Types of Springs in Spring Energized Seals
Are you looking for spring energized face seals?
GFS Spring Energized Face Seals are designed for applications with high pressures and temperatures, cryogenic fluids, extreme media and other service conditions which exceed the performance characteristics of O-rings and conventional elastomeric seals.

PTFE Radial Lip Seal Design
Before selecting a seal type and the filled PTFE compound to be used in a proposal, it’s important to have a thorough understanding of operating conditions and how they affect the seal performance.

PTFE (Polytetrafluoroethylene) is a synthetic fluoropolymer of tetrafluoroethylene. It is a solid form of fluorocarbon and a compound with elevated molecular weight. It consists entirely of fluorine and carbon atoms. It is hydrophobic, which means that it cannot be made wet by substances containing water or by water itself. This is possible due to fluorine’s high electro-negativity and low levels of friction coefficients against all types of solids.
Common reasons to upgrade to PTFE sealing solution:
- Suitable for many industries, including: Heavy Equipment, Aerospace, Environmental (solar, wind, electric batteries, Automotive, Lab/Scientific, and Aerospace
- High temperature rating
- Higher pressure rating than standard rubbers
- Friction coefficient extremely low (Low coefficient of friction)
- Ability to handle aggressive media(Aggressive

components their machines need in order to operate and produce their desired end product. The ways that tooling impacts a manufacturing operation are imperative. Not only is the tooling of your own manufacturing important, but also of the tools themselves that will be a part of your own operation. It’s necessary to have components that have been tooled to specifications, have high quality, and will perform under stress.
Potential Effects of Tooling
The end result of your operation’s tooling is going to affect every aspect of the business and its success. If an operation has been improperly tooled, then it will inevitably have a less efficient running cost, slowing things down. When an improperly tooled machine fails, it can have disastrous consequences, not limited to time lost, loss of product, and potential hazard to employees or customers.

Custom Seals from Gallagher Fluid Seals
While you could buy seals made with the size and materials of industry standards, sometimes the performance may not be up-to-snuff. Whether you have a static or a dynamic application, each one has its own unique traits and characteristics. Rather than finding a product that "fills the needs" of your specific application, wouldn't it be more prudent to create the perfect solution?
Using custom-engineered seals from GFS, specific to your application, can help solve that.
Size
No matter the size, Gallagher can assist. Whether less than 1 millimeter or dozens of inches of diameter, our expert engineering team can help design the solution for the exact dimensions you need. Our ability to have the exact sizes and designs fabricated with our global partnerships can help you get it for the right price, too.

This new case study from Gallagher Fluid Seals outlines the benefits of using a PTFE spring energized seal in high friction applications.
Our customer is a manufacturer of power transmission products with a focus on magnetic force. Their product line includes magnetic capping heads, shaft couplings, current-controlled brakes, and clutches.
CUSTOMER PROBLEM:
The customer's magnetic clutch and was having design problems with high friction and break-away force, ultimately causing delayed production schedules.

The machining of polymers such as PTFE, still remains somewhat of a specialty operation. While there are a plethora of machine shops dotted across the country focused on metal turning and milling operations, few specialize in plastics.
Only someone experienced in metalworking might call machining something like PTFE easy. PTFE is much softer and easier to cut than something like steel or aluminum.
While this certainly is true, polymers present their own unique set of manufacturing challenges, especially when tight-tolerance parts are required. And with Eclipse’s business of aerospace and specialty applications, they almost always are.

As the operating parameters of industrial technologies and manufacturing processes get more extreme, the need for optimal sealing solutions become that much more important.
Elevated temperatures and pressures, higher speeds, extreme environments, faster gas decompression, and aggressive medias all make sealing more critical. This extends right across static, reciprocating, rotary, and oscillating applications.
This challenge has been met very effectively by the inventive addition of energizers to seals. Energized seals give the ultimate performance in the most demanding conditions and critical applications.
Spring or o-ring energizers can extend the normal limits of PTFE and plastic materials to deliver durable ultra-tight sealing capability. Here’s a rundown of how energizers work and how they can elevate your next sealing challenge.

Polytetrafluoroethylene (PTFE) resin is a highly effective material for seal consumers due to its extremely low friction, high heat tolerance and chemical inertness.
With the right additives, PTFE resin can perform even better in terms of strength, thermal performance, chemical resistance and abrasion.
However, there are a few design considerations when using PTFE resin, particularly when combined with glass fiber and bronze.
This blog will examine PTFE fillers to enhance PTFE performance.

Below, we’ll explore how Teflon is processed for sealing purposes, and why we sometimes see variation in surface quality and/or cracks in finished Teflon seals.
The Two Ways to Process Teflon® for Seals
There are different grades of Fluoropolymers that can be used to manufacture seals. There are melt processable fluoropolymers, which are rarely used in the seal manufacturing process due to cost, and granular PTFE.
Melt processable fluoropolymers allow for injection molding, and exhibit many of the same characteristics as granular PTFE. But the first grade
