Description
Overview:
The Flexible Socket Seal for 12S supplementary towing electric sockets is a compact gasket designed to protect 7‐pin connections on towbars. Made from durable, flexible polyurethane (PU) in a low‐profile form factor, it sits between the socket body and the mounting surface to keep out moisture and debris. This helps prevent corrosion and intermittent faults in trailer or caravan lighting and accessories. Sized at 7.3 cm x 7.6 cm x 1.7 cm (2.87 in x 2.99 in x 0.67 in) - approximately 73 mm x 76 mm x 17 mm - it provides a snug, reliable seal for standard 7‐pin 12S setups on cars, vans, 4x4s, and light commercial vehicles. Manufacturer Part Number: 761 390.
