Henry B. ★★★★★

Had to swap out a few Buna-N seals in a hot oil line that kept failing, and these Viton rings handled the 300°F service without any softening. The 0.921" inner diameter seated perfectly in the groove, no fighting or stretching. Wish I’d bought these from the start instead of wasting time on cheaper

Matthew ★★★★★

The 75 durometer on these Viton rings feels just right for a snug seal without being too stiff. Installed a few on a high-temp fuel line and they’ve held up perfectly in the 400°F range so far.

Aurora ★★★★★

I needed o-rings that could handle the heat near my engine, and these Viton FKM ones with the -15°F to +400°F range have held up perfectly through several cycles. The 75 durometer feels durable, and the 0.921" inner diameter fit snugly on my compressor valve.
