This Pentek 150235 1-1/2 in. #20 Big Blue filter housing with pressure relief is suitable for high-flow and heavy sediment applications. The sump is made of reinforced polypropylene for strength and resistance to chemicals, and the cap is made of high-flow polypropylene (HFPP) for stiffness. The cap has 1.5 in. female National Pipe Thread Taper (NPT) threaded input and output connections and a nitrile butadiene rubber (Buna-N) O-ring to ensure a watertight seal. A pressure relief button on the inlet side of the cap releases pressure in the housing for changing filter cartridges.
