Penelope T. ★★★★★

The 50 durometer on these o-rings makes them nice and pliable for a tight seal. A full 110-piece package is way more convenient than running to the hardware store for singles. They fit perfectly in my hydraulic valve rebuild kit.

Violet ★★★★★

Replaced some old seals in my air compressor and these 50 durometer 223s fit perfectly—much softer than the originals, which made seating them way easier. The -40°F range gives me peace of mind for winter shop use, and the hundred pack means I'm set for a while.

Joshua ★★★★★

Needed some 223 o-rings for a hydraulic repair job where the old ones were too stiff; these 50 durometer rings seated perfectly in the groove and sealed right up. The kit came packed securely with all 110 pieces separated by size, which saved me a trip to the supply house.
