Product Questions & Answers (2)

Question by: Brent G on May 30, 2025, 9:54 PM

What's the temperature range on this hose assembly? Got rigs running in some pretty brutal winters and hot summers both, need to know it'll hold up.

Answer by: Customer Support on Jun 1, 2025, 6:06 AM

Rated from -40°F up to +200°F, so it handles both hard freezes and high-heat summer conditions without issue. For air brake chamber lines running through seasonal extremes, that range covers just about anything you'd throw at it in regular over-the-road or fleet use.

Question by: Jimmy E on Mar 5, 2026, 1:01 PM

trying to replace an air brake chamber line i’ve got, what are the ends on this hose assembly?

Answer by: Customer Support on Mar 6, 2026, 3:01 PM

Both ends are 1/4 inch male pipe threads, but one side is a rigid male pipe and the other side is a 1/4 inch male pipe swivel adapter. The hose itself is 3/8 inch I.D. and the overall assembly length is 36.125 inches.
