Yoke Washer - O Ring Brass/viton for use with Oxygen Regulators, 5 Pack

The brass/viton washer actually works - unlike some plastic washers my oxygen company used to provide. Eventually the washer will wear out, which is why a 5 pack is a good idea. Though I seem to get at least a month out of a single washer, I also try to carry a spare with me.

Fits regulator works well

These literally save my life. I could not breathe without them.

Bought this pack nearly a year ago for a replacement of older rings. Very well made. Still using to this day.

I was told by the company that supplies my bottles and regulator that these never go bad. Three days later I changed my regulator and it fell out and disappeared. Luckily I had a spare regulator and could wait for these to be ordered and shipped. This O-ring is an exact match to the original in my extra regulator and fit and worked in the one that I lost the O-ring. I received some of these from my oxygen supplier but it took a week, these came in three days.

Regulator seemed to be leaking, decided to try new O ring seal. Easy to pry-lift out the old, pop on a new one, works like a champ, stays in place.

Plastic Seals were leaking, these are working very well for us.

I mean, they are brass O2 rings. They either work or they don't. These do and I appreciate the 5-pack for home use... a 25+ pack is just overkill.
