Hydac_Filter_HF4R

HF4R(S) Series
In-Tank Return Line / Suction Filters
100 PSI • Up to 120 GPM

Features

  • Designed to meet and comply with HF4 Automotive standard and SAE J2066 standard.
  • Inlet port options include SAE straight thread O-ring boss, SAE Flange, and NPT ports to allow easy installation without costly adapters.
  • O-ring seals are used to provide positive, reliable sealing. Choice of Nitrile, Fluoroelastomer or EPR O-ring material provides compatibility with petroleum oils, synthetic fluids, water-glycols, oil/water emulsions, and water base fluids.
  • In-tank design requires minimal space for installation.
  • Provision is made for an additional inlet port to allow two return lines to be connected to the same filter.
  • 9˝ filters include 1-1/2˝ hose barb outlet.
  • 18˝ and 27˝ filters include 1-1/2˝ threaded NPT outlet.
