008 Silicone O-Ring, 70A Durometer, Red, 3/16" ID, 5/16" OD, 1/16" Width (Pack of 100)

Since the O-Ring of the steam wand on my Breville Barista Express split and steam was coming out where it wasn't supposed to, I've been trying to find a replacement. Unfortunately the replacement from Breville doesn't list the size and is between $3 and $7 for one replacement. Since that seems very overpriced I looked elsewhere. I can't speak to the longevity of these since I just got them, but it was easy to install, fits well, and appears to work as well as the OEM one before it broke. I do wish these came in smaller packs (3 or 10) because I'm not sure what to do with the other 99. Definitely a good value for the money considering that if I have to replace it one more time it will have paid for itself compared to Breville.

A GREAT PRODUCED O RING WITH EXTREME ACCURACY AND SPECIFICATIONS. BETTER THAN THE O RINGS THESE REPLACED AND WELL PACKAGED.

I've been knitting a VERY long time and found the best markers were little red rubber/ silicone rings that, in a variety of sizes, slid easily on and off knitting needles without sliding off at unwanted times( which not only loses your place, but also allows open stitches to slide off into the unknown). I can no longer find those great little rubber rings, so I turned to these silicon o rings. They are a GREAT substitute. Product came promptly and was a reasonable price. Would definitely recommend Sterling Seal

These can prevent bottoming out of the keycaps on a Cherry (or equivalent) mechanical switch keyboard. Really quiets the keys down, and especially good with the otherwise-silent red switches.Ensure that the switch top looks like a + (plus) sign, and the keycap bottom is cylindrical and about 3/16" in diameter. Most keycaps need one of these. Sometimes the upper row keycaps can take two each.

Nice quality O-rings at a good price. Fast shipping.

Sized correctly. No issues.

Excellent quality

The price is reasonable. However, the size 008 O-rings don't meet the AS568 standard as stated in the description. I took 3 random o-rings from the bag and checked the thickness with dial caliper and micrometer. Just to make sure measurements are correct, I measured 4 difference cross section spots on each sample o-ring. Results are usually outside of the standard 0.07 plus or minus .003 inches. So I sent them back. The search continues.

Good
