The Arkay FH-10 Blue Filter Housing for cold water is constructed of reinforced polypropylene with a 3/4" FPT pipe connection. 

The FH-10's  leak-proof sealing is accomplished by 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.
