2 x Magnetic Drain Plugs / Level Plugs.
Part Number :- GL1094, Pair Magnetic Drain / Filler Plugs
Weight :- 200g
Fits:- all Defenders / Discovery 1 / RRc / axles, will also fit the LT230 Transfer Box level plug.
These are the same thread as a standard level or drain plug (3/4 BSPT), they also have the 1/2″ square hole in them to undo or tighten them, the main benefit is they have a magnet fastened onto them that will catch any bits of metal floating around in the axle or diff, I always use 2 per axle, 1 as the drain plug and 1 as the level plug, it is a good thing on the level plug as when you check the oil if there is contamination on there you know something is going wrong before it is to late.
