Question by: Rhonda R on Oct 7, 2025, 11:25 AM

does this tubing hold up alright in real cold weather, like well below freezing?

Answer by: Customer Support on Oct 9, 2025, 6:08 AM

Rated down to -40 degrees, so genuine cold snaps are not a problem for it. The polyamide construction keeps it from getting stiff and brittle in low temperatures, which matters a lot when you're dealing with air brake systems sitting outside overnight in hard winters.
