Description
Midland Industries 38318 is a DOT-compliant air brake reusable union fitting in brass, sized for 3/8″ inside-diameter SAE J1402 / FMVSS 106 air brake hose with a 31/32-20 thread. Reusable construction means the fitting can be disassembled and re-installed onto a freshly cut hose end without crimping equipment, joining two lengths of 3/8″ ID brake hose into a single straight run.
