WASHER - COPPER SEALING (Clark CL3726791)

A damaged copper sealing washer can allow fluid to escape past a threaded fastener or drain plug. During routine disassembly, a technician may find the old washer crushed or deformed beyond reuse. The washer's soft copper material compresses under torque to create a leak-resistant seal between mating surfaces. Keeping a copper sealing washer in sound condition helps prevent gradual fluid loss that could lead to component damage. This aftermarket replacement part references Clark catalog number CL3726791.
