What a crazy thing I'm over here searching videos about which type of O-rings I should use for this project and there's a guy who dedicates his whole life to them
Thank you for teaching me on how O-rings seals expand. A mechanic suggested I change two small o -rings that connect to my transmission because they might be "swollen" since the metal pieces would not fit after I took them out. And now I understand that the swelling was caused by the transmission oil making contact with the o-rings; 13 years and 89,000 miles worth, creating a seal that not only seals transmission fluid from escaping but inadvertently made it impossible for me to reinsert the two lines back into the transmission.
Dear Jesus, I understand your frustration. I have talked with many technicians, the modern automotive design makes the replacement of a simple O-ring become "Mission Impossible". But I also talked with some auto designer, they have their reason too. For your reference, if you find a way to replace those O-ring, you should look at AEM rubber (known as DuPont VAMAC) have a good resistance on ATF or transmission fluid.
The ID and OD will also increase. Consider the rubber O-ring is a constant volume object, if the swell is "homogenous swell" to entire material, total volume increase 1%(1.01V), ID and OD should increase about 0.3%(take cubic root on 1.01) Use AS-214 as example: ID 24.99 mm, CS 3.53mm, Volume is 1753mm^3 1% Swell Volume to 1771mm^3 Calculated ID is 25.07, CS 3.54mm, OD 32.15mm
Thank you, interesting video! So, I will try soaking my O ring pump gasket in acetone for up to 5 minutes to see if it will increase size so my hand pump tank sprayer will work again more permanently. It sat unused all winter. I stretched it manually but it only fixed it for about half an hour, enough so I could at least fill the tank with pressure. I'm hoping I have good luck. Keep up the good work! 👍
I am an auto mechanic and remember sometimes brake fluid can swell rubber seals. Sometimes / usually it results in bad things. But now i have a home carpet shampooer with a seal that failed. The seal sits on the bottom of the clean water reservoir. I cant find the replacement part so either i buy a new vacuum for $200, or a new water tank for $40-50, or try to think smart and modify this cone shaped seal. I need the part to work maybe 4 times per year for 1 hour each time. Maybe i can try to soak the seal in acetone as you did and hope it dont spill out a half gallon of water. Thank you for your video. But sad to think the part may shrink back after some time.
I do have some cheap tip to make a custom shape gasket for DIY at home. However, it might not be that durable. The acetone swelled FKM rubber eventually will return to it's own shape. Sorry for a very late reply, our company was closed due to global uncertainty. I will make this channel to personally own, it might take me a few months. Thanks for your support :)
Hi, I want to make a Latex in Liquid form with the help of rubber. What is the procedure to dissolve the rubber in Liquid form. Even room temperature is cool.
Thanks for sharing the experiments. I have one question, if you add the saturation acetone solution of VDF rather than acetone, does the rubber O-ring swell?
Unfortunately, molded rubber is very hard to diffuse material into it's body without change its physical property. The more filler or additive you add the stiffer the rubber will be. Thanks you so much~ I really appreciated it. Sorry for a very late reply, our company was closed due to global uncertainty. I will make this channel to personally own, it might take me a few months.

I knew the seals would swell, but, didn't know the "why" behind it all. Thanks!

Thank you Thomas, we will try our best to update more content :)

Excellent explanation of your knowledge on this complex subject. Thank you.
Glad it was helpful!
Thanks for sharing the experiment results. Can you please explain change in ID & OD after O-Ring swelling?
The ID and OD will also increase.

Use AS-214 as example:
ID 24.99 mm, CS 3.53mm, Volume is 1753mm^3
1% Swell Volume to 1771mm^3
Calculated ID is 25.07, CS 3.54mm, OD 32.15mm

@@theo-ringguy6172 hi, do you have the video on how to DIY a gasket seal at home? Couldnt find it, thanks!
Am I OK to use Acetone where O'rings are housed?
Good job mate! Do you have any experiences with fire retardant EPDM?
Too many distractions such as music, noise, sound effects, on this type of topic. Try it without the extras.
We will work on that, thanks!
I thought the squeaker noise was cute but i need the info clearly.
Hi,
I want to make a Latex in Liquid form with the help of rubber.
What is the procedure to dissolve the rubber in Liquid form. Even room temperature is cool.
Is there a solution that can dissolve FKM rubbers?
Yes, Fluorinated Solvent. Such as 3M™ Fluorinert product line.
Thanks for sharing the experiments. I have one question, if you add the saturation acetone solution of VDF rather than acetone, does the rubber O-ring swell?
Did you mean once FKM reaches saturation, will they keep swelling? It just like a sponge, once it reaches saturation it will barely gain any volume.
@@theo-ringguy6172 yes, that is what I mean, thank you for reply.
I want to increase the wieght of rubber band so tell me the best way to increase the wieght of rubber band without losing its strength and elasticity
