Omniseal® Spring-Energized Seals

OmniSeal-400-SES-Seal
Omniseal®
400 Spring-Energized Seals

This polymer seal has a cantilever spring design and is used in dynamic applications, providing good friction and leakage control at moderate pressures and temperatures. The sealing solution features a PTFE jacket energized by a corrosion resistant, v-shaped spring (jacket designed with a flange on the ends).

You can build a custom seal with additional parts to enhance performance. For example, silicone-filled spring cavities are available for food processing and clean-in-place applications. Typical precision components that have been proven successful include: Energy face and static seals with large diameter, welded back-up spring in FPSO turret swivels and aviation seals in landing gearbox actuator shafts and auxiliary power units (APUs).

Seal Function & Motion

Dynamic-Static-Seal-Function

Static & Dynamic Applications

There are two basic types of sealing applications: static and dynamic, in which at least two hardware surfaces come in contact with one another.

 

In static applications, there is essentially no relative motion between the hardware surfaces. A typical example may be flanges that are bolted together. Omniseal® Solutions offers mostly face seals in such applications.

 

In dynamic applications, at least one surface is in motion relative to the other. A typical example is a hydraulic cylinder with shaft and bore. Further, there are two directions of motion in dynamic applications: reciprocating or linear motion, and rotary (including oscillating) motion. We offer mostly radial seals (rod seals and piston seals) in such applications. Occasionally, the application may be a combination of both static and dynamic. For these more complex cases, you can contact our team of experts.

Face-Radial-Seal

Radial & Face Sealing

Based on the hardware configuration and location of seal glands, sealing can be either radial or axial (face sealing). Radial sealing has glands that compress seals in a radial direction. Male glands are machined in the shaft, whereas female glands are machined in the bore. Radial sealing is usually, but not always, dynamic.

 

We also offer rod seals and piston seals for these applications. Axial sealing has glands that compress seals parallel to the axis of the seal. Glands are machined on the face of the hardware. Axial sealing is usually, but not always, static. Omniseal® Solutions offers inside and outside face seals in such applications..
