Customer Reviews (4.8 / 5 · 5 reviews)

Ruby ★★★★★

I needed o-rings that could handle high heat near a turbocharger, and these Viton ones are holding up perfectly at 400°F after a month of use. The 90 durometer material feels firm and durable, sealing tight without any leaks.

Andrew ★★★★★

Installed one in a hydraulic fitting that sees 350°F steam cycles, and it's held its seal perfectly for over a week now. The 90 durometer feels noticeably firmer than standard Viton, which gives me confidence it'll last. At 250 per pack, this is a solid deal for high-temp applications.

David ★★★★★

These 250-count packs are exactly the right size for my 400°F application, and the Durometer 90 material holds up perfectly under pressure. The price for this quantity is hard to beat for what you get.
