Our poly filter housings are manufactured from the highest
quality 100% polypropylene acrylic styrene (for clear housings).
Leak-proof sealing is accomplished by compression against a
top seated EPDM O-ring located in the housing’s sump. Thick
wall and added ribs make the housings ideal for a wide range
of applications. Polypropylene construction provides excel-
lent chemical resistance in most installations environments.
Housings supplied with and without pressure relief valves. See
specifications table for pressure and temperature ratings.
