Large Clearance Rod Seal Solutions by Polypac

Product Overview

Polypac's Large Clearance Rod Seal offerings are engineered to deliver dependable sealing performance where traditional rod seals fail. Designed for rods with greater-than-standard clearances, these seals minimize leakage, reduce wear, and extend cylinder life across construction, mining, marine, and industrial hydraulic systems.

Key Features & Benefits

Our Large Clearance Rod Seal line combines tight tolerance geometry with advanced sealing materials to maintain pressure integrity and control contamination. Benefits include improved leakage control under axial movement, enhanced abrasion resistance, reduced maintenance intervals, and compatibility with a wide range of hydraulic fluids.

Materials & Technical Capabilities

Backed by decades of material science expertise, Polypac manufactures Large Clearance Rod Seals from PTFE variants (bronze-filled, carbon-filled, graphite PTFE, MoS₂-filled, glass-filled) and high-performance elastomers (NBR, FKM, EPDM, silicone, FFKM). Our 10,000+ m² facility uses state-of-the-art CNC machining and molding to ensure consistent geometry and material properties for demanding environments.

Customization & Quality Assurance

Polypac specializes in custom seal designs for special working conditions. We collaborate with universities and research institutions to optimize sealing profiles, durometers, and compound formulations. Every Large Clearance Rod Seal undergoes dimensional verification, material testing, and performance trials to meet ISO and client-specific standards.

Applications & Performance

Ideal for heavy-duty hydraulic cylinders with rod eccentricity, thermal expansion, or wear-induced gaps, our seals perform in construction equipment, hydraulic presses, offshore winches, and industrial actuators. The design prioritizes dirt exclusion, low friction, and long-term stability under cyclical loads.
