3-inch FNPT Y Strainer

The Zoro Select 20H630 Y strainer installs in a 3-inch FNPT pipeline to remove debris from water, oil or gas service. Its cast-iron body and stainless-steel perforated screen handle 400 psi at 100°F and 150°F. The unit measures 10 inches long and 6 inches high with a 1-1/2-inch blow-off port for cleaning.

Who it suits and who it does not

Plumbing contractors and maintenance teams needing a flanged-free, female-threaded strainer for 3-inch iron or steel pipe will find the connection direct and the screen easy to service. Systems that require a finer mesh than 0.0625-inch perforations or a different pressure class should look elsewhere.

Pressure rating decides fit

The 400 psi maximum working pressure at both 100°F and 150°F is the single figure that determines whether this strainer matches the design conditions of the piping system.

Questions about this item

How do I install the 3" FNPT Y strainer and which orientation step is often missed?

Thread the cast-iron body onto 3" NPT pipe using the female ports; the screen must face downward so debris collects in the 1 1/2" blow-off port for easy flushing.

What ongoing maintenance does the stainless perforated screen with 0.0625" holes require?

Periodically open the 1 1/2" blow-off valve to purge trapped particles; remove and clean the screen if flow drops, then reinstall with the same downward orientation.

At what temperature does the 400 psi pressure rating begin to derate under sustained use?

The 400 psi rating holds at 100 °F; at 150 °F the allowable pressure decreases, so sustained high-temperature service is the first limiting factor.
