Description

Brass Bulkhead Coupling with a straight body for routing air brake and pneumatic lines through a chassis panel, frame or bulkhead on commercial vehicles. The brass body clamps through the panel from both sides and the tube passes straight through, so the line crosses the bulkhead without an extra union, bracket or clamp, while the straight shape keeps the run in line and free of side load. It is intended for air brake, ABS and EBS circuits on bus, truck and trailer air systems.

Supplied as part number 931 50 022 in the 931 series, the coupling is machined from H59 / H62 brass in natural brass finish, which resists condensation, road salt and oil mist and keeps its strength and thread accuracy from cold start to hot engine bay conditions. It is produced under ISO9001 and IATF16949 quality control, with dimension, thread and sealing face inspection before packing, so each batch assembles the same way on the line and in the workshop.

Push-in ends seat PA11, PA12 and PU air brake tube by hand and the fitting can be released and refitted during maintenance, so line repairs and panel rework do not need new hardware. Engineered for high frequency fleet maintenance and OEM replacement, the coupling suits bus, truck, trailer and semi-trailer air brake lines, including air suspension, and is packed neutral or with custom marking for distributor and OEM programs.

Notices

Open the packaging carefully, inspect the coupling body, sealing ring and tube ends for scratches or damage, and handle gently to avoid surface scratch or seal damage. Do not pull forcibly or bend sharply during installation to avoid safety risks of connection loosening and seal cracking. Installation should be performed by qualified personnel to ensure correct assembly, stable sealing performance, and service safety.
