Customer Reviews (4.8 / 5 · 5 reviews)

Samuel C. ★★★★★

Replaced the old cracked seals on my air compressor and these slid right in with no fuss. The 75 durometer feels sturdy, and knowing they handle up to 400°F gives me peace of mind for the hot side of the system.

Timothy ★★★★★

These fit perfectly on the hydraulic fitting I was rebuilding, and the 75 durometer feels noticeably more durable than the standard ones I've used. The 40-minute charge time was a pleasant surprise.

Aurora ★★★★★

After struggling with temperature-related failures on my hot oil line, these Viton o-rings handled the 350°F service without any issues. The 0.103" cross-section seated perfectly into the groove. I'm confident they'll last much longer than the Buna-N ones I was using before.
