The -45°F lower limit is what sold me, since my garage setup sees some brutally cold mornings. They’re a bit stiff right out of the bag, but once seated they’ve held pressure without a single leak.

Installed these on a few pneumatic fittings and the 70 durometer gave just the right amount of squeeze without being too hard to seat. The -45°F to +250°F range covers everything I need in the shop. A solid batch for the price per pack.

These o-rings fit perfectly on my hydraulic fittings, and the neoprene material feels way more durable than the rubber ones I used before. The temperature range down to -45°F gives me confidence for outdoor winter use.
