In rotating applications, proper surface finish is crucial for getting positive sealing and the longest seal life possible. Rotating surfaces that are too rough could create leak paths and can also be very abrasive. Unlike elastomer contact seals, PTFE lips can run on very smooth surfaces regardless of lubrication.

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.

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.

Pneumatic tools are common in factories, tool shops, and DIY garages around the world. Using compressed air for power is convenient, simple, and — when maintained properly — safe and efficient. However, air treatment costs can add up fast. Traditional rubber seals used in air tools require clean, low moisture, compressed air with the proper amount of lubrication added. Good Filter/Regulator/Lubricator systems (FRLs) cost as much as the tools themselves! So, what would happen if we didn’t have to provide pristine air?

Things like pressure, temperature, and systems dynamics can create challenges for many standard seals. Many food production processes involve cooking or pasteurizing so high temperature performance requirements are often called for. Production line operations can demand seals capable of handling high-speed dynamics and extreme duty cycles.

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.

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.

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

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″.

Today we have the technology to create seals for tools which don’t require daily or even yearly upkeep. You’ll find these tools labeled “maintenance-free,” which sounds great to the guy responsible for maintenance. It sounds

In many respects, troubleshooting and failure analysis of compression packing materials is similar to the investigation of a crime scene. A good investigator knows how to gather clues from many different sources and put them together to understand what has happened. A good troubleshooter uses the same information gathering method, familiarizing themselves with the sealing materials, the process equipment and the systems where they are used.

The Food and Beverage industry presents some unique challenges in the sealing world. FDA compliance and Clean-In-Place requirements can complicate seal design and potentially limit material selection. With these additional considerations, Food Industry seals often still must operate under the same strenuous conditions and performance specifics as many industrial or aerospace applications.
