Customer Reviews (4.6 / 5 · 5 reviews)

Christopher G. ★★★★★

The 50 durometer is noticeably more pliable than the standard 70 I usually buy, which made seating them in a large pneumatic cylinder much easier. The 2.734" ID was spot on, and they sealed perfectly on the first try.

Violet ★★★★★

Used these o-rings to rebuild an old hydraulic valve, and the 50 durometer rubber sealed perfectly without being too stiff. The -40°F to +250°F rating gives me confidence for outdoor equipment that sees all seasons.

Andrew ★★★★★

The 2.734" inner diameter fit my cylinder perfectly, and the 50 durometer is pliable enough that seating them was a breeze. I've got them handling 200°F water without any softening, so the nitrile range checks out.
