Pollak 11-780 Neoprene Mounting Gasket for 3-Hole 7-Way Trailer Sockets

A Professional Seal for Maximum Weather Protection The Pollak 11-780 Neoprene Gasket is an essential preventative maintenance component for heavy-duty vehicle-side trailer connectors. Specifically engineered for 3-hole mount die-cast zinc sockets, this gasket creates a compressed, weather-tight seal between the socket flange and the vehicle’s mounting surface. By blocking out moisture, road salt, and dirt, the 11-780 prevents the corrosive "green rot" that typically destroys rear-terminal electrical connections.

Dual-Purpose Performance: Seal & Template Constructed from high-grade, durable neoprene rubber, this gasket remains flexible and crack-resistant even when exposed to extreme temperatures, UV rays, and road chemicals. A standout feature of the 11-780 is its precision-cut design, which allows it to double as a mounting template. This simplifies the installation of new sockets by providing an accurate guide for marking and drilling, ensuring a perfectly aligned and professional-grade fit every time.

Commercial-Grade Reliability Recommended for every new 3-hole socket installation, this gasket is a staple for commercial fleets, agricultural equipment, and heavy-duty industrial vehicles. It is a universal fit for Pollak’s industry-standard SAE J560 7-way round pin sockets, helping to maintain electrical integrity and reduce downtime caused by lighting or brake system failures.
