Customer Reviews (4.4 / 5 · 5 reviews)

Olivia ★★★★★

The 50 durometer is perfect for my application—soft enough to seat easily but still holds a tight seal. For the price of a 325-pack, these are a steal compared to buying individually at hardware stores.

Robert M. ★★★★★

For a batch of 325, the price is unbeatable for this size and durometer. Used them to rebuild a pneumatic cylinder and they seated perfectly without any leaks, even at 100 PSI.

Abigail ★★★★★

Got these for a quick rebuild on an old pneumatic actuator, and the 50 durometer hardness is a perfect match for the original seals. The temperature range down to -40 is reassuring since this equipment sits in an unheated workshop all winter. A full bag of 325 for that price is almost silly value.
