2-1/2" FNPT Y Strainer for Pipeline Filtration

This 2-1/2 inch FNPT Y strainer installs in piping systems to remove debris and protect downstream equipment. The cast iron housing with stainless steel screen suits commercial, industrial and residential plumbing applications. It handles water, oil, gas and compatible fluids in new installations or maintenance replacements.

400 psi Working Pressure at 100 Degrees F

The strainer withstands 400 psi at 100 degrees F and remains rated at 150 degrees F for hot fluid service. This pressure rating is the primary specification that determines whether the valve matches your system design. Exceeding the rated pressure risks housing failure and screen damage.

Female NPT Ports with 1-1/2" Blow-Off Port

Both inlet and outlet use female NPT threads for direct connection to male-threaded pipe or fittings. The 1-1/2 inch blow-off port allows screen cleaning without removing the strainer from the line. The 0.0625 inch perforated stainless screen traps particles while maintaining flow. The cast iron body requires compatible thread sealant and support for the 9-1/4 inch length.

Questions about this item

What does the 400 psi pressure rating mean once the strainer is installed in a real piping system?

The strainer is rated for 400 psi at 100 °F and 150 °F, so it will hold that working pressure across normal hot-water temperatures without derating.

What connection standard do the FNPT ports use and what does it cap in practice?

Both ports are female NPT threads, so they mate with standard male NPT pipe fittings and seal on the taper without needing separate gaskets.

What physical space and mounting details does the 9-1/4 in length and 5-7/8 in height require?

The body measures 9-1/4 in long by 5-7/8 in high with a 1-1/2 in blow-off port, so allow that envelope plus wrench clearance for the FNPT unions.
