The HF4P1SD4RBB6C10 accessory belongs to the Vickers Hydraulic Accessories series and is manufactured by Vickers to protect high-pressure circuits from particulate contamination. The complete assembly measures 685.3 mm (27.0 in) in length, allowing it to sit inline with standard reservoir-to-actuator plumbing. It sustains continuous operation at 345 bar (5000 psi), which suits demanding mobile and industrial power units. A rated flow of 379 L/min (100 USgpm) enables the element to support large displacement pumps without excessive pressure loss, while 1.875-12 UN SAE-24 port threads match 1.5 in tube connections for straightforward piping. The filter media is graded at 10 µm to capture fine particles, and a βx(c) value of 1000 shows that it removes 99.9 % of contaminants at the stated size. When differential pressure reaches 2.9 bar (43 psi), an internal bypass opens to keep oil moving and prevent cavitation. The unit is specified to help system fluid reach ISO 4406 20/18/15 cleanliness levels, reducing valve wear and extending component life.
The housing withstands cyclic loads up to 240 bar (3500 psi) so it can handle pressure spikes created by rapid actuator reversals, and the element carries a 10 bar (150 psi) collapse rating to resist deformation when clogged. A carbon-steel bowl resists impact and abrasion, while the ductile-iron head provides high tensile strength for secure manifold mounting. Buna-N seals are fitted to maintain a leak-tight barrier with common petroleum-based fluids. A Brad Harrison electrical connector is supplied for the clogging indicator, and the indicator trips at a 2 bar (30 psi) setting to prompt timely element replacement. The assembly operates reliably between -26 °C and +121 °C (-15 °F to +250 °F), covering cold-start conditions and elevated reservoir temperatures encountered in continuous duty machines.
