Expanded polytetrafluoroethylene, or ePTFE, is the core material in many of Gore’s solutions. An ePTFE membrane is created when PTFE — a linear polymer consisting of fluorine and carbon molecules — is expanded, creating a microporous structure with very desirable characteristics, including a high strength-to-weight ratio, biocompatibility, high thermal resistance and many others.
Gallagher Fluid Seals is pleased to introduce its newest video, which discusses GORE expanded PTFE.
The clip features our engineering manager Craig Beil discussing
CNC machining, which stands for Computer Numerical Control, is a manufacturing process in which pre-programmed computer software dictates the movement of tools and machinery.
The process can be used to control a range of complex machinery, from grinders and lathes to mills and CNC routers.
But in our case, Gallagher is utilizing this process to cut both custom and standard seal profiles for our customers.

Heavy duty equipment moves industry forward in all climates, from the sunny Caribbean to icy Greenland. Effective, reliable sealing is what allows hydraulic systems in heavy duty equipment to do work, no matter the temperature. Reliable sealing solutions allow cylinders on dump trucks
Die cutting is an all-inclusive term for the process of using a die to cut sheets or rolls of a variety of materials, such as foils, laminates, gasket materials, polyesters, polycarbonates, and more.
Recently, a customer was having difficulty with a seal failure on a fluid power application. The high-pressure, high-eccentricity seal operates in conditions up to 200,000 pv at 3000 psi and could not exceed maximum shaft deflection of 0.005″.
Vanseal works with these types of seal applications frequently and used a Unitized Seal that uses several components to address each of the various sealing challenges.
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.
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.
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.
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.
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.
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.
