Customer Reviews (5.0 / 5 · 5 reviews)

Lucy ★★★★★

These replaced some worn-out seals on a heated manifold that sees 300°F daily, and the Viton hasn't softened or deformed at all after a month of cycling. The 0.21" cross-section seated perfectly in the groove, so no leaks on the first try.

Emily ★★★★★

Used these for a high-temp hydraulic seal that kept failing with standard Buna-N—hundreds of hours in now with zero issues. The 0.21" cross-section fits snug and the brown Viton feels noticeably stiffer than what I was used to.

Victoria ★★★★★

Was skeptical about the brown Viton material holding up in high heat, but after a week on a steam line these o-rings haven't hardened or cracked at all. The 75 durometer feels just right for the seal.
