Michael ★★★★★

The temperature range on these is the big win for me—they've handled hot water lines all week without any softening. The 70 durometer feels just right for a snug seal, and getting 550 in a pack means I've got spares for years.

Natalie ★★★★★

Finally found a source for these that actually seals properly on my hydraulic fittings. The 70 durometer feels exactly right for the moderate pressure I'm running, and the temperature range was the clincher since my setup sees over 250°F occasionally.

Victoria ★★★★★

I’ve been using these for sealing outdoor irrigation connections, and the EPDM holds up perfectly even under direct sunlight. The 70 durometer gives just enough flexibility without feeling flimsy during installation.
