Series 77F-SS, 77G-SS Stainless Steel Strainers are light-
weight, fabricated wye-pattern strainers designed to remove
dirt and other debris from fluid systems. A simple cover and
coupling design permits easy cleaning or replacement of
the screen.
Features
• 304 stainless steel body exhibits superior corrosion resis-
tance compared to cast iron; eliminates casting porosity
problems; complies with NSF 61 and FDA requirements
• 50% lighter than cast iron strainers, reducing handling and
installation equipment costs
• Lead Free construction complies with California Prop. 65
and proposed Federal Government lead-free standards
• Single, two-bolt, grooved style cover provides quick and
easy access, saving disassembly/assembly time
• Screen retainer cover is tapped for strainer clean out
by opening a blow-off valve or removing the standardly
furnished closure plug
