Customer Reviews (5.0 / 5 · 5 reviews)

Grace C. ★★★★★

These X-rings seated perfectly in the hydraulic fitting on my press, and the 70-durometer Viton feels substantially tougher than the Buna-N I was using. The 0.139" cross-section provides a noticeably snugger seal.

Harper ★★★★★

I was worried about high-temp sealing on a compressor port, but these Viton o-rings held up perfectly at 350°F. The 0.139" cross-section gripped the groove tight without deforming, and they came neatly packaged. Exactly what I needed for a solid seal.

Aurora ★★★★★

I needed a sealed fit for a chemical sprayer that hits 300°F, and these Viton rings handled it without any swelling or cracking. The 0.139" cross-section felt nice and sturdy during installation.
