Compression Spring, Leybold, Trivac, D2.5E, D5E, Part# 490022 – vacstellar

It is the exact, Leybold part engineered for your specific pump model. It replaces part number 490022 (also known as cross-reference L0237).

Use it for your Trivac D2.5E or D5E pump. Replacing an old spring with this one restores the original, reliable action your pump was built for. It’s a simple fix that protects your pump’s health. 

This compression spring does a similar job inside your Leybold Trivac pump, but for a much more important task.

It’s a coil that gets shorter when squeezed. Inside the pump, it applies a steady, pushing force to another part. This could be to keep a valve closed, help control oil flow, or ensure a part returns to its correct position after moving.
