Watts acquired Flowmatic in November 2003. Consequently, all Flowmatic filters, water filter systems, filter housings and components are now listed under our Watts category.

Watts Water Filter Housing

Watts water filter housings produce high-quality drinking water for your office or business. Stainless steel filter housings are designed for a number of applications and can handle high temperatures, high pressure, and aggressive chemicals. Non-metallic filter housings are a great alternative to the stainless steel options because they ensure chemical compatibility and sea water use and generally cost less.

Watts Marine Fittings

Watts marine fittings include thru-hulls, seacocks, ball valves, hose bibs, and supercoil hoses. Many of the marine fittings can be used above or below the water line.

  • • Pipe fittings made of 85-5-5-5 naval bronze
  • • Pipe fittings in sizes 1/2"" - 3""
  • • Pipe fittings to use above or below the water line
