Copper Sealing Washer used to seal a threaded or banjo joint in the fuel and lubrication circuits.

The soft copper deforms under tightening to conform to the mating faces, forming a gas- and fluid-tight seal at connections such as banjo bolts, injector unions and drain plugs. Used across the diesel engine applications.

A copper washer is single-use: it should be renewed each time the joint is disturbed to ensure a reliable seal.

Frequently asked questions

What is the ERR1304 copper sealing washer for?

The ERR1304 copper sealing washer seals a threaded or banjo joint in the fuel and lubrication circuits. The soft copper deforms under tightening to match the mating faces and form a gas and fluid tight seal at points such as banjo bolts, injector unions and drain plugs.

Can a copper sealing washer be reused?

No, treat the copper sealing washer as single-use and fit a new one every time the joint is disturbed. Once compressed the copper work-hardens and won't seal reliably again, which typically leads to weeping fuel or oil at the joint.

How many copper washers will I need?

The quantity depends on the joint. A banjo union typically needs two washers, one each side of the banjo eye, while a drain plug or injector union usually takes one. Order enough to renew every washer you disturb.

Which Land Rovers does the ERR1304 fit?

The ERR1304 suits diesel applications across the Defender, Discovery 1, Freelander 1, Freelander 2 and Range Rover Classic, covering 200Tdi, 300Tdi, VM and 2.0 TDCi engines. It's a common-fit sealing washer rather than a model-specific part.
