Applications
Universal-fit emergency-line gladhand for Class 6–8 tractors and trailers with SAE J318-compliant air brake couplings, including Freightliner, Kenworth, Peterbilt, Mack, Volvo, Western Star, and International heavy-duty trucks and any matching trailer.
For the matching service-line (blue) gladhand, see Phillips 12-136.
Red gladhand is for the emergency (supply) line only. Color polarity is critical for safe air brake operation — never substitute a service-line (blue) gladhand on the emergency circuit.
