Hydraulic Oil Filter Element – Product Detail

These hydraulic oil filter elements (P0540016‑00073 / Р1400009‑00770) are designed for pressure‑line or return‑line filtration in stationary industrial hydraulic systems, compressor lube circuits, gearbox circulation loops, and process‑oil applications. They remove abrasive particles and oxidation by‑products from mineral or synthetic oils, protecting pumps, valves, bearings, and actuators.

Construction

Both elements use a pleated glass‑microfiber media (resin‑impregnated, β₁₀ ≥ 200) supported by a perforated steel center tube and an outer galvanised‑steel retainer cage. End caps are epoxy‑bonded steel; the seal groove accepts either nitrile (NBR) or fluorocarbon (FKM) O‑rings depending on the variant. A bypass valve (typically 1.0–1.5 bar) is integrated in the mating head, not the element. Collapse pressure rating is 21 bar standard (31 bar wire‑back option available on request).

Technical Comparison

The two elements have identical dimensions, media grade, and collapse rating; the primary difference is seal polymer and thread standard. P0540016‑00073 (FKM) mates with DIN‑style heads (common in European hydraulic packs), while Р1400009‑00770 (NBR) mates with GOST/DIN hybrid heads (found on CIS‑origin equipment).

Applications

• Pressure or return legs of industrial hydraulic power packs (presses, cranes, gate hoists)

  
  

• Lube oil circuits of rotary screw compressors (mineral ISO VG 46/68 or PAO synthetics)

  
  

• Circulation loops in gearboxes and bearing housings

  
  

• Offline kidney‑loop filtration for transformer oil or process fluids

  
  

• Retrofit replacement for legacy European or CIS‑design equipment

  
  

Selection Guidance

Choose P0540016‑00073 (FKM) for synthetic oils (PAO, PAG), high‑temperature circuits (up to 100°C), or when biodiesel / HVO blends are present – FKM resists swelling and embrittlement that NBR suffers in aggressive fluids. Choose Р1400009‑00770 (NBR) for standard mineral hydraulic oils, diesel‑engine lube, and compressor oils where operating temperature stays below 80°C and the head uses GOST/DIN hybrid threading.

Maintenance

Replace when differential pressure reaches 1.5–2.0 bar or per OEM schedule (typically 2 000–4 000 operating hours for hydraulic loops, 500–1 000 hours for engine lube). Always replace the O‑ring with the same polymer as the element. Store in a cool, dry environment away from UV and ozone.
