Customer Reviews (4.8 / 5 · 5 reviews)

Richard ★★★★★

The 70 durometer feels just right for my air compressor fittings, and the temperature range covers everything I need.

Natalie G. ★★★★★

I needed a custom size for a hydraulic line repair, and the AS568-419 fit perfectly on the first try. The 70 durometer feels firm enough for high-pressure applications without being brittle.

Riley ★★★★★

The temperature range on these is what sold me—I needed something that could handle both a freezer line and a hot water setup, and -40°F to +250°F covers it. The 70 durometer feels firm but not brittle when I stretched one over the fitting, and all 50 arrived in perfect shape.
