220pc Assorted Sump Plug Washers Box - 16 Sizes, 12mm to 22mm

220pc Assorted Box of Sump Plug Washers - 220 oil drain plug sealing washers in sixteen sizes from 12mm to 22mm bore, covering copper, aluminium, fibre, nylon, rubber, bonded seal and compression types.

A sump washer has one job and it only does it once: it crushes or deforms into the face of the sump as the plug is pulled up, and that is what stops a slow weep down the back of the pan. Different manufacturers specify different types, so a box carrying seven of them across sixteen sizes covers most of what comes through a workshop rather than only the cars that happen to use one kind.
