What is the Graco 235004 Inlet Strainer 3/4"?
The Graco 235004 Inlet Strainer (3/4")—also called a rock guard—is a pump-side screen that filters out debris before it enters the sprayer. By stopping contaminants at the inlet, it helps prevent premature pump wear, reduces tip clogs, and keeps your finish consistent on the job.
Key Benefits
- Pump protection: Screens out chunks/contaminants before they reach the fluid section.
- Fewer clogs: Helps maintain steady flow and spray pattern quality.
- Service friendly: Simple to remove, rinse, and reinstall between jobs.
- OEM fit: Made for Graco paint sprayers that accept a 3/4" inlet strainer.

Frequently Asked Questions
It fits many Graco models that use a 3/4" UNF inlet strainer, including the machines listed above (ST/STX, Ultra/Ultra Max Lo-Boy variants, ES series, etc.). If you’re unsure, match your inlet thread size or check your sprayer manual for “inlet strainer 3/4" UNF” compatibility.
It blocks debris before it reaches the pump, helping to minimize tip clogs, maintain consistent spray, and extend the life of your sprayer’s fluid section.
Inspect and rinse after each job or material change. Replace if the mesh is torn, crushed, or if persistent flow restriction continues after cleaning.
The strainer uses a stainless-steel mesh suited for typical architectural coatings. If you require a particular mesh rating for specialty materials, check your sprayer manual or contact support with your application details.
Confirm a snug fit on the 3/4" UNF inlet, avoid overtightening, and always start with clean paint and a clean bucket. Rinse the strainer thoroughly after use to prevent dried material from restricting flow.
