110 Silicone O-Ring, 70A Durometer, Red, 3/8" ID, 9/16" OD, 3/32" Width (Pack of 100)

I got these to replace rubber rings in a polymer clay extruder. These worked like a charm, I am so happy I found them! They have the tight fit that was needed and are durable and do not crumble with use. They made my life easier.

Fits well. Better than the black rubber ones.

These are, after all, "only O-Rings" but try working without them when you need them! We are boutique manufacturers of wine service systems providing support for older, out-of-production product models to a global client base with only occasional needs. We no longer need to inventory the high minimum, 1-2,000+ piece orders once required when in full production of these models. Sterling makes reasonable, smaller quantities available at proportionately reasonable prices. I don't know how, but commingled with a few other commercial-use tidbits in a normal Amazon Prime order, these O-Rings arrived overnight - within 24 hours of placing the order. Can't ask for better!

Used to replace OEM o rings

Quick service great quality

Correct size, works fine for the end of our propane nozzle to refill tanks

they fit ,100 for 10 bucks,instead of one for couple bucks at the local RIP-OFF propane dealer and theses are silicon better than buna rubber... @ 10 cents ea you can give them to others in need .

Thicker than what is advertised. Compared them to standard rubber O rings and they are not the same.

Finally I’m not changing the o ring 3-5 times a day due to the heated water pressure washer destroying them. I’ve had to change it once since my purchase. Highly recommend for pressure washer’s with heated water👍.
