RACO® Spring-Energized Seals

RACO® polymer seals have a U-shaped spring design and are used in extreme face sealing conditions, including cryogenic fluids and high vacuum. This sealing solution features a high-performance polymer jacket energized by a corrosion resistant, heavy duty/high load RACO® spring that provides a very high spring force along the sealing lip.

These seals are deeply rooted in history, being created by a sealing pioneer to solve cryogenic issues in the first space missions. Watch the Omniseal® origin story or read about its history to see this seal's critical role.

 

Other typical precision applications include: Space seals for propulsion systems and Energy custom seals for LNG loading arm swivels.

Is this Component PFAS-Free*?

Depending on the application and equipment specifications, we may be able to manufacture this solution PFAS-Free*.

Contact our engineers to learn more and start the discussion on how we can support you to meet the requirements of your application.

* PFAS-Free here means we do not intentionally add PFAS material in the product, but does not exclude the possibility of traces, as these materials are common in the environment.

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..
