Polypac — Manufacturing Equipment Seal Solutions
Industry-leading Manufacturing Equipment Seal Production
Polypac specializes in Manufacturing Equipment Seal production for hydraulic and oil sealing applications. With a custom rubber ring and O-ring factory over 10,000 square meters (8,000 m² production space), we combine high-capacity manufacturing with precision engineering. As an award-winning seal manufacturer and oil seal supplier, Polypac supports industrial OEMs with reliable sealing components engineered for performance and longevity.
Comprehensive Materials & Product Range
Our product portfolio began in 2008 with filled PTFE seals — bronze-filled, carbon-filled, graphite PTFE, MoS₂-filled and glass-filled PTFE — and has expanded to include elastomer O-rings and custom rubber rings. Available materials include NBR, FKM, silicone, EPDM and FFKM to meet diverse temperature, chemical and pressure requirements common to manufacturing equipment.
Customized Solutions for Special Working Conditions
Polypac delivers tailored Manufacturing Equipment Seal designs for demanding environments: high temperature, aggressive chemicals, vacuum, dynamic reciprocating and rotary applications. We provide material selection guidance, design optimization and bespoke sealing solutions to reduce downtime and extend service intervals for critical equipment.
Advanced Production & Rigorous Quality Assurance
Our production and testing equipment rank among the most advanced in the industry. Polypac maintains strict quality controls and collaborates with universities and research institutions to validate performance under real-world conditions. Every Manufacturing Equipment Seal undergoes dimensional, material and endurance testing to ensure predictable field performance.

Manufacturing Equipment Seal Display
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.
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.
How important is surface finish on the metal parts that contact the seal?
Extremely important. A rough surface will abrade and wear out the seal quickly, causing leaks. A finish that is too smooth can prevent a lubricating film from forming. A typical recommended surface finish for dynamic applications is 0.2 to 0.8 μm (8-32 μin) Ra.
