Customer Reviews (4.6 / 5 · 5 reviews)

Charlotte ★★★★★

The temperature range on these is exactly what I needed for sealing a hot water manifold in my workshop. They fit perfectly into the grooves and the 70 durometer feels durable without being too stiff. Exactly what I expected from a standard EPDM O-ring.

Violet ★★★★★

Installed these on a fuel distributor manifold for outdoor equipment and the 70 durometer holds its shape well under the hose clamp pressure. Already have a second bag on order.

Olivia ★★★★★

These fit perfectly on the pump housing I was repairing, and the 70 durometer stiffness feels right for the job. The -65°F to +300°F range gives me confidence they'll hold up in both my cold garage and near the hot water line.
