Truck air-brake air assembly

The Velvac 22639 is a 15 ft coiled air assembly set designed for truck air-brake and auxiliary air systems. It includes brass fittings on both ends for direct connection to existing brake lines. The tubing handles a maximum operating temperature of 200 Degrees F and offers a bend radius of 5 1/2 in for routing in tight chassis spaces. The red and blue colour coding identifies emergency and service circuits at a glance.

Brass NPTF fittings included

Each end of the assembly arrives with a straight female brass fitting sized 1/2 in with a thread size of 14 and NPTF connection type. These factory-fitted ends eliminate the need to source or crimp separate couplings during installation. The brass construction resists corrosion from road salt and moisture over long service intervals. Fittings are ready to thread into compatible ports without additional sealant in most standard configurations.

Verify port thread and hose routing

Before ordering, confirm that the vehicle brake ports accept 1/2 in NPTF female threads with a thread size of 14. Measure the routing path to ensure the 15 ft coiled length and 5 1/2 in bend radius suit the chassis layout without stretching or kinking. Check that the maximum operating temperature of 200 Degrees F matches the system requirements for the intended application. Ensure local regulations permit this assembly for the specific vehicle class.

Questions about this item

How often should the brass NPTF fittings on this 15 ft coiled air assembly be inspected or replaced?

Inspect the brass fittings at every scheduled brake-system service; replace them if threads show deformation, corrosion or if leaks appear at the 1/2 in NPTF connections.

What is the first limit reached when this air assembly runs continuously in a truck brake system?

The 200 °F maximum operating temperature is the primary limit; sustained heat above that point degrades the tubing material and fitting seals.

How much heat does the tubing generate during all-day operation and does it need extra cooling?

The assembly itself adds no heat; it simply carries compressed air up to its 200 °F rating, so no active cooling is required beyond normal airflow around the lines.
