SP Medical Oxygen Regulator Brass Yoke Washer Seals - Pack of 25

These work great with both of my portable oxygen regulators. I doubt I'll ever need the whole package of 25, but it's nice having a couple of spares hanging on the same cord as my oxygen wrench. Would buy again if I needed them.

It all good - I use a D tank in a backpack and have to pulse regulator - which more "sensitive" for some reason so I am using there more often - but they do the job.

Wanted to give these pretty Blue ones a good workout before saying anything.Some black ones melt, and makes a mess on the valve and regulator.Other black ones last a while but not as long as I would like.Got these pretty blue ones from Club DME and I like them. I swap out twobackpack tanks at work every day and have not had a blue one go bad yet aftertwo months now where I was going thru at least 1 black one every week.Club DME did great with delivery and I hope they continue with these blue ones.They work, that's the point, and it's nice to have a few extra at hand.Update:I decided to order more of these so I would have them and there not the Blueones as before. Yea, I know, the picture shows the black ones but it's thesame picture when I received the blue ones. These look fine, as they should,but if I have problems with them melting I will add another update. Will stickone of these in my day use tank today so will know soon if they melt. (9/24/13)Little more info:I am finding out over the course of time that the blue seals are a bit harderthen the black ones and if you don't crank on the T-handle they will leak a bit.If I grab a tank by the regulator to carry it it will start hissing which is nota good thing. The group of black ones that I received are working out fine, nonehave melted like some others I had, and I refill these tanks sometimes 3 times aday so they get a lot of use.As I see it, blue ones are good short term, black ones good over time and use, butyou might get some bad ones that turn to mush.Good thing there not that expensive. (7/27/14)PS>don't spend a lot of money on a couple of these from a supply store.Buy the bulk when they have a good price, that way you have them. If there notgood ones then look for a different seller, but always have some on hand. I keepthem in my cars and at home and at work and in my wallet. If your out and it goesbad, you best have one ready to replace it with. But I am sure you know this already.(hope this info helps)

Without these little seals there is no oxygen regulators are built around these discs as a safety devise so if the tanks pressure gets to hi it can be released thru this seal instead of exploding but. No seal no oxygen regulator will not work without one of these

These brass and rubber seals are a must have for oxygen users. They last forever, and they are much much more reliable. They also stay on the regulator , while the plastic ones fall off if you are not caareful while changing tanks.

ok

The seals are a perfect fit for my regulators, what more can i say

Bought for my father's oxygen regulator. The on gave him one and it was a cheap leaking plastic one. These hold up for a long time and mustple uses. Great investment toward a hassle and leak free connection.
