Matthew ★★★★★

Needed a high-temp seal for a 400°F application, and these Viton rings handled it perfectly. The 75 durometer rubber feels tough but not brittle. Good price for a 65-pack.

Madison ★★★★★

Used one of these on a hydraulic fitting that’s seen some heat, and it sealed up perfectly without any distortion—the -15°F to +400°F range gives me confidence it’ll hold in extreme conditions. Even after a couple of thermal cycles, it hasn’t cracked or hardened. Solid buy for the price per pack.

Sofia ★★★★★

The 75 durometer hardness feels just right for my air line fittings—firm enough to seat properly without fighting you during install. I’ve got a set in a valve cover that sees 300°F regularly and they’ve been leak-free for two months straight.
