Customer Reviews (4.8 / 5 · 5 reviews)

Scarlett Z. ★★★★★

Installed these on a high-temp pump application and the EPDM material has held up perfectly at 250°F for three weeks now. The 550-count box gives me plenty of spares for future maintenance, which is a nice bonus.

Nicholas ★★★★★

I was worried about sealing a hot water tank fitting at 180°F, but these EPDM rings held up perfectly with no swelling or leaks. The 70 durometer feels just right for this application, not too hard or soft.

Victoria ★★★★★

I needed EPDM o-rings for a high-temp outdoor application, and the 70 durometer feels firm enough to hold seal without being brittle. The -65°F to +300°F range gives me confidence they'll last through both winter and summer.
