Overview

Build the hose end you actually need. This reusable swivel air brake hose coupling distributed by FleetPro Parts & Tires is field-assembly hardware for 1/2 in ID DOT rubber air brake hose and finishes the line in a 1/2 in swivel pipe fitting. When a big 1/2 in line lets go, the truck does not creep home on it โ€” the system dumps, the low-air alarm sounds and the spring brakes take the decision away from you. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Route It, Then Tighten It: The 1/2 In Swivel Coupling Advantage

The difference between this coupling and a plain fixed end is that the 1/2 in NPT connection swivels. On a fixed fitting you turn the whole hose to torque the joint and every degree of that twist stays locked in the rubber, pulling the line off its intended path and loading the ends. With a swivel you clock the hose where it belongs, then tighten the nut against the port. Nothing winds up, nothing pulls back, and the assembly relaxes into its natural arc.

As reusable fitting hardware it also means a damaged 1/2 in line is a hose repair, not a parts order. Cut back past the damage, rebuild the end and put the truck back to work. At FleetPro Parts & Tires we stock the fittings that keep a spool of hose useful. This Automann swivel coupling is a direct replacement for highly searched industry numbers including 33808BY88, 66RBSV878, 11078 and S363RB8, and it replaces the earlier 177.7105.
