Common Questions
- What mesh or screen size does it come with?
- LF777M3-20 2 ships with a 20 mesh 304 Stainless Steel screen (20 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 20 mesh. Finer screens catch smaller particles but clog faster and cost more pressure drop, so size the screen to the debris you actually have.
- Can I use this on steam?
- Yes. LF777M3-20 2 is rated 125 psi WSP on steam, which is a separate and much lower limit than its 400 psi WOG (cold water, oil, gas) rating. Do not size steam service off the WOG number.
- Does it have a blowoff / blowdown port?
- No. This model has a solid retainer cap, so cleaning means removing the cap and lifting out the screen. If you want to blow the strainer down in place, order the tapped-cap version of this body instead.
- What is the "seat material" on a strainer?
- A strainer has no seat -- nothing closes against anything. The EPDM 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.
