Replace the filter when damaged, deformed, or after persistent clogging.
Match mesh to material: 50-mesh for latex/primers; use finer mesh for thinner coatings.

Frequently Asked Questions

No. It specifically fits guns designed for this assembly: SG2, SG3, and the Original Contractor Gun. For other guns (Contractor PC, FTx, etc.), verify the correct filter part number in the gun’s parts list.

50-mesh is well-suited to most latex paints and primers. For thinner materials (stains, lacquers), a finer mesh may improve finish and reduce nibs.

Replace if the filter is torn, crushed, permanently discolored, or if you experience frequent tip clogs and flow restriction even after thorough cleaning.

It’s not recommended. The gun filter protects the tip and improves finish quality. Running without it increases the risk of debris causing tip plugging and poor patterns.

Always relieve pressure, remove the handle cap, swap the filter, and reinstall firmly. Prime/flush after replacement to purge trapped debris.
