Question by: Jerry J on Jun 30, 2025, 2:02 PM
running this on a tractor-trailer setup, will it hold up to the -40 cold we get in the winters out here? need something that aint gonna stiffen up and crack on me
Answer by: Customer Support on Jul 2, 2025, 6:53 AM
Cold weather performance is built into this hose from the ground up. The minimum working temperature is rated at -40F, so it is engineered to stay flexible and functional in the kind of deep cold that causes cheaper hoses to get brittle. The EPDM tube and cover materials hold up well in those conditions, and the lightweight nylon construction helps it flex without fighting you during installation or when lines shift under load.

got a tractor to trailer setup, is this H338 hose meant for the service air brake line or is it for something else
Answer by: Customer Support on Jun 10, 2025, 6:37 AM
For tractor to trailer service air brake lines, tractor service air brake lines, and axle chamber lines, the H338 is a match for those common air brake runs. It is built as an air brake hose with DOT FMVSS 106 and DOT AII compliance, and it also meets SAE J1402A and SAE J1402.
