Customer Reviews (4.8 / 5 · 5 reviews)

Emma ★★★★★

The temperature range on these EPDM o-rings covers everything I need, from cold storage to hot water lines. They seated perfectly on my first try, and the 130-count bag will last me through several projects.

Sebastian ★★★★★

Needed these 313 o-rings for a hydraulic repair and the fit was perfect—no leaks after several cycles. The 70 durometer EPDM handles the heat well so far, working as expected.

Amelia ★★★★★

Cross-section is exactly 0.21" as listed, and they fit perfectly in the groove I machined for a -313 size. The rubber feels pliable but firm, and after a week submerged in hot coolant there’s no swelling or leaks.
