Product Description

Product Overview

The Polypac DC12 Seal is a high-performance hydraulic and oil seal designed for demanding industrial applications. Built with attention to material selection and precision manufacturing, the DC12 delivers stable sealing performance, low friction and long service life. It is suitable for mobile equipment, industrial hydraulics and other systems that require dependable fluid retention under pressure and movement.

Key Features

Advanced Materials

DC12 seals are available in a range of materials, including filled PTFE options and common elastomers such as NBR, FKM, EPDM and silicone. This allows you to match the seal to working temperatures, fluids and wear conditions for optimal performance.

Low Friction & High Wear Resistance

Designed to minimize friction, the DC12 reduces heat and energy loss while maintaining a tight seal. The use of reinforced PTFE or specialty elastomers improves abrasion resistance and extends service intervals.

Customizable for Special Conditions

Polypac provides tailored solutions for unusual or harsh environments. Whether you need specific dimensions, material blends, or enhanced chemical resistance, we can develop DC12 variants to meet your needs.

Q&A

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 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.

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.
