Low Friction Piston Seal Solutions by Polypac

Low Friction Piston Seal Solutions by Polypac

Why choose Low Friction Piston Seal?

Polypac Low Friction Piston Seal designs minimize energy loss and heat generation while maximizing cycle life and stability. Ideal for high-speed, high-frequency, and low-pressure return systems, these seals reduce stick-slip and improve responsiveness across mobile and industrial hydraulic cylinders.

Advanced materials for reliable performance

We leverage decades of expertise in filled PTFE formulations—bronze-filled, carbon-filled, graphite-filled, MoS2-filled, and glass-filled PTFE—to deliver ultra-low friction sliding surfaces. Complementary elastomers such as NBR, FKM, silicone, EPDM, and FFKM are selected for sealing lip integrity, chemical resistance, and temperature tolerance, ensuring the Low Friction Piston Seal performs reliably under varied media and temperatures.

Precision manufacturing and testing

Polypac’s custom rubber ring and O-ring factory spans over 10,000 m2 with 8,000 m2 dedicated to production. Our advanced machining, molding, and testing equipment ensures dimensional accuracy and repeatable friction characteristics. Every Low Friction Piston Seal undergoes dynamic testing to validate wear, leakage rates, and friction torque before delivery.

Customization for special working conditions

From bespoke profiles and material blends to bonded assemblies and integrated backup rings, Polypac provides tailored Low Friction Piston Seal solutions for extreme pressure, abrasive environments, and vacuum or cryogenic applications. Collaborative R&D with universities and labs enables rapid development of seals that meet unique client specifications.

Applications and benefits

Our Low Friction Piston Seal products are deployed in construction equipment, hydraulic presses, aerospace actuators, and renewable energy systems. Benefits include lower power consumption, smoother control, extended maintenance intervals, and reduced heat buildup—delivering measurable lifetime cost savings.

FAQ:

What is the difference between a static seal and a dynamic seal?

A Static Seal is used between two surfaces that do not move relative to each other (e.g., pipe flanges, end caps). O-rings and gaskets are common static seals. A Dynamic Seal is used between surfaces that do move (e.g., piston and cylinder, rotating shaft). Rod seals, piston seals, and rotary shaft seals are designed for this purpose.

How do I choose the right material for my sealing application?

Material selection depends on four key factors: Media: What fluid or gas will the seal contact? (e.g., petroleum oil, water, chemicals, steam) Temperature: What is the minimum and maximum operating temperature? Pressure: What is the system's operating pressure? Are there pressure spikes? Application: Is it a static, dynamic, or rotary seal? Example: NBR (Buna-N) is excellent for standard hydraulic oil, while FKM (Viton®) is needed for high temperatures or aggressive chemicals.

What is the purpose of the metal spring in a rotary shaft seal?

The garter spring in a shaft seal (e.g., FSKR, SPGO types) provides a constant radial force on the sealing lip. This ensures consistent contact with the rotating shaft, compensating for minor wear, eccentricity, and vibration to prevent lubricant leakage.

How can I prevent seal damage during installation?

Use Tools: Always use dedicated installation tools (e.g., picks, cones, guides). Lubricate: Always lubricate the seal and the contact surface. Protect Sharp Edges: Cover sharp threads and edges with tape or use an installation sleeve. Check the Groove: Ensure the installation groove is clean, deburred, and undamaged.
