Penelope ★★★★★

The dash 149 size matched the groove on my equipment exactly, no slop or forcing needed. At 70 durometer they feel firm but compress nicely, and the 250 count means I won't be scrambling for spares anytime soon.

Riley A. ★★★★★

The 0.103" cross-section fit perfectly into the groove on my air compressor head, and the 70 durometer feels just right for this application. After a month of daily use, no leaks whatsoever.

Isabella ★★★★★

I've been replacing seals on my hydraulic cylinder, and the 2.799" inner diameter slid right into the groove without any struggle. The 70 durometer feels firm yet pliable enough to create a solid seal at higher pressures.
