Customer Reviews (4.6 / 5 · 5 reviews)

Robert ★★★★★

Replaced a cracked seal on my hot water setup and these held up through a 400°F cycle without any softening. The red color makes them easy to spot if one ever rolls off the bench.

Ella J. ★★★★★

These fit perfectly on my pump housing, and the 70 durometer feels sturdy without being hard to seat. The red color makes them easy to spot during disassembly, and the -80°F rating gives me peace of mind for my cold-line applications.

Violet ★★★★★

The temperature range on these is what sold me—my last batch of rubber rings cracked in the cold, but these handle -80°F without turning brittle. The red color also makes them easy to spot when I'm swapping them out on the line.
