3/4 in NPT Basket Strainer for Water Systems

The Mueller Steam Specialty 155M-N basket strainer filters debris from water lines in swimming pool and general plumbing applications. Its cast iron housing with NPT threads handles pressures up to 200 psi at 100 degrees F. The included 304 stainless steel screen uses a .06 in mesh to capture particles while maintaining a Cv flow factor of 140 gpm.

Pressure and Temperature Limits

This strainer operates between -20 degrees F and 150 degrees F, making it suitable for cold and hot water lines within that range. The Buna-N gasket and swing clamp cover seal against the rated 200 psi maximum pressure at 100 degrees F. Performance above 150 degrees F or beyond the 200 psi rating is not supported by the design.

Flow Capacity and Screening Headroom

With a Cv of 140 gpm, the unit comfortably handles high-volume water circulation typical of pool systems. The .06 in mesh screen provides fine filtration but will increase pressure drop as debris accumulates, requiring periodic cleaning. It is not suited for applications needing finer micron ratings or flow rates exceeding the stated Cv factor.
