Frequently Asked Questions

This part is confirmed for the Hydra-Clean spray gun. For other sprayers or guns, check the official parts manual for your specific model to confirm compatibility.

No. It is the needle valve component used inside the spray gun valve system, not a complete valve assembly.

Inspect the valve seat, packings, and gland components in the gun. Replacing worn seals or seats helps ensure optimal performance and prevents future leaks.
