7 Pin Socket - Solid Pin Wire Insertion Zinc Die-Cast 2 Hole Mount - Phillips 15-721 Grote 82-1005 PHI15-721

Fix the intermittent trailer at the source with this 7 pin trailer socket from Phillips, distributed by FleetPro Parts & Tires. The receptacle on the back of the tractor is where every trailer circuit passes through, and it is the part that lives in salt spray with its lid flapping. When the pins corrode, the lid spring gives up or the housing cracks, the connection drops out over bumps and the driver chases ghosts through the trailer harness that was never at fault. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, trailer repair shops, and owner-operators nationwide.

Solid Pins, Sealed Lid: The Wire Insertion Socket Advantage

This socket uses solid pins with wire insertion terminals, so each conductor lands directly in a one-piece pin instead of relying on a crimped tail that works loose with vibration. The heavy-duty zinc die-cast housing takes the knocks and the weather that split lighter bodies, and the stainless steel hinge pin and spring keep the lid closing under its own force years after a plated spring would have rusted open.

It mounts with a 2 hole mount whose elongated holes give real mounting adaptability, so it lines up on an existing bracket instead of forcing new holes. For added protection at the cable entry, use the 179.67072B socket boot, sold separately. This socket is a direct replacement for highly searched industry numbers including Phillips 15-721, Grote 82-1005 and Tectran 670-72A, plus Tectran 38199, Tramec Sloan 421124 and Velvac 593083.
