Hello! Welcome to the official website of Xinxiang Xingda Filter Co., Ltd.!
High-Precision Industrial Hydraulic Filter Element | Direct Factory Replacement
Tired of Filters That Let You Down Mid-Job?
If you’ve ever had a cheap filter clog after 200 hours, shut down your excavator on a mine site, or ruin a hydraulic pump with unfiltered oil, you know exactly what we’re solving here. This isn’t a generic “one-size-fits-all” filter—we built it for the heavy gear that runs 24/7 in mines, construction yards, power plants, and offshore rigs. No marketing fluff, just real test data and build quality that’s stood up to the harshest conditions on the planet.
The Specs That Actually Move the Needle
We don’t just list numbers—we tell you what they mean for your equipment and your bottom line.
| Parameter | Our Filter Spec | What This Does For You |
|---|---|---|
| Filter Media | 316/304 stainless steel material | 3x more dirt-holding capacity than standard paper filters, so you change filters half as often |
| Filtration Rating | 1–25μm absolute (βₓ ≥ 200, tested to ISO 16889) | 99.9% of particles ≥ rated size get trapped. That means your hydraulic oil stays 10x cleaner than with cheap 10μm nominal filters, cutting pump wear by 70% |
| Max Operating Pressure | Up to 420 bar (6090 psi) | Handles the pressure spikes in heavy loaders and excavators without blowing out or failing |
| Collapse Pressure | ≥ 10 bar (145 psi) | No media collapse during cold starts or high-flow surges—no unfiltered oil getting to your system |
| Operating Temp Range | -30°C to +120°C (-22°F to 252°F) | Works flawlessly in Arctic mining (-20°F) and desert construction (120°F) without brittling or melting |
| Flow Rate | 100–600 L/min (26–158 gpm) | Direct drop-in fit for OEM hydraulic systems, no modifications needed |
| Dirt Holding Capacity | ≥ 150 g/m² (tested to ISO 19438) | 2x longer service life than competing filters. For a 200-ton excavator, that’s 1800 hours vs. 800 hours for OEM |
| Seal Material | NBR (standard) / FKM (optional) | Resists degradation from hydraulic, gear, and synthetic fluids—no leaks, no replacements mid-job |
| End Caps | CNC-machined 6061-T6 aluminum | Corrosion-proof, precision fit for zero-leak installation, no more cross-threading or loose connections |
| Support Layers | Spiral-connected central tube support layer | Stops the filter media from deforming under high flow, keeping filtration consistent for the full service life |
Built for the Jobs That Break Cheap Filters
1. 99.9% Filtration That Actually Lasts
We use a gradient pore glass fiber media: bigger pores on the outside catch large debris, smaller pores on the inside trap fine particles. This isn’t just marketing—we’ve tested it side-by-side with OEM and budget filters:
In a 200-ton excavator working a Chinese mine, our filter hit the 0.5 bar pressure drop threshold at 1800 hours. The OEM filter hit it at 800 hours, and a budget competitor failed at 400 hours.
At 400 L/min flow, our filter only has a 0.18 bar pressure drop, vs. 0.32 bar for OEM. That cuts your hydraulic system’s energy use by 12%—real savings on fuel and electricity.
After 1000 hours at 120°C, our filter had 0% media delamination and 99.8% efficiency retention. A budget filter lost 15% efficiency and started leaking.
2. Industrial-Grade Build That Doesn’t Cut Corners
Precision pleating: 4mm pleat spacing maximizes filtration area (up to 0.8 m² per element) while keeping pressure drop low. No overcrowded pleats that clog early.
Optional calibrated bypass valve: 0.35 bar (5 psi) opening pressure, 100% leak-tight closure. For critical systems that can’t shut down, it only opens when the filter is fully clogged—no unfiltered oil bypassing during normal operation.
High-temp adhesive bonding: Withstands 120°C continuous use without delaminating. Cheap filters use glue that melts in hot environments, leading to catastrophic failure.
Stainless steel inner/outer mesh: Prevents media collapse, even at max pressure. No more filter media blowing through and damaging your pump.
3. Direct OEM Replacement, No Compromises
This filter is a 1:1 drop-in replacement for OEM filters from Caterpillar, Komatsu, Volvo, Hitachi, and more. We match the exact dimensions, flow rate, and pressure rating of your original filter—so you get the same performance, at 30-50% lower cost.
Where This Filter Performs Best
We’ve got thousands of these filters running in the field, in:
Construction: Excavators, bulldozers, wheel loaders, mobile cranes
Industrial Hydraulics: Hydraulic power units (HPUs), press machines, injection molding, steel mill equipment
Power Generation: Wind turbine hydraulic systems, gas turbine lube oil systems
Mining & Oil & Gas: Offshore drilling rigs, mining haul trucks, wellhead equipment
Marine & Offshore: Ship hydraulic systems, offshore platform control units
Why Buy From Us, Not OEM or Cheap Imports?

|---|---|---|---|
| Price | 30–50% lower than OEM | 2–3x our price | Similar, but 50% shorter life |
| Filtration Efficiency | 99.9% absolute (tested) | 99.9% absolute (batch tested) | 90% nominal (unreliable) |
| Service Life | 1800 hours (field tested) | 800 hours | 400 hours |
| Lead Time | 3–7 days for standard sizes | 2–4 weeks | 7–14 days |
