Description
Rietschle VC500 and VC700 are big rotary vane pumps that pull heavy vacuum in factories and workshops. They have inlet and exhaust filters to catch dust and bits from the air. This rectangular filter gasket, part number 519671, sits right in the filter assembly – often at the base or cover – to make a tight seal.
It keeps oil from leaking around the filter and stops unfiltered air from sneaking in. Without a good gasket, you could lose vacuum power or get dirt inside the pump, which wears things out faster. This one is built from strong material (likely neoprene or similar rubber/fiber mix) that handles oil and heat well.
It fits these models:
- VC500
- VC700
You will find it in major rebuild kits, filter service kits, and exhaust/inlet maintenance kits for these pumps. Technicians swap it in during filter changes or full overhauls to keep everything sealed up.
