Why Use a MicroGuard Steering Filter?

Keeping steering fluid clean is essential to prolong the life of pumps, racks, and valves. Contaminated fluid is the leading cause of premature steering system failure.

Contaminant Protection

Filtration

Removes particles, metal shavings, rubber dust, and sludge to protect pumps, seals, and racks from abrasive wear.

Fluid Clarity & Longevity

System Health

Maintains fluid cleanliness to reduce oxidation, foaming, varnish formation, and temperature spikes in hydraulic circuits.

Extended Service Life

Durability

High dirt-holding capacity with reinforced pleats prevents premature saturation and extends change-out intervals.

Easy Maintenance

User Friendly

Standard OE thread/quick-connect design ensures direct replacement without modifications or special tools.

High Temperature Resistance

Performance

Engineered to operate in extreme under-hood conditions up to 135°C without media breakdown or seal leakage.

Steering Response

Control

Ensures smooth hydraulic flow, reducing noise, cavitation, and loss of steering assist during operation.

System Benefits

Protects steering pump, rack, and valves from abrasive and chemical damage
Maintains consistent hydraulic pressure for predictable steering response
Reduces steering effort and eliminates stiff steering issues
Minimizes pump noise, cavitation, and overheating
Extends the lifespan of expensive steering components

Multi-Layer Media Technology

Dual-stage filter media captures coarse contaminants in outer layers and micro-particles in inner layers, ensuring cleanliness down to 10 µm.
