Customer Reviews (3.8 / 5 · 5 reviews)

Lily ★★★★★

These rings measure exactly right with my calipers, and the soft 50 durometer makes them seat easily without any wrestling. I've got a full box of 300 for every plumbing fitting in the house, which should last me years of rebuilds.

Madison ★★★★★

These seals handled a stubborn coolant leak on a 118-size fitting without a single drip after a week of daily use. The 50 durometer is noticeably more forgiving than harder rubber, which made seating them in the groove a lot easier.

Sebastian U. ★★★☆☆

The box arrived well-packed, and the 50 durometer hardness makes these noticeably pliable when installing. They seat fine in a standard groove, though I can't say they feel any more durable than cheaper packs I've used. Decent for the price if you need the exact AS568-118 size.
