Busch Filter Cover Gasket, Lower Part# 482500089 – vacstellar

This part, Busch #482500089, is specifically the Lower Filter Cover Gasket. It creates the seal at the base of the filter housing. It works together with an upper gasket to make sure the entire assembly is airtight.

Air leaks are the enemy of a strong vacuum. Even a tiny leak can make your pump work harder. It can reduce its power and efficiency.

This lower gasket ensures the bottom connection of the filter housing is sealed tight. It stops unfiltered air from sneaking in. It also keeps the vacuum pressure locked inside the system where it belongs.

Using the correct lower gasket means the entire filter cover sits perfectly. This protects the sensitive filter element inside from damage. It keeps your pump’s intake air clean
