| Features:
• Meets HF4 automotive standard
• Non-welded housing design reduces stress concentrations and prevents fatigue failure.
• Inlet/Outlet port options include SAE straight thread O-ring boss, SAE flange code 62 and code 61 (optional) BSPP and subplate
mounting to allow easy installation without costly adapters.
• O-ring seals are used to provide positive, reliable sealing. A choice of O-ring materials (nitrile rubber or fluorocarbon
elastomer) provides compatibility with petroleum oils, synthetic fluids, water-glycols, oil/water emulsions, and high water based
fluids.
• The element filter housing is permanently mounted above the filter head for easy top access and minimal clearance to remove
elements for replacement.
• Clogging indicators are actuated by differential pressure and have no external dynamic seal. High reliability is achieved and
magnetic indicator actuation eliminates a potential leak point.
• A poppet type bypass valve located in filter head base is mounted between the inlet and outlet port to provide positive
sealing during normal operation and fast response during cold starts and flow surges.
• Fatigue pressure rating equals maximum allowable working pressure rating.
