Customer Reviews (4.6 / 5 · 5 reviews)

Scarlett S. ★★★★★

I was pleasantly surprised by how well these o-rings seal on my hydraulic fittings—the 0.139" cross-section really grips tight. The package of 500 is more than I’ll use this year, but the price is right to have extras on hand.

Harper ★★★★★

The 90 durometer hardness is exactly what I needed for a high-pressure application—these don't squish out like the softer ones I've tried. The -40°F rating gives me peace of mind for outdoor equipment in winter, and a box of 500 means I won't be reordering anytime soon.

Eli E. ★★★★★

Had to replace some worn-out seals in a hydraulic assembly and these AS568-213 o-rings were a perfect fit. The 90 durometer feels nice and firm, and the 500-count pack means I have spares for the next job. Exactly what I needed.
