Customer Reviews (4.2 / 5 · 5 reviews)

Emily R. ★★★★★

The 70 durometer feels just right for the fuel line connections I needed, and the -40°F rating gives me confidence for winter use. No issues with fitment at all.

Matthew ★★★★★

The temperature range was exactly what I needed for my hydraulic lines that see some cold winters. All 20 rings were consistent and the 70 durometer feel is solid without being too stiff to seat properly.

Samuel V. ★★★★☆

These fit well on my hydraulic cylinder, and the -40°F temperature rating gives me peace of mind for winter use. They arrived in a sealed bag, though I wish the package included a few extras just in case.
