Review: Fake product - This is not orignal prouduct from GTM its copy or too much costly from orignal
Review: I liked the fact that it was a variety pack, and it had the size I needed, at a great price. I needed a couple of small O rings for the hose and wand on my pressure washer, and this product work great. The O rings appear to be not very firm but durable, they are a made of 70 durometer Butna rubber, and not as firm as the (90 durometer nitrile rubber). So far no leaks, and would recommend.

## Questions & Answers

**Q: could these be used in transmissions**
A: 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?**
A: 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?**
A: 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?**
A: 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 !
