Spring-energized seal 103A

polymercircularfor crawlers

Overview
Spring-energized polymer seal 103A features a polymer jacket with an internal ribbon or helical spring energizer. Designed for static and low-speed sealing, it provides controlled leakage performance under high system pressures and at cryogenic temperatures.

Design & Function

• Ribbon or helical (spring-energized) energizer retained inside a shaped polymer jacket
• Jacket geometry secures the energizer and forms the sealing contact surface
• Engineered for static face seals and applications with low relative motion
• Material options available to match chemical compatibility and temperature requirements

Typical applications

• On/off valves in the energy sector, including custom seals for gate and ball valves
• Subsea ball and gate valves requiring reliable sealing at depth
• Aerospace anti-blowout seals for rocket engine check valves and main fuel valves
• Static face sealing in precision-fit gland and closed-groove assemblies

Installation & Support
Suitable for precision-fit gland configurations and closed-groove assemblies; designed to perform in demanding conditions including cryogenic temperatures and high-pressure environments. Engineering support available for material selection and custom sizing.
