Customer Reviews (4.6 / 5 · 5 reviews)

Violet ★★★★★

These are exactly the right size for the hydraulic cylinder rebuild I’ve been putting off, and the 70 durometer hardness feels like the proper firmness for a tight seal. The 267 dash number was easy to match to my old ones, and the 50-count bag means I have spares for the next job.

Ellie E. ★★★★★

I needed a set of larger o-rings for a hydraulic cylinder, and the 7.734-inch inner diameter on these was spot-on. The 70-durometer rubber feels sturdy enough to handle the pressure, and they seated perfectly in the groove.

Elizabeth B. ★★★★★

These are replacing old o-rings on a large pneumatic cylinder, and the 70 durometer feels just as firm as the originals. Installed easily and held a seal with no leaks during the first test run.
