Harper ★★★★★

The 0.21" cross-section on these #342 o-rings gives a nice snug fit in my pump housing without needing to force them. I've used them up to about 200°F so far with no leaks or hardening.

Eli Y. ★★★★★

These seals are holding up perfectly in my hot water recirculation line that sees constant thermal cycling. The 70 durometer hardness gives them just enough give to seat properly without squishing out of the groove. For the price per pack, they're a solid deal if you need a variety of spares around

Abigail Q. ★★★★★

Ordered these for a hot-water heating setup and the EPDM compound handles the temperature range without any issue so far. The 0.21" cross-section seats nicely in the groove, and the bag of 26 gave me plenty of spares for the price.
