Characteristics and performance

This widely used spring-energized seal offers performance benefits ranging from enhanced media compatibility to superior performance in broad temperature ranges.

The basic design consists of a U-shaped jacket made from inert thermoplastic materials specifically selected for the application. The addition of a metal spring actuates the jacket material used in the system, which provides sealing at low system pressures. At higher system pressures, the seal becomes pressure-energized by the fluid media—a sealing combination that ensures adequate sealing throughout the entire pressure range.

By coupling the OptiSeal® system with other specialty components such as anti-extrusion devices, PakRings, V-Rings, adapters, bushings, and bearings, users can achieve an expanded operational envelope.

Product details

With diameters from 0.040in (1mm) to 110in (2.8m), customisable heights and special geometries, the OptiSeal® system can be configured to fit in almost any hardware, making it the ideal choice for critical-service sealing.
