Basket Strainer for 1/2 Inch Pipe

The Mueller Steam Specialty basket strainer removes particulates from fluid lines in residential or light-commercial plumbing. Its cast stainless-steel body and Buna-N gasket suit water filtration duties where corrosion resistance matters. The unit is supplied new and ready for inline installation.

Verify Threads Pressure and Temperature

Confirm the existing piping uses 1/2 inch FNPT threads on both sides so the strainer seats without adapters. System pressure must not exceed 275 psi at 100 degrees Fahrenheit and fluid temperature must stay at or below that same 100 degree limit. The 31/500 inch mesh screen handles particulate removal only.

Steady Flow Within Rated Limits

Under continuous operation the housing maintains its seal at the full 275 psi rating while the fine mesh traps debris without rapid clogging. Pressure drop remains stable as long as the screen is cleaned before buildup restricts flow. The cast stainless construction resists thermal cycling at the maximum rated temperature.
