have.
You can also do a pressure test without propane which is safer,
To take it further you could have added a splitter and another regulator for low pressure and have a quick connect for low pressure as well.
You can use 2 regulators as long as the first regulator has higher output pressure there will not be any problems.
There is an attachment you can buy that is 3/4 Inch Pressure Test Kit, 100 PSI, Push to Connect Brass Plumbing Fitting,
You basically attach this fitting to your setup and air compressor and push as much air as you want and then test for leaks. Much safer.
Nice video and informative never the less :)
Ditto, great job. Wow............I bet you have a very nice rig if all your other mods are designed and built like this one !! Thanks for sharing.....
Finally, a video that answered all of the questions I had. Thank you!
Attention to detail in 150%. Awesome.
Excellent video and explanation on the quick connects
I learned something today. Thank you for sharing. Excellent presentation.
Thanks for the video Charles. I'd suggest you also use the rubber plug on the end of you quick connect. You don't want road dust getting into the end of your connection. My trailer came with a factory installed quick connect and the yellow rubber plug. It catches a lot of road debris from my truck's tires. Thanks again :)
Great job Charles as always. Is that hose clamp ok for the HP line? 150 PSI with a hose clamp seems a bit high.
Excellent video! I am dealing with a similar issue myself. Thanks for the info!
Wow, that is so nice and thoughtful. I have learned a lot from your video.
You’re a smart man with some really good ideas
You do really nice work!
Wow, you sure do a very excellent job, maybe too good? On the verge of overkill, and that’s a compliment Charles! Thanks for explaining the pressure differences! 👍🏼☮️
Excellent video. My issue is, my RV came with the propane connection and the BBQ. I bought a Coleman BBQ that use disposable tanks, bought a hose for the quick connection and the 1”-20 but only get a small flame.
The propane quick connect on your RV is most likely low pressure and your grill is high pressure if it uses a disposable canister and a regular.
Awesome video thank you. Great explanation and great work protecting it
You’re a goddamn genius Gump. Thanks, I learned something today!
Excellent presentation, thank you.
Love your attention to detail, but I think I'm just going to keep refilling my 1lb tanks with a refill adapter.
Great job thanks for sharing.
Excellent info. Thank you
I would have made the line low pressure coming out and just put an adapter on the other regulator to take to your neighbor’s campsite, but that’s just me.
Your a Great Teacher
You have opened a can of worms for my RV project . I have ordered a propane only Baja 900 -watt generator to charge my battery's with . I was going to hook it to my quick connect where my out side grill would be connected . The regulator must be inside this unit . That's going to be going through two regulators. Any advice now that you have an understanding of this propane pressure stuff . Thank
One should not use galvanized pipe for gas lines... Should have used black pipe... it's for gas lines..
Bought a little grill assuming I could just plug it in for the quick connect and it would work. Not so. I could tell the pressure was too low. But I had no clue there were high/low pressure grills. Thanks for the lesson. Looks like I need a low pressure grill.
I’m wrestling with a similar problem but the low pressure stuff often is affected by wind so look for something with wind blockage. I’m likely going to add a T at our RV 20lb tank to plumb a high pressure line with high pressure quick disconnect like he did (however less overkill lol) and the rest of the RV system will still be low pressure after the std low pressure regulator on the other side of the T.
Or maybe not. A comment from someone else makes it pretty clear this is unsafe because the propane in liquid form will take up the volume of the line to the quick disconnect. All because the best practice is to have regulators as close to the storage tank as possible.
@@joshhaas2410 yeah, unfortunately I will probably end up springing for a new grill + conversion parts. Just like the RV industry to make something that should be easy, difficult and expensive lol
@@Eric-469 I’m sure you’ll figure out a good solution. I was putting together a line with a T at the main lp tank to go without a regulator to a high pressure disconnect dedicated for a high pressure stove. Well, after pricing all the parts it’s just not a good way to go. Grill plus parts I’d be well over $200 and I learned it’s not safe to have the regulator that far away from the tank with liquid lp in the line. So I’ve decided similar to you at first, to stay on the low pressure side and I’m currently searching for the right low pressure dual burner for my needs. Good luck to ya man!
Great job!
You would be further ahead to just buy another low pressure grill, because now you can't use the switchover regulator between the 2 propane tanks.
Totally overkill and I totally loved it!
I love your ingenuity! However, entrapping the metal conduit (new gas line) with an exterior pipe may result in gas to buildup if there’s ever a leak. You must not have an exterior hose pressured with gas using transport. If anything, you should have made a QC connection on door so you could quickly open tank valve, close the access door and connect grill to QC. When finished, close valve on tank and remove extension hosing.
Becareful!
If 1# tanks are high pressure how can I push in the valve by hand to bleed before refilling?
I’m trying to make a distribution off bigger 20, 30 or 50# tanks to feed several appliances that usually take the small 1# tanks & looking for info to do so.
Can you install the same for my Roadtrek?
Nice job.
My grill came with the regulator on a detachable hose so I can go direct from the low pressure RV connect to my BBQ.
What grill do you have? I’m looking for one just for my low pressure outlet on my RV.
So have you essentially taken one of your propane tanks out of the loop for you automatic changeover regulator Charlie? Both of my tanks are connected to the automatic changeover regulator that controls flow to my TC appliances. My quick disconnect is attached to a separate line that comes off of my propane system just like my appliances do. However when I connect my quick connector to it to use my grill, there is not enough pressure to push the propane through the 12ft hose so it won’t work. I will check that fitting end you show in yours. Seems backwards in your mod to me.
I think the reason you are not getting enough pressure is because you have your QC to your grill after your regulator, and your grill ALSO has a regulator.
You need a rubber grommet in the hole in the floor to protect from cuts and abrasions on that flexible gas line.
Although the finished install inside the propane tank area wasn't shown in the video, I can assure you that the steel pipe came completely thru the floor before the flexible hose attached so abrasion will never be an issue!
Good video I’m having trouble with my inside stove stay lit it will come on for a few seconds then go out I have followed instructions on turn on the propane slow and still have the issue how do I know if I have the right regulator it’s a 2018 Winnibago MD 1790. Can you please help. Would like to chat on phone if possible. Thanks.
Stoves operate off of regulated propane, but stove tops typically have a second regulator at the stove that drops the PSI down from 11 WC to 10 WC inches. If your normal regulator is working, shown by all else working normally, then your second regulator at the stove may be bad. Best wishes!
My DRV came with a quick disconnect on the low pressure side, after the regulator. I would like to connect my Coleman RoadTrip LXE Propane Gas Grill which comes with a detachable regulator. I am able to get the low pressure connector that connects to the grill after the regulator supplied to this grill, or I could remove this connector from the regulator so it can be connected to a compatible low pressure mail connector. My dilema is that I heard that the regulators supplied with this grill may supply a greater low pressure than supplied by the regulators in the trailer and therefore not supply adequate gas for cooking. Are you able to confirm or deny this?
I wonder if using a single braided stainless steel line would be a better option, this would eliminate joints which are potential failure points?
Great idea except they do not sell flexible lines long enough to reach where I wanted to go! Also heard that high pressure lines over 10-15 feet long collect oil in the propane line and require a trap (like in a house) to remove the oil before it fouls the appliances!
Hi Charles, there are a range of braided lines availble on ebay, I bought one 3 metres long (9.8ft) and it has worked perfectly for my setup, just another option for you.
Hi Charles, don't you think you have the high pressure and low pressure quick disconnect mixed up? I went to an RV store and low pressure looks like the high pressure on your diagram.
Did you get this resolved? I think I’m having this issue. My RV has the quick connect with a bar inside but it’s after the regulator so it should be low pressure. I’d love to know what you found out.
@@richardcabrera1583 If you RV has a factory installed quick connect outside (double check your RV dealer) the pressure should be regulated near the tank. I have never seen HP more than a foot from the tank as there is usually a regulator similar to this: www.amazon.com/dp/B08XYH5H6Q?th=1&linkCode=li2&tag=camperfaqs-20&linkId=bcf3d3cd459becbdd51c0606cddf615c&language=en_US&ref_=as_li_ss_il .
The quick connect on my trailer also has the blade style actuator which is labeled as high pressure in the video, but is after the regulator on my RV so it should be low pressure. And now i'm even more confused than before the video.
The quick connect that came from the DRV factory is connected on the low side and is consistent with the one identified as a low pressure connector in this video.
Wow!...I mean...Wow! Way over the top, but you do you.
Great info, thank you! Please invest in an external microphone, will really help us hear you.
Thanks for the tip!
Nice job god bless
Threaded connections use the first third of the threaded area to start the threading, the middle third to make the seal, and the last third for the inspector to see that it’s done properly. You haven’t gotten it nearly tight enough. Once it bounces down the road it will loosen and drain a tank really quick(since it’s unregulated). Yeah, I’m a plumber.
I did not even notice the threads, I was too busy looking at the rubber hose through the metal floor with no grommet!😰8:00
Good catch. Only two turns of the tape Oops.
Charles, You have very informative content in your presentation. PLEASE invest in a wireless mic to make your audio better quality. They are available at very reasonable prices!!!
Helpful information, but the area you recorded in makes listening painful.
With them shoes it ain't going anywhere 😂
There are so many things wrong and unsafe. The reason the storage pressure is high is to keep the propane in liquid state allowing you to store much more propane in your tanks than if it was in a gaseous state. Most, if not all rigs have the regulator and close as possible to the storage units and not allow the HP propane into the distribution system. There are DOT regulations that address this issue. With your design, the propane may still be in liquid form in the piping and the hose upstream of regulator on the grill. Running HP gas (liquid) to the grill will cause oil build up in the line eventually faulting the regulator at the grill. I assume that you are now running liquid propane in the hose, on the ground. Are you protecting this hose from potential external damage (rocks, stepped on, etc.)? Ironic that you are trying to protect the steel pipe with PV.? Also, over time, the galvanizing will flake inside the piping so you need to install a filter before the regulator. Please reconsider to convert to LP hookup, convert the grill by removing the regulator, and just buy a second grill to take to a friends place. Sorry for being such an alarmist.
You maid tons of sense……. Thank you
Thanks for sharing this. Back to the drawing board.
High pressure does not mean there is liquid in the line! If there is liquid in the line, the tank was overfilled or has tipped over while the service valve is open.
