Polypac’s Heavy Duty Connection Ring combines decades of sealing expertise with advanced materials science to solve the toughest connection challenges. Designed for heavy-duty hydraulic and oil systems, this product ensures stable, leak-free joints under high pressure, vibration, and temperature fluctuations. Backed by our history in PTFE-filled seals and multi-material O-rings, the Heavy Duty Connection Ring is an essential component for critical industrial applications.

High Quality Materials and Compatibility

We offer Heavy Duty Connection Ring options in a wide range of elastomers and plastics, including NBR, FKM, EPDM, silicone, FFKM, and filled PTFE variants (bronze, carbon, graphite, MoS₂, glass). Material selection is tailored to chemical exposure, temperature range, and mechanical loads to guarantee long service life and minimal maintenance.

Precision Manufacturing and Capacity

Our custom rubber ring and O-ring factory spans over 10,000 m² with 8,000 m² of dedicated production space. Using industry-leading production and testing equipment, every Heavy Duty Connection Ring is produced to tight tolerances and inspected to strict quality standards, delivering consistent performance for OEMs and end users alike.

Customized Solutions for Special Conditions

Polypac specializes in customized sealing solutions for special working conditions. Whether you need modified geometries, compound blends, or hybrid PTFE-elastomer constructions, our R&D collaborations with universities and research institutions enable rapid prototyping and application-specific optimization.

Quality Assurance and Testing

Founded in 2008, Polypac applies rigorous testing protocols to every batch. From material certification to endurance and leakage testing, we document performance metrics so you can confidently specify the Heavy Duty Connection Ring in safety-critical systems.

Applications and Benefits

Ideal for heavy machinery, hydraulic cylinders, high-pressure pumps, and industrial connectors, the Heavy Duty Connection Ring reduces downtime, minimizes leak risk, and extends component life. Our global supply capability and competitive lead times make Polypac the partner of choice for demanding sealing requirements.

How to Order

FAQ:
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.

Can I reuse a seal?

We strongly recommend never reusing seals. Once compressed and used, a seal takes a "set" and its elastic properties are degraded. Reusing it almost always results in a leak. Always install a new seal during any maintenance or repair.

Why did my O-ring fail prematurely?

Common causes of O-ring failure include: Chemical Incompatibility: Swelling, softening, or cracking due to fluid exposure. Improper Sizing: Using an incorrect size leads to over-compression or inadequate sealing force. Abrasion: Wear and tear from rough surface finishes or contaminated fluid. Extrusion: The seal is forced into the gap between metal parts under high pressure. Installation Damage: Nicks, cuts, or twists during assembly.

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.
