PEEK Spring Energized Seal in a High Temperature and High Radiation Application
One distinct environment presents a particularly challenging set of circumstances for seal design – high radiation. Gallagher Fluid Seals partners with Eclipse Engineering on many unique customer projects. Eclipse’s primary seal material choice for many applications is PTFE and PTFE blends. With all the wonderful attributes PTFE possesses as a seal material, radiation resistance is not one. In high radiation environments

Types of Spring Energized Seal Lips
Spring Energized Seals can be found in all kinds of applications across the spectrum of industries and sectors. While the pros and cons of the different spring types contained in the seal are often discussed, the style of sealing lips can also have a significant impact on performance.
Every spring type has at least 4 standard lip style options, so choosing the right style for your application is critical. There are a number of design factors that need

PTFE Spring Energized Seal Provides Low Friction Performance in Food Product Dispenser
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.

V-Packing / Chevron Packing
V-Packings, also called V-Stacks or chevron packings, have been around for decades, and represent one of the earliest advanced sealing designs. While existing long before PTFE spring-energized seals came into being, they are still used in a variety of industries today.
Our partners at Eclipse Engineering design and manufacture their fair share of custom V-packings out of various materials every year. V-Packings offer a simple yet effective design principle.

Seals are small components that have a big function. At their most essential purpose, they keep fluid in and debris out. Failure to do this can lead to costly machine destruction, and even endanger the lives of people working around these machines. Preventing seal failure is very important on many different levels.
What Seals Are Up Against
Many factors can cause a seal failure. Being aware of these factors will help you in preventing an avoidable failure. Seals are under constant pressure

Contamination With Seals
Neglecting routine maintenance can cost you in seal performance or, in some cases, end with catastrophic failure. Prolonged downtime will incur losses that exceed the temporary cost of preventative maintenance.
It’s important to identify seal contaminants and their sources before they turn into larger issues. Here are some tips on what to look for and how to deal with them.
Common contaminants
Here are some typical contaminants you’ll come across:

Being commodity items, U-Cups are readily available in a number of materials and can be found on the shelf from multiple distributors and manufacturers in many standard sizes.
Named for the shape of their cross-section, a U-Cup’s design will be pressure energized increasing sealing effectiveness when compared to a standard O-Ring.
This means as

The oil and gas industry poses some of the most challenging seal applications for any seal designer. This is largely due to the varying chemical compatibility of fluids, and extremely high temperatures. The fluids often contain solids, which tend to be extremely abrasive. And applications are usually at high rotary speeds with extreme pressures.
This combination creates PV values (pressure x velocity) often reaching the limits of the seal materials. On top of these extremes, as seal designers
