Replacing only the rod seal and leaving the failed dust seal in place guarantees a callback — the dust seal wipes the rod clean every stroke, and without it, contamination destroys the new rod seal in days. This dust seal vay 40*55*4 provides OEM-matched lip geometry for correct dust exclusion.

Why Choose This Dust Seal VAY 40*55*4
– OEM-matched lip profile and spring tension for correct rod contact across the full stroke
– Housing bore diameter matched to OEM cylinder rod gland for direct press-fit
– Correct rod diameter range — fits without excessive compression or clearance

Heavy-Duty Construction
This dust seal vay 40*55*4 is manufactured using polyurethane lip for abrasion and wear resistance in dusty conditions. Spring-energised lip maintains consistent rod contact as the seal face wears. Compatible with mineral and biodegradable hydraulic fluid types. Designed to withstand vibration, impact loads, and harsh operating environments commonly found in construction, quarry, mining, and earthmoving applications. Precision manufacturing helps ensure correct fitment and long service life.

Applications
Suitable for a wide range of heavy equipment and undercarriage systems including:
– Excavators
– Dozers
– Loaders
– Track roller assemblies
– Earthmoving machinery undercarriage components

Maintenance Recommendations
– Always fit dust seal and rod seal together — partial kit replacements waste labour cost
– Check rod surface finish before fitting; polish out any score marks with 600-grit
– Use seal driver of correct OD — hammering distorts the housing bore
