Description
This is the official Busch part (number 488000160). It is designed to fit perfectly in Busch Seco dry vacuum pumps from the SV series.
Over time, the original felt washer can get clogged with dust or break down. When that happens, it can’t hold oil properly. You might notice more noise or increased wear.
Replacing it with this part restores the proper lubrication flow. It’s a small, inexpensive part that plays a big role in protecting your pump’s lifespan and performance.
