Joseph ★★★★★

I needed a batch of o-rings that could handle occasional hot water exposure, and these Buna-N ones with the square profile fit the bill perfectly. The 70 durometer feels sturdy without being too stiff, and the price for 400 pieces is hard to beat.

John ★★★★★

The square profile made a much better seal in my grooved fittings than standard round o-rings, and the 70 durometer feel is just right for a firm yet forgiving squeeze. I’ve already gone through half the box on various hydraulic repairs and haven't had a single leak yet.

Samuel ★★★★★

I've used these square-profile o-rings on several hydraulic fittings and the 70 durometer feels just right for a tight seal without being impossible to install. The pack of 400 is more than enough for my shop's needs.
