Product Questions & Answers

Does the temperature range on this seal hold up when things get real cold, like below zero? Got equipment that sits outside through winter and I need something that ain't gonna crack or fail when it first starts up in the morning.
Question by: Todd H on Apr 17, 2025, 6:42 PM
Rated down to -65°F, this urethane seal handles deep cold without going brittle on startup. The urethane material holds its shape and sealing ability well below freezing, so equipment that sits overnight in harsh winter conditions should still get a solid seal when it fires up. On the high end it's good to 220°F, so you've got a wide working range to cover most outdoor hydraulic applications.
