Nemato National LineTM strainers are constructed of food grade Fiberglass Reinforced Isophthalic or Vinylester Resin (F.R.P.), PVC and stainless steel material. The strainers are totally non-corrosive and have a high gloss gel-coat finish with UV protection. The strainers are designed for working pressures of 30 P.S.I.G. or 65 P.S.I.G. and a vacuum service of 20" of mercury.

All National strainer designs come with integrally molded influent/ effluent 2" to 14" vanstone flange connections, F.R.P./ clear acrylic cover, hinged lid fastening hardware and drain/ vent plugs. The strainers come in three body diameters (6", 10", 16") with straight or eccentric reducing pipe configurations. NSF International certifies all National 30 P.S.I.G. & 65 P.S.I.G. Strainers to ANSI/ NSF Standard 50 for both pool and spa applications.
