Product Description

Product Description

Introducing the Spring Energized PTFE Seal, an ingeniously designed sealing marvel that blends spring-energized, pressure-assisted mechanics to deliver unmatched performance. This high-precision sealing solution features a meticulously crafted PTFE-or alternative polymer-jacket that partially encapsulates a corrosion-resistant metal spring energizer, ensuring superior durability and reliability.

Our PTFE jackets are expertly engineered and precision-machined, incorporating PTFE composites and other high-performance polymers. These seals operate flawlessly across a vast temperature range, from cryogenic conditions up to 250°C, and remain chemically inert in almost all environments. Select variants are also suitable for hygienic, sanitary applications.

Material
Our seals are crafted from PTFE filled with a variety of materials such as bronze, glass, graphite, carbon, and more, each selected to enhance performance for specific applications.

Application Example
Ideal for Radial Seals in Static Service, offering exceptional sealing efficacy.
Perfect for Radial Seals in Reciprocating Motion, ensuring dynamic performance.
Designed for Radial Seals in Rotary Motion, maintaining integrity under rotation.
Applicable for Inside Face Seals in both Static and Rotary Service.
Suitable for Outside Face Seals in Static and Rotary Service.

Section Structure
Our seals feature a symmetric design, accommodating both Rod and Piston applications.

Spring Type:
Features the robust U-shaped spring (Type 400) for comprehensive sealing.
Equipped with a round wire spring (Type APS) for enhanced resilience.
Incorporates an O-shaped spring (Type 103) for optimal sealing efficiency.


Groove
Includes a Standard Heel Groove for secure placement.
Offers an Extended Heel Groove for specialized applications.
Provides a Flanged Heel Groove for added stability.

Size
Available in both imperial and metric sizes, accommodating all style requirements.
