Ever Ready First Aid Oxygen Regulator Brass Yoke Washer Seals - Pack of 25

BEST TANK VALVE WASHERS! KEEP EXTRAS ON KEY RING!

Works perfect for my oxygen pulse meter

Great seal on regulator. Lasts lone time between changes.

These fit my regulators perfectly and no more leaks! I used to get my replacements from my home health 02 supply company that provided my regulators too and they would always leak. If not right away then at least within the first week of usage and they would just give me more. I replaced 3 of them with these new ones and not a single leak! I left all of them on/opened giving any of them a chance to fail and have not lost a drop of oxygen that I can notice. Time will tell how long they last but they pass in my book… They appear to be top high quality O rings made with quality materials. They all appear the same, no creases or dimples or any kind of “machine misprint” like they didn’t run through the manufacturer process correctly or anything. I can’t tell one apart from any of the others in the entire pack. I’ll be recommending these to my med supply company and if you buy your own I’d suggest definitely checking these out. There’s nothing worse than reaching for a empty can of air when a breathing attack kicks in and it looks like my old leaking problem is solved.

These oxygen yoke o-rings fit medical oxygen tanks. I have had no leaks with these o-rings. I expect that these will work for sometime. This is a good value.
