Customer Reviews (4.6 / 5 · 5 reviews)

Hazel M. ★★★★★

These sealed perfectly on the first try, which is a relief since I hate redoing plumbing jobs. The 70 durometer hardness feels just right for the pressure I'm running, and the -40°F to +250°F range covers everything I need in my shop.

Zoe ★★★★★

Finally got around to swapping out the old rubber seals on my hydraulic filter housing, and these 70 durometer Buna-N rings seated perfectly without any binding. The -40°F temperature rating gives me peace of mind for winter use, and the pack of 14 should last me a while.

Jacob ★★★★★

I needed these for a hydraulic repair and the 70 durometer feels just right—not too stiff, not too soft. The package of 14 is perfect for a job like mine without leaving a ton of extras. They slipped into place easily and held pressure with no leaks.
