Steel Case Wiper | Polypac Hydraulic Seal Experts

Steel Case Wiper — Polypac

Overview

Polypac Steel Case Wipers are engineered to protect hydraulic cylinders from contaminants, extending seal life and system reliability. Combining a rigid steel case with precision elastomeric wiping lips, our wipers offer consistent scraping performance, low friction and excellent dimensional stability. Designed for heavy-duty and high-cycle applications, Steel Case Wipers are a cost-effective first line of defense for pumps, cylinders and mobile equipment.

Materials & Compatibility

We use a range of sealing compounds and fillers developed from our decades of sealing expertise, including NBR, FKM, EPDM, silicone and specialty PTFE blends. The steel case provides structural support while the tailored lip material ensures compatibility with hydraulic oils, greases and additive packages. Polypac’s material selection process balances abrasion resistance, elasticity and chemical compatibility to minimize wear and prevent leakage under varied temperatures and pressures.

Manufacturing & Quality

Manufactured in our advanced 8,000 m² production facility, each Steel Case Wiper undergoes precision molding, assembly and rigorous testing. Polypac integrates automated inspection and custom tooling to ensure concentricity and consistent lip geometry. Our collaborations with universities and research institutes, plus years of PTFE and elastomer development, guarantee products that meet industry standards and your custom specifications.

Applications & Benefits

Steel Case Wipers are ideal for construction, agricultural, hydraulic presses, and industrial machinery where contamination can accelerate seal failure. Benefits include improved service intervals, reduced maintenance costs, and enhanced system uptime. Their robust design resists extrusion, maintains wiper contact under misalignment, and performs reliably across a broad temperature range.
