High-Performance Hydraulic Oil Filter – Models SH63169 & SH74049

Engineered for demanding hydraulic circuits, these two filters cover complementary duties: SH63169 is a medium-pressure spin-on unit for pressure-line or off-return guarding, while SH74049 is a high-capacity return-line element built for continuous-duty mobile and stationary systems. Both use composite glass-fiber/cellulose media calibrated to ISO 16889 multi-pass performance, giving stable β-ratios and predictable element life under pulsed flow.

Key Features

• SH63169: spin-on canister, integrated bypass, no loose parts during service

  
  

• SH74049: inside-out flow element, high-collapse cage, large dirt-holding volume

  
  

• Nitrile (NBR) seals standard; FKM available for ester-based fluids

  
  

• Anti-drain back and bypass options configurable per model

  
  

Technical Specifications

Application Split

SH63169 – Medium-pressure loops on wheel loaders, telehandlers, skid steers, and compact excavators where a spin-on package simplifies field service. Also suitable as a protective guard filter on pump discharge when space is limited.

SH74049 – Large-tank return circuits on agricultural tractors, combine harvesters, municipal sweepers, and stationary power packs where flow peaks are high but line pressure in return is low. The 58-bar collapse rating allows it to survive reverse-pressure transients during cylinder dump.

Installation Notes

• SH63169: Pre-fill with clean hydraulic oil before spinning on to reduce startup starvation. Tighten by hand plus 3/4 turn; do not use straps on the canister. Replace when ΔP reaches 2.5 bar or per OEM interval.

  
  

• SH74049: Verify cage integrity and end-cap seating before closing the housing. Ensure flow direction arrow on the element matches system return flow (inside→out). Change-out at 2.5–3 bar ΔP; log hours for trending dirt-load.

  
  

Fluid Compatibility

Both models are qualified with:

• Mineral hydraulic oils (ISO HM/HV)

  
  

• Biodegradable esters (HEES/HETG) – use FKM seals on SH63169

  
  

• Water-glycol (HFC) – confirm seal choice

  
  

Quality & Testing

Each batch is verified to:

• ISO 16889 – multi-pass filtration efficiency & dirt capacity

  
  

• ISO 2941 – collapse/burst

  
  

• ISO 3968 – pressure-drop vs. flow

  
  

• ISO 2943 – media/fluid compatibility

  
  

Ordering

Quote "SH63169" or "SH74049" with required micron (10 / 20 / 25 µm optional), seal material, and bypass setting if non-standard. Interchange cross-references to common OEM part numbers available on request—specify your machine brand and OEM number when enquiring.

All values nominal; confirm against actual system pressure, flow peaks, and fluid before final selection.
