Common Questions

What mesh or screen size does it come with?

3 FP-SK-77F-FDA-NRS ships with a 1/16" perforated 304 Stainless Steel screen. That is the standard screen Watts supplies for this body at this pipe size -- the screen size is not called out in the model number, so it varies by size across the series.

Can I use this on steam?

Yes. 3 FP-SK-77F-FDA-NRS is rated 125 psi WSP on steam, which is a separate and much lower limit than its 200 psi WOG (cold water, oil, gas) rating. Do not size steam service off the WOG number.

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.
