I got these to replace the crap that held the bulb in F450 mirrors. Works like a champ. A lot better than oem!

Good quality material but these are not very flexible and do not have much stretch.

Used for damping some amplifier valves. Ordered 18mm for 19mm tube-perfect fit.

No problems so far and the O-rings seem to last a reasonable length of time.

Product looks to be of a great quality , sad thing is that it was not as described to be 21 mm ID .ID was more like 22 mm and my shaft that I needed to seal was @ 21.91 mm so seals were kind of loose on the shaft .. The OD was perfect .It was exactly what I needed but a touch bigger ....Returned items ..

I bought this so that I could repair one of my car jacks because one of the o-rings it had broke and this specific o-ring was that not common. Therefore I have found this product which matched the size and then repaired it but after a few days of use, the o-ring snapped.

Got these to replace the cracked and worn bilge plug gasket for my boat. These fit perfectly and this little bag will probably be a lifetime supply.

What's more to say really other than they arrived exactly as described in the quantity I'd expected, and in a timely manner. One thing I'd say though is make sure when measuring what you need these for that you're measuring the right diameter (inner or outer) and what sort of fit/compression you need them to perform.

These have thus far lasted at least a year and a half. Happy with the purchase and the price. Would buy again.

Likes: I like that the size I ordered was the size that I received. These O-rings are durable, I'm using mine in a different capacity as they also work for protecting the center shaft and legs on my Manon Tripod. Are even are cost competitive with other available o-rings.Dislikes: None...Yes I'd buy these again. They came quickly and solved my problem.
