Case Seal Gasket, Leybold, Trivac, Part# 23811142 – vacstellar

Think of this gasket as the main seal for your pump’s body. It sits between the two halves of the pump casing.

Its job is simple but vital: to keep air out and the vacuum in. A tight seal here is what allows your Trivac pump to create and hold the powerful vacuum your process needs.

Over time, gaskets can wear out or get damaged. Replacing this case seal during maintenance restores your pump’s original performance. It prevents leaks that can reduce pumping power and efficiency.

This is the official Leybold replacement part (23811142). It is engineered to fit perfectly on a wide range of Trivac S-Series and D-Series pump models. Using the correct gasket ensures a reliable seal and a long service life for your equipment.
