Customer Reviews (4.8 / 5 · 5 reviews)

Brian V. ★★★★★

The 70 durometer is spot on - these seals fit perfectly and took the wobble out of my hydraulic valve after years of use. The -40°F tolerance was also reassuring for my outdoor equipment.

Jason ★★★★★

Used these to rebuild a pneumatic cylinder at work and the 70 durometer hardness felt just right for the seal. The -40°F rating gives me confidence for our cold storage lines, and at 400 per pack I'll be set for years.

Joshua ★★★★★

The dash 118 sizing was spot-on for my rebuild, and the 70 durometer feels firm but not brittle when I stretch them over the fitting. At 400 in a bag, I've got spares for the next few jobs without reordering.
