Review: Fake product - This is not orignal prouduct from GTM its copy or too much costly from orignal
Review: Great O Ring Assortment - 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 !

### ⭐⭐⭐⭐⭐ Great set for a good price
*by M***E on 29 June 2020*

I needed to fix my 20 year old power washer. My father in law bought if for me from some discount store years ago and it’s some kind of knock off so I couldn’t find any specs for it. Bought this set and 5 o-rings later I’m in business again!
