Reliable Replacement Seals
These washer yoke seals are great. This is my second kit, and after using them for a while, I can say they have the perfect size and they work just as well as the ones that came with my tank. Good product, I definitely recommend them.

WELL MADE
Took awhile to get these, but I'm glad I did. These look like good quality washers. Green in color with felt-like texture. Chemical proof and very durable. Not sure if waterproof.
They came in there own sealed bag, so you can store these away without them getting wet or dirty. I could not find these at other hardware stores anywhere. So glad for Amazon! A coworker at JPL mentioned these to me. I'm guessing they use them too. I ordered another set after I got these.
I would definitely buy these again and like I said above, I did.

Worth the price, work well
I'm reviewing two versions of this item - both are the same with the exception of the number of washers in the package.
The washers/o-rings are exactly what you need when putting an O2 regulator onto the yoke of a portable cylinder. Much better than the standard plastic o-rings that come with the cylinders after refill - they help get and keep a good seal, and are much more forgiving than other washers.
For the price, they are worth it. Seriously. You get what you pay for. These are worth it.

Definitely premium
These are of fantastic quality. A great sealing washer with a durable rubber material (viton) that is obviously better quality than standard rubber washers. Not only does the material seem thicker and more dense, but it’s formed more uniform than standard seals.
I do believe the increased cost is appropriate because these will last far longer than standard rubber washers. These are great!

Brass! Viton! - KOKAND Oxygen Regulator Yoke Washer Seals
KOKAND Oxygen Regulator Yoke Washer Seals
In my limited experience, these are the nicest oxygen regulator yoke washer seals I have ever seen. I like they are made from brass with genuine high-performance Viton. There are 10 in the package. Latex and BPA free. Note: made in China.
Recommended - verify if this is the correct item for your needs.

Heavy Duty Brass and Viton Seals
These washer seals are made of solid brass backed with Viton rubber for sealing high pressure oxygen connections. Brass gives durability and resistance to deformation while Viton provides a good seal under pressure and exposure to chemicals. The seals are designed for CGA-870 systems commonly used with medical oxygen regulators.
The combination aims to prevent leaks effectively and last longer than standard rubber washers. The pack of ten gives you backups for maintenance or multiple setups. For a pressure seal component, this feels like a strong choice for safety and reliability.

DEFINITELY keep a spare pack on hand - seem superior to others
These are an absolute must have for anyone who is dependent on supplemental oxygen. This tiny seal can come off or leak changing tanks leaving you with useless and unusable oxygen in a life saving situation. I am very pleased with the quality and quality of these. In fact I purchased a key ring and put several on my oxygen handle and taped one to each bottle of oxygen for an emergency. Brass is strong and doesn’t rust, the rubber like seal is resistant to most everything. These are very inexpensive and an absolute essential. Can’t find a better value for your money. One I replaced using this one has a literally perfect seal to it now, I feel much safer and confident having these and would definitely recommend this brand with the brass lip and sealing membrane over other less reliable ones. Definitely a great value for the money.

good quality, plenty of spares
I sometimes wonder how useful these reviews are... Its going to be months before I know if these are awesome, or junk; and if I wait until I know for sure, I will forget to write this. If they are junk, I'll come back and edit the review, but I don't think so.
Using Viton instead of rubber is going to make these longer lasting and more stable, which is important for me, since my tank rides around in the car with me (especially compared to the rubber/plastic ones that came with the regulator)
These should each last at least 6 months, so the pack is basically a lifetime supply.
In general, don't cheap out by getting rubber seals. You might be able to find less expensive Viton seals, but if you need them, just buy them; both the peace of mind that you have spares, and the good materials make them worth it.

Fits my regulator perfectly!
These fit my regulator perfectly. I didn’t realize these things should periodically be replaced. But when I took the old one out, I could see it had not been replaced in a LONG time. I feel better knowing there’s a good, tight fit now.
Great to have a supply of these.
