Elizabeth A. ★★★★★

I’ve been using these o-rings in a high-temp oil seal application, and they’ve held up perfectly at 350°F without any hardening or leakage. The 0.103" cross-section gives a snug fit in the groove, and the 70 durometer feels just right for our seal design.

Olivia ★★★★☆

For a coolant line rebuild on a hot runner mold, these Viton rings held up perfectly at 350°F. The 0.103" cross-section seals nicely, though I wish the package included a few extra spares for the price. Still, they're a good buy for the temperature range.

Samuel K. ★★★★☆

I needed a high-temp seal for a steam valve and these Viton rings fit perfectly—the 70 durometer feels sturdy but not too stiff. They were a little snug to install initially, but once seated they've held up great through several heat cycles.
