Hydraulic Oil Filter Elements – Models HY19296 · SH51500 · SH51500V

Three replacement hydraulic oil filter elements for return-line, pressure-line, and offline kidney-loop filtration on industrial power units, mobile machinery, and stationary equipment. HY19296 and SH51500 are documented as cross-interchangeable hydraulic cartridges; SH51500V follows the same family with a variant configuration. All three are supplied as configurable replacements — micron grade, media, end caps, seals, and dimensional envelope are selected to match the host filter housing and fluid type. Confirm outer diameter, inner diameter, overall length, and end-cap pattern against the existing element before ordering.

Key Features

• Configurable media: glass-fiber microglass (high β-ratio, absolute-rated), synthetic/cellulose fibre, or stainless steel wire mesh (cleanable)

• Micron range: 1 / 3 / 5 / 10 / 20 / 25 / 40 / 100 / 150 / 200 µm

• β-ratio verification: ISO 16889 multipass — e.g. β₁₀ ≥ 200 (99.5 %), β₁₀ ≥ 1000 (99.9 %) on microglass grades

• Seals: NBR standard for mineral oil; FKM for phosphate-ester, water-glycol, high-temperature, or aggressive synthetics

• Temperature: microglass typically -20 °C to +135 °C; verify per media and seal

• Flow direction: Outside → Inside unless the host housing specifies otherwise

• Disposable microglass/synthetic; stainless mesh washable and reusable

Technical Specifications

HY19296↔SH51500 interchange and hydraulic application referenced via cross-supply data ; SH51500 glass-fibre/synthetic, 10–30 µm hydraulic, 20–50 L/min, 1.6–3.5 MPa listed on one supplier build . SH51500V exact envelope not standardized in open data — verify before order.

Application Guidance

Select micron grade by circuit position:

• 1–5 µm — servo and proportional valves, high-pressure piston pumps

• 5–10 µm — general pressure-line protection on 70–210 bar systems

• 10–25 µm — return-line and vane/gear-pump circuits

• 25–200 µm — suction pre-filtration and coarse guard

Use β-rating, not nominal micron alone: β₁₀ ≥ 75 suits general industrial hydraulics; β₁₀ ≥ 200 suits servo/proportional valves; β₁₀ ≥ 1000 suits critical servo or turbine control .

Fluid Compatibility

• Mineral hydraulic oil (HH/HL/HM/HV) — NBR seals

• Water-glycol (HFC) — confirm media; FKM recommended

• Phosphate-ester (HFDR) — FKM mandatory; verify media binder

• Biodegradable ester — confirm media and seal before use

Installation & Service

1. Depressurize the housing to zero; isolate from the circuit.

2. Remove the spent element; inspect media for metal debris (pump/valve wear indicator).

3. Clean housing, bypass spring, and seal grooves.

4. Seat the new element with correct flow direction; renew all O-rings/gaskets.

5. Close and torque fasteners evenly; bleed air.

6. Replace at clogging-indicator setpoint, when ΔP reaches ~75 % of bypass, or per fluid-analysis/ISO 4406 trend — not by calendar alone .

7. Microglass/synthetic are disposable; stainless mesh may be cleaned and reused.

Ordering

Specify model (HY19296 / SH51500 / SH51500V) plus: host machine and filter-housing model; circuit position; micron and β-target (e.g. β₁₀ ≥ 200); media type; collapse/burst pressure; seal material; fluid type; and old-element OD × ID × length plus end-cap/thread pattern. Supply a photo or drawing for cross-reference; non-standard sizes are configurable.

Nominal data only. HY19296 and SH51500 are cross-listed hydraulic cartridges ; SH51500 listed builds use glass-fibre/synthetic media, 10–30 µm hydraulic accuracy, 20–50 L/min, 1.6–3.5 MPa . SH51500V envelope to be confirmed per housing. Performance depends on verified β-ratio (ISO 16889), collapse pressure, and media/seal compatibility — dimensional match alone is not a functional equivalent .
