Buna-N O-Ring Kit, 70A Durometer, 382 Pieces, 30 Sizes (Color May Vary)

Q: could these be used in transmissions

Nitrile rubber, also known as NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. This is an all-around automotive material resistant to oil, petrol, mineral (automatic transmission) oil, water and alcohol. It has a temperature limit of 225 F. It is not good for acids and many non-pertroleum solvents. Transmission gaskets usually require a specific o-ring material as noted by manufacturer. Search for a compatibility chart on the internet for more specific information.

Q: What are dash sizes? Why not just state the actual size in mm? They're metric o-rings, right?

not sure what the dash is here. but these are not simply metric sizes. number 325 is not 325 millimeters. I am very happy with them.

Q: Suitable for automotive repair?

Suh, Yes, can use in automotive applications. I have used them twice on my older Ford Mustang, working just fine. Have also used on hydraulics on my tractor/lawn mower, andwater hoses. Kind regards, Charles

Q: are these O rings compatible with Propane such as would be used on BBQ or travel trailer heating?

Yes, I have replaced all the "O" rings on my RV, because of the age with rings from this kit. Two years and no problems !
