Busch Oil Fill Plug Gasket Part# 48202000 – vacstellar

Replacing it is an easy and low-cost maintenance task. This Busch gasket is made from the right material to handle pump oil and heat.

A new gasket ensures a tight seal. This prevents oil loss, keeps your pump housing clean, and protects your workspace from drips.

The Oil Fill Plug Gasket sits under the metal oil fill cap. Its job is simple but important. It seals the gap between the plug and the pump body.

Think of it like the washer on a faucet. It creates a tight, leak-proof connection.

When this gasket gets old, it can become hard, flat, or cracked. It loses its ability to seal. This allows oil to slowly seep out, especially when the pump is warm and running.
