1 in NPT Inlet Strainer for Airless Sprayers

An inlet strainer sits at the intake of an airless sprayer and catches lumps, dirt and paint skins before they reach the pump. This one has a 1 inch NPT thread, the common inlet size on many electric airless sprayers, and it keeps the inlet valve clear so the pump does not have to work against a blocked line.

Key Features

• 1 inch NPT inlet thread
• Strains paint before it enters the pump

What You Need To Complete The Job

Fit the strainer to the pump inlet and pair it with a suction strainer for older machines, then keep a clean gun filter at the gun end. The rest of the paint machine kit is in the Paint Machine and Accessories range.

Frequently Asked Questions

What does the inlet strainer protect?

It protects the pump inlet valve and the packings from lumps and debris in the paint. A blocked or missing inlet strainer lets dirt into the pump, which is the fastest way to wear out a sprayer.

How do I know my pump takes a 1 inch NPT?

Check the thread at the pump inlet, usually with a thread gauge or by comparing the fitting. Many electric airless sprayers use a 1 inch NPT inlet, while some older models use a 3/4 inch UNF. Match the thread to your machine.

How often should I clean it?

Rinse the strainer whenever you flush the sprayer, and check it when you change paint colours or start a new job. A blocked strainer starves the pump, which shows up as a surging spray pattern.

How do I know if the strainer needs cleaning?

Check the mesh when you flush the sprayer or change paint. A blocked strainer shows up as a surging spray pattern or a pump that labours. Rinse the mesh with the correct solvent and it is ready to go back on.

What is the difference between an inlet strainer and a gun filter?

The inlet strainer sits at the pump intake and catches large debris before it reaches the pump. The gun filter sits at the spray end and catches finer particles before the tip. Both protect the system, just at different points in the line.
