Compression Spring – Leybold, Trivac, Part# 490021 – vacstellar

Description

This is the replacement Leybold part made for this purpose. It replaces part number 490021 (also known as cross-reference L0238). It’s engineered to provide the exact strength needed for your pump’s design.

Use this compression spring for your Trivac D8B, D16B, D25B, D40B, D65B pumps and their S-Series equivalents (S8B, S16B, S25B, S40B, S65B). Replacing a worn-out or broken spring during maintenance restores the proper mechanical action your pump needs for reliable performance.
