The Arkay FH-5 Blue Filter Housing for Cold Water is constructed of reinforced polypropylene with a 3/4" FPT pipe connection.
The FH-5's leak-proof sealing is accomplished by a cap compression against a top seated Buna-N O-Ring in the sump.
The Acme square thread closure allows for years of cartridge change-outs without failure. All caps come with four mounting bosses for ridged "L" bracket mounting.
The polypropylene construction has excellent chemical resistance for long life. It is rated at 125°F, and up to 125 PSI.
