Frequently Asked Questions
A compression spring applies a constant preload or return force — ensuring that valves or pistons return to their default position and that seals are properly pressed together, which helps maintain fluid or air pressure control and prevents leaks or improper valve behavior.
Yes — 116411 is listed in authorized Graco spare‑parts catalogs as “SPRING, COMPRESSION.” :contentReference[oaicite:7]{index=7}
Replace the spring if the original becomes weak, deformed, corroded, or if the machine shows symptoms like poor valve return, leaking, inconsistent pressure or malfunctioning internal components. Always confirm part number and fit before installation.
