Customer Reviews (4.4 / 5 · 5 reviews)

Sebastian Q. ★★★★★

Fits perfectly in my hydraulic cylinder rebuild and held up great under constant 300°F heat. The brown color makes them easy to spot during inspection, and having 100 in the bag means I’ve got spares for the next few jobs.

Amelia ★★★★★

The 0.103" cross-section fit perfectly into my autoclave door groove, and the -15°F to +400°F rating gives me confidence for steam sterilization cycles. These brown o-rings feel dense and well-made right out of the package.

Penelope P. ★★★★★

I needed a high-temp seal for a hydraulic fitting that sees 350°F, and these Viton o-rings handled the heat without any swelling. The 75 durometer feels firm enough for a solid seal but still compresses easily with a wrench.
