Customer Reviews (4.4 / 5 · 5 reviews)

Natalie J. ★★★★★

These seal perfectly on my filter housing and the 70 durometer feels substantial without being hard to work with. The -65°F to +300°F range gives me peace of mind for outdoor winter use.

Thomas ★★★★★

Ordered these for a hot-water setup on a boat and the -65°F to +300°F range gives me total peace of mind, they've held up perfectly so far. The 70 durometer feels just right—firm enough to seat properly but not brittle when installing. Pack of 125 means I've got plenty of spares for the next few sea

Jason ★★★★★

The 0.21" cross-section on these #329 o-rings is perfect for the flange groove on my pump rebuild, and the 70 durometer feels solid without being too stiff. For this price per pack, I'm stocked up for years.
