But the main description says they are for plumbing use. Can someone please explain? **Q: Does this work for air sealing? trying to seal an air gap between an air motor and a hopper unit in my airsoft gun.** A: Certainly worth trying; this is a handy kit I purchased and my husband has dipped in to it on several occasions. These are round, but if it can be compressed enough to seal off your area, and as there are no caustic fluids are involved (ie, like an AC unit with the newer freon), it should be fine. You just have to find the right fit. Hope it works for you. **Q: need to buy 150 1/ 4 id 3/8 od 1/16 thick 0-ring** A: This is a metric set. You might find something close but not exact n this set. Suggest you look specifically for the O ring size and material makeup that you need. **Q: Operating temperature for car fuel injector is 230C healthy and 320C for failing injectors, so this o-rings can't be used right?** A: I wouldn't ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well, they’re O-rings that are oil and gas resistance so far so good *by R***E on November 8, 2025* Well, it is what it is they’re O-rings.

Low-profile case box. Not for paintball repair. *by J***T on April 23, 2025* I really like gow flat and low profile the o-rings container is! Can store in small space or take in bag. Bought it to repair used paintball guns I bought for cheap. Fixed one crucial air bolt assembly part requiring 3 o-rings.
