Common Questions

What mesh or screen size does it come with?

P777-100-Z1 1/4 ships with a 100 mesh 304 Stainless Steel screen (100 openings per linear inch). The screen is called out by the number in the model code.

Can I get a finer or coarser screen?

Yes. Watts builds this body with a range of screens and encodes the choice in the model number, so a finer or coarser screen is a different part number rather than an accessory. This one is 100 mesh. Finer screens catch smaller particles but clog faster and cost more pressure drop, so size the screen to the debris you actually have.

Does it have a blowoff / blowdown port?

Yes. The retainer cap/cover is tapped for a blowoff connection, so you can flush accumulated debris by pulling the plug or piping a blowdown valve to it -- no need to break the strainer apart. The closure plug is included.

What is the "seat material" on a strainer?

A strainer has no seat -- nothing closes against anything. The Buna-N called out here is the retainer-cap seal (the gasket between the cap and the body), which is what limits the temperature and chemical compatibility of the closure.
