Fit & Selection Guidance

Confirm your sprayer’s inlet thread is ¾". If your model specifies a different inlet size, choose the correct strainer size accordingly. When in doubt, reference your sprayer’s parts manual or contact support with the model and serial number.


Installation & Care

  1. Shut down and fully depressurize the sprayer.
  2. Unthread the old strainer; clean the inlet seat if needed.
  3. Thread in 183770 by hand; snug with the correct wrench (do not overtighten).
  4. Prime, check for leaks, and verify smooth flow.

Maintenance: Inspect and rinse the screen regularly. Replace if mesh is torn, crushed, or heavily clogged.


Frequently Asked Questions

 

No. 183770 is for ¾" inlets. If your manual specifies 1", select the matching 1" strainer for proper sealing and flow.

Thread it in by hand, then snug with a wrench—firm, but not overtight. Over-tightening can damage threads or the housing.

Yes. The inlet strainer is the first stage. Inline gun filters and tip strainers add finer filtration closer to the spray tip.

Rinse the screen whenever you flush or change materials. Inspect weekly; replace if bent, torn, or persistently clogged.

It’s not recommended. Running without a strainer increases the risk of pump damage and frequent clogs downstream.
