Brian N. ★★★★★

These fit my compressor rebuild perfectly—the 1.986" ID is exactly to spec and the 70 durometer stiffness feels right for the sealing surfaces. The -40°F to +250°F range gives me confidence for outdoor equipment.

Andrew U. ★★★★★

Used half a pack sealing a custom air manifold setup, and every ring seated perfectly without any trimming. The 70 durometer feels just right for a snug fit without being too hard to work into the groove.

Ella ★★★★★

Installed these on a hydraulic cylinder assembly and the 1.986" inner diameter fit perfectly over the piston. The 70 durometer material feels firm enough for the moderate pressure seal I needed.
