Customer Reviews (4.6 / 5 · 5 reviews)

Mia ★★★★★

These are perfect for a quick seal replacement I did on a hydraulic line. The 70 durometer feels firm enough to hold pressure but still easy to seat in the groove.

Zoe B. ★★★★★

The temperature range on these is exactly what I needed for a hydraulic repair in an unconditioned shed. They slipped on easily and sealed tight the first try without any leaks.

Sofia ★★★★★

Finally found a pack that actually has the correct AS568-447 size, and the 70 durometer feels just right for my pneumatic fittings. These sealed up the leaky air line on my compressor first try.
