Christopher ★★★★★

These o-rings are holding up great in a high-heat application near my furnace, and the -65°F to +300°F range gives me confidence. The 0.139" cross-section feels properly thick and durable for a reliable seal.

Kevin I. ★★★★★

The -65°F temperature rating is exactly what I needed for outdoor equipment that sits through winter. These 238-size rings fit perfectly on the flange and the EPDM material feels high quality.

Michael N. ★★★★★

Bought these for a hydraulic rebuild on an old press, and the 70 durometer feels just right—not too stiff, not too soft. The pack of 55 is generous, and they slid into the groove perfectly with no distortion.
