Gore® GFO® Fiber vs Graphite/PTFE Packing
When tested alongside generic graphite/PTFE packing, packing made of 100% Gore® GFO® Fiber achieves better results for all key attributes: creep resistance, retention of lubricant, sealability, and stability (shrinkage).
The differences in performances for each generic packings will have an impact on the operational costs.

The ZAVA® Seal-Ring - Quick and Easy Installation
"At last" - that's the reaction of those who have been plagued by the constant need to change rubber seals on VFA and CCA filters at pulp plants all over the world. As an electrician at SCA Pulp in Sundsvall, Frans Sramek is the man that has solved this well-known, and seemingly hopeless problem. The ZAVA seal can be mounted in minute and cuts maintenance costs substantially.
"It’s always a pleasure to be able to offer our customers products on which they make money,” says Lars Bylund, Customer Service Division at Sunds Defibrator.

In the process industry, the Simmerring® Radiamatic HTS II shaft seal ring offers diverse options for its use, such as bottling systems, food equipment, and pharmaceutical and cosmetics units, along with mixers. The key advantage of HTS II shaft seal rings is their high resistance to media since the substances only come into contact with PTFE. This makes it possible to achieve particularly hygienic processes. For approaches based on hygienic design, Freudenberg Sealing Technologies offers dead-space-free variations, such as HTS II 9539 VL with a forward-positioned seal lip.

Gore is working with membrane electrode assemblies in fuel cells to help decarbonize applications from drones to warehouses.
While fuel cells have been around for almost a century, over the past decade their development has rapidly increased because of their potential to produce sustainable energy.
Fuel cells are designed to convert the chemical energy of hydrogen and oxygen into electrical energy. The cell itself consists of an anode and cathode, sandwiched around an electrolyte—a liquid or gel containing ions (also contained in batteries).
W. L. Gore & Associates, a global materials science company with its U.S. headquarters based in Newark, Delaware, produces items derived from fluoropolymers. Gore is also one of the leading suppliers of membrane electrode assemblies (MEAs), the core component that helps to initiate the electrochemical reaction required to separate electrons in fuel cells.
The MEAs produced by Gore is currently

Sealants are necessary in a variety of different facets of life to ensure the preservation of certain products or machinery. This is because sealant are substances that essentially block the passage of fluids or air through the surface, joints, or opening in certain materials, machinery, or piping. There are a wide variety of sealants depending on your needs. If you have heard of hermetic sealing and wondered, what is hermetic sealing, you are in the right place. Below you will find more information on what hermetic sealing is, it’s historical evolution, and what it is used for.
What is Hermetic Sealing?
Hermetic sealing is essentially a watertight and airtight sealant.

Stick-slip is a common phenomenon that can occur in seals due to uneven friction between objects sliding across each other.
This repetitive start-stop movement or vibration known as stick-slip can cause major issues and even failure of mechanical systems, including seals. However, proper seal design and knowing what to look for can help you avoid stick-slip in your machinery’s seals.
Here’s why stick-slip happens and how you can prevent this problem in your seals.
Stick-Slip in Everyday Life
Stick-slip is familiar experience for most of us

A common question that comes from many customers is: “Can you tell me which O-ring compound meets this ASTM D2000 callout?” It’s understandable, since at first glance, the ASTM D2000 callout can be intimidating for determining the type of O-ring material. However, the ASTM D2000 is a very useful tool to quickly specify requirements for O-ring materials, and is standardized so it is easy to interpret industry wide. So, what is the ASTM D2000 specification, and how can I interpret it?
What is ASTM D2000?
ASTM D2000 is a standardized description of rubber compounds. It was first developed for use in the automotive industry, however it is now used by many industries to specify requirements for rubber compounds in a consistent way. Think of the specification as a common language everyone in the rubber industry speaks, allowing us to communicate easily with each other without an interpreter. An ASTM D2000 callout
