Common Questions

What mesh or screen size does it come with?

843H 6 ships with a 10 mesh stainless steel screen (10 openings per linear inch). 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.

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.
