Sump Plug Washer - copper sealing washer for the sump drain plug and thermostat housing on petrol and early diesel engines.

The copper washer seats between the plug or bolt head and the mating aluminium or cast-iron surface. Under torque, the soft copper deforms to fill surface imperfections and create an oil-tight seal. Replacing the washer at each oil drain prevents seepage from a work-hardened washer that can no longer conform to the mating surface.

Frequently asked questions

What is the 243959 sump plug washer used for?

The 243959 is a copper crush washer that seals the engine sump drain plug and thermostat housing on early Land Rover petrol and diesel engines. The soft copper deforms under the plug's clamping load to fill surface imperfections and create an oil-tight seal. Fits Series II/III, Defender (1983-2006), Discovery 1 (200TDi, to VIN LA081991), and Range Rover Classic.

Should the 243959 sump plug washer be replaced at every oil change?

Yes, replace the sump plug washer every time the plug is removed. Copper work-hardens after its first seating and can no longer deform reliably to seal the mating surface. Reusing the old washer risks a weeping seal around the sump plug after reassembly.

What is the difference between the 243959 sump washer and the 515599 drain plug washer?

The 243959 is for the engine sump plug and thermostat housing on petrol and diesel engines. The 515599 is for axle differential drain plugs on Series 1/2/3 and Range Rover Classic axles. Both are copper crush washers but serve different locations: engine block versus axle casing.
