Part 4036ER4001F Outer Tub Gasket / Seal

Purpose

Seals outer tub to prevent leaks

Details

This is the OEM outer tub gasket (seal) used in many LG washing machines. It provides a watertight barrier between the outer casing and inner tub, preventing water from leaking out the back or bottom. Over time, gaskets may degrade, crack, or lose flexibility, leading to leaks, dripping, or moisture buildup in the base. Replacing the worn gasket restores a reliable seal and protects other internal components from water damage.

Included Items

One molded tub gasket / seal ring.
