Customer Reviews (4.4 / 5 · 5 reviews)

Mia X. ★★★★★

Took a chance on these o-rings for a small pneumatic project and the 70 durometer hardness is just right for a snug seal without being too stiff. They fit my AS568-157 groove perfectly and the black finish looks clean against the metal.

Carter ★★★★★

Replaced the old cracked seals on my hydraulic pump—these AS568-157s seated snugly into the groove without any wrestling. The -40°F rating gives me peace of mind for the cold months ahead, and a hundred fifty pieces means I’ve got spares for years.

Victoria V. ★★★★★

These 70 durometer o-rings fit perfectly in my compressor rebuild kit. The package of 150 should last me through plenty of projects.
