Edward D. ★★★★★

Used a couple of these today to replace worn seals on a pneumatic valve, and the 70 durometer gave a nice snug fit without being too stiff. The batch was consistent in size and had no flash or imperfections.

William ★★★★★

Just finished rebuilding a hydraulic cylinder on my tractor and these dash 156 rings sealed it perfectly the first time. The 70 durometer feels like the right balance of flexibility and toughness for the pressure I'm running.

Richard ★★★★★

The temperature range on these o-rings is exactly what I needed for a hot water valve rebuild. They seated easily and feel dense, much better than the old hardened ones I pulled out.
