Our Tectran and Phillips, Haldex and TruckLite trailer connectors are J2222 compliant. The new SAE J2222 contains numerous improvements for Trailer connectors, and butt connectors. The most notable of which is a tightening in the requirement for sag resistance of Trailer connectors. The previous document allowed sag of as much as 54¿ on a 15 ft coiled cable! Sag-and-drag is a common cause of coiled cable Trailer connector failure. The new Trailer connector Standard dramatically improves the performance criteria, more clearly defines working length and works in conjunction with the TMC Recommended Practices relating to the selection, installation and maintenance of Trailer connectors.
