does this tubing hold up in cold weather or does it get stiff and crack on ya?

Answer by: Customer Support on Apr 4, 2025, 10:51 AM

Rated down to negative 40 degrees, so cold snaps that would make lesser tubing brittle won't phase this one. The polyamide construction handles low temps without losing flexibility, which matters a lot when you're dealing with air brake systems that need to stay responsive no matter what the thermometer says.
