Polypac Press Machine Piston Seal — Reliable Sealing for High-Load Presses

Polypac Press Machine Piston Seal — Overview

Polypac’s Press Machine Piston Seal is designed for hydraulic presses and heavy-duty piston applications. Built with industry-leading materials and strict quality control, it delivers reliable sealing, reduced leakage, and longer service life. Backed by Polypac’s 10,000+ m² manufacturing base and advanced testing equipment, this seal is ideal for demanding production environments.

Why choose Polypac piston seals?

• High durability: Made from proven compounds including filled PTFE options for wear resistance.
• Low friction: Smooth operation reduces heat and energy loss, improving machine efficiency.
• Leak-tight performance: Optimized profile and material selection minimize oil leakage under high pressure.
• Customizable: Available in various materials like NBR, FKM, EPDM, silicone, and FFKM for specific working conditions.

Applications

Designed for press machines, metal forming equipment, hydraulic presses, and other high-load piston systems where stable sealing and minimal maintenance are critical.

Features and Benefits

Polypac leverages years of research and partnerships with universities to deliver seals that balance toughness and flexibility. Key benefits include:
