Customer Reviews (4.8 / 5 · 5 reviews)

Julian U. ★★★★★

Was surprised to get 1,200 rings for the price, and the -40°F to 250°F range covers my hydraulic repair work just fine. No leaks after a week of use.

Joseph E. ★★★★★

The 90 durometer makes these feel properly rigid—no squishy deformation when I torque fittings down. A full box of 1200 means I won't run out mid-project for a long time. The -40°F rating gives me confidence for outdoor gear.

Timothy ★★★★★

I needed a bulk pack of these for a pneumatic project, and the 90 durometer hardness gives them a nice, firm feel during installation. They fit the grooves perfectly and seem like they'll hold up well across the full temperature range.
