Copper Sealing Washer for the oil drain plug of the LT77 and R380 manual gearboxes.

The washer forms a leak-free seal between the drain plug and the gearbox casing when torqued to specification. It should be replaced each time the gearbox oil is drained to ensure a reliable seal and prevent weeping from the drain plug.

Frequently asked questions

What is the FTC4112 copper washer used for on a Land Rover gearbox?

The FTC4112 is a copper sealing washer that sits under the drain plug on LT77 and R380 manual gearboxes. It compresses when the plug is tightened to prevent gear oil from leaking past the drain plug threads.

Should the FTC4112 copper washer be replaced at every gearbox oil change?

Yes, the FTC4112 is a single-use seal. Copper washers work by deforming slightly under torque to create a seal — reusing a previously compressed washer risks a slow gear oil leak. Replace it each time you remove the gearbox drain plug.

Does the FTC4112 fit both the LT77 and R380 gearbox?

Yes. The FTC4112 fits both the LT77 (used in Defender, Discovery 1, and Range Rover Classic) and the R380 (used in Defender Td5, Discovery 2, and Range Rover P38). Both gearboxes use the same drain plug washer specification.
