Question by: Freddie A on Mar 29, 2025, 11:29 AM

does this tubing hold up in real cold weather? asking cause we run brake lines on trailers that sit outside all winter and cant have anything cracking on us

Answer by: Customer Support on Mar 31, 2025, 6:31 AM

Rated down to negative 40 degrees, so genuine cold snaps are not going to be a problem. The polyamide alloy tube material holds its shape and flexibility even when temperatures drop hard overnight. Trailers sitting outside through a rough winter should be fine running this tubing.
