Heavy-Duty Construction
This dust seal 100*115*4 is manufactured using polyurethane or NBR lip compound for abrasion resistance and flexibility at operating temperatures. Spring-loaded lip maintains contact pressure as the seal wears. Compatible with standard excavator 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.
