Product Description

Overview

Polypac Chemical Resistant Piston Seal is designed for hydraulic and industrial applications where aggressive fluids, high temperature swings, and harsh environments challenge ordinary seals. Built from advanced materials and produced in our modern facility, this piston seal offers lasting performance with minimal maintenance.

Why choose Polypac Chemical Resistant Piston Seal?

Outstanding chemical resistance: available in PTFE variants and high-performance elastomers (FFKM, FKM) to withstand acids, solvents, and hydraulic fluids.
Low friction and smooth operation: engineered profiles reduce wear and improve energy efficiency.
Long service life: precision molding and advanced material fills (carbon, graphite, MoS₂) extend seal lifetime under cyclic loads.
Custom solutions: tailored sizes and compound blends to suit special working conditions.
Reliable quality: manufactured in an 8,000 m² production space with industry-leading testing equipment.

Key features

- Multiple material options for specific chemical compatibility and temperature ranges.
- Tight dimensional control for leak-free performance.
- Low extrusion risk in high-pressure systems.
- Compatible with standard piston housings and custom designs.

Applications

Ideal for hydraulic cylinders, chemical pumps, mobile equipment, and industrial machinery exposed to corrosive media or extreme environments.

Question you may concern

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.

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.

When should I use a spring-energized seal instead of a standard elastomeric seal?

Consider a spring-energized seal (e.g., GSF, SPN types) for demanding applications involving: Extreme Temperatures (below -30°C or above +200°C) Aggressive Chemicals that elastomers can't handle Very Low Leakage or "Zero Leakage" requirements Poor Lubricity or dry running conditions The internal spring maintains constant sealing force, compensating for wear and system variables.

What does "AS568" mean?

AS568 is the Aerospace Standard that defines the dimensions for over 360 standard O-ring sizes. It is the most widely accepted sizing system in North America and globally. An AS568 number (e.g., AS568-214) specifies a precise inside diameter and cross-section.
