Customer Reviews (4.2 / 5 · 5 reviews)

Ryan W. ★★★★★

The cross-section thickness on these is exactly what I needed for a tight hydraulic seal. They slid into place without any tweaking and have held up well under high heat so far.

Carter ★★★★★

The heat resistance rating is what sold me, since my engine bay easily tops 300°F, and these Viton seals haven't softened or cracked after a month of daily driving. The 75 durometer stiffness feels right for the grooves, and a full bag of 250 means I won't be scrambling for spares anytime soon.

Nicholas ★★★★★

I was skeptical about whether these would seal my hydraulic fitting at 350°F, but the Viton compound held up perfectly with no leaks. The 75 durometer feels just right for a snug fit without being impossible to install. Exactly what I needed for a high-heat application.
