Precision sealing ring 400A

custom-madepistonrod

Overview
This spring-energized polymer seal uses a cantilever (V-spring) energizer and a PTFE jacket with flanged ends. It is designed for dynamic sealing tasks and delivers controlled friction and leakage performance at moderate pressures and temperatures, suitable for reciprocating and rotary/oscillating motion.

Key features

• Cantilever (V-spring) energizer for dynamic sealing
• PTFE jacket with end flanges for enhanced seating and retention
• Corrosion-resistant V-shaped spring energizer
• Stable friction and leakage control at moderate pressures/temperatures
• Compatible with reciprocating (linear) and rotary/oscillating motion

Typical applications & demonstrated uses

• Dynamic shaft and face sealing: rod, piston and face seals
• Energy sector: large-diameter face and static seals
• FPSO turret swivels and rotating interfaces
• Aviation: landing gearbox actuator shafts, auxiliary power units
• Cryogenic sealing examples: launch vehicle fuel tanks and related components

Customization & options

• Custom assemblies available with additional precision components to meet application requirements
• Silicone-filled spring cavity option for food processing and clean-in-place (CIP) environments
• Possible PFAS-Free* manufacturing depending on specification and application

Installation & resources
Installation guidance and an instructional video are available for small-diameter spring-energized seals. Product and technical handbooks cover seal design, selection and installation best practices.
