George V. ★★★★★

Put these in my hydraulic press seal kit and the square profile made installation a breeze compared to round o-rings. The 70 durometer seal is firm enough to hold pressure but still easy to seat with a pick.

Henry ★★★★★

The 70 durometer feels just right for the air fittings I’m sealing—they compress without deforming. Having an 800-count pack means I won’t run out mid-project.

Mia X. ★★★★★

The square profile seats much better than standard round o-rings for my hydraulic fittings, and the 70 durometer feels just right for a tight seal without being too stiff. Ordered the 800 pack and every single one was clean and uniform, no flash or defects. Definitely my go-to for this size now.
