Avery ★★★★★

I needed a bulk pack of these for a hydraulic repair job, and the 70 durometer feels just right for making consistent seals without being too stiff. The 0.859" ID lined up perfectly with the groove measurements I checked against the standard AS568 chart.

Leo S. ★★★★★

The 70-durometer seals fit perfectly into the grooves on my pump rebuild, and the FDA-compliant material gives me peace of mind for food-contact lines. Four hundred o-rings for this price is a solid deal, and they held up fine through a hot wash cycle without any swelling.

Joseph ★★★★☆

These o-rings fit perfectly in my food-grade pump rebuild, and the 70 durometer feels exactly right for the sealing surfaces. The only thing I noticed is that a few of them arrived with slight surface marks, but nothing that affected the seal once installed.
