Truck Plugs


Liquip offers truck plugs with added ground assurance to suit 2 wire and 5 wire overfill systems with 3 or 4 pin bayonet fastening (J-slots).

The industry standard 10 pin overfill protection is interchangeable with others of the same type and incorporates no-cost wiring connectors which ensure the tanker is bonded to the gantry so long as the plug body is correctly mounted. This dissipates static electricity and prevents sparks due to differences in potential.

The design of Liquip's truck plugs is unique in that it ensures grounding of the tanker to the gantry by using the mounting bolts inside the truck plug.

The TP104 series of truck plugs features a hard-coated nose ring and J-slots for longer service life.
