The HV3R1SC4RBB1C03 unit is part of the Vickers Hydraulic Accessories series produced by Vickers for use in hydraulic automation circuits where dependable fluid conditioning is required. It has an assembly length of 207 mm (8.15 in), allowing installation in compact return or offline lines. A dry weight of 2.3 kg (5.1 lb) simplifies manual removal during service. The aluminum head keeps overall mass low, while a carbon-steel bowl and matching carbon-steel collar provide pressure resistance and secure clamping of the internal element. A Buna-N seal is fitted at the joint to prevent external leakage. Connection to the system is made through a 1.625-12 UN SAE-20 straight-thread port, and the housing is sized to pass up to 160 L/min (42 US gpm) without undue restriction.
The accessory tolerates operating pressures up to 50 bar (725 psi) so it can function in low-pressure sections of a hydraulic system. An internal bypass valve cracks at 3 bar (43 psi) differential to maintain flow if the element becomes obstructed. An electrical Brad Harrison indicator signals at 2 bar (30 psi) to prompt timely element replacement before bypass occurs. The element itself is built to a low-collapse specification with a 17 bar strength rating, ensuring it stays intact during transients. When serviced properly, the assembly supports an oil cleanliness level of 16/14/12 or better to protect downstream components. Fluid compatibility covers petroleum oils as well as oil-in-water and water-in-oil emulsions, widening its application range across industrial hydraulic machinery.
