Customer Reviews (4.8 / 5 · 5 reviews)

Richard ★★★★★

The cross-section is exactly 0.21" as specified, and I've already used half a pack on a hydraulic pump rebuild. These o-rings fit perfectly into the grooves without any distortion.

Ruby ★★★★★

The 70 durometer feels just right for my air compressor rebuild—tight seal without being too hard to install. These 327s fit the groove perfectly, and the 200-count bag should last me years of projects.

Avery ★★★★★

I needed a reliable seal for a hydraulic line on an older machine, and this 327 size hit the mark exactly. The 70 durometer feels firm yet flexible, and the nitrile material handles the occasional high heat without any issues.
