There are a multitude of options when it comes to selecting the most suitable sealing product for your application. And for those who are not familiar with sealing technology, the number of options can be really confusing. Gallagher can help.
We pride ourselves on being “The Seal Specialist”, and our engineering department is ready to help seal your toughest application. But where do you even start? Keep reading to learn more about some of the fundamentals of seal design and fluid power sealing theory from our partners at Parker.

Seals are the most crucial element of a fluid power system, and the engineers at Gallagher have spent more than 60 years cultivating their fluid power sealing skills.
Fluid power seals need to be able to survive higher pressures and more extreme conditions, while having to seal against evolving fluids.

Gallagher Fluid Seals has long been a supplier of seals to the energy, oil and gas industry.
From sealing applications in the renewable energy sector (hydroelectric, solar, wind, and thermal) to more traditional fossil fuel exploration and extraction in extreme environments, we’ve pretty much seen it all.
One of the newer products energy/oil/gas sector products we've been working with is biodiesel. And Parker, one of our most trusted sealing partners, has compounds made specifically for biodiesel.

Today we’ll continue our look at spring energized seals by discussing gland designs and installation.
We begin with two-piece glands. Spring energized PTFE seals are rigid when compared to elastomer seals such as O-rings, and can be damaged if stretched or compressed beyond their material limitations.
That’s why we recommend using a two-piece, split gland design whenever possible. This allows easy installation or removal of the spring energized PTFE seal without the need for additional tools, and will greatly reduce the risk of damage to the seal.
Lead-in chamfers that are blended and very smooth are needed to prevent seal damage during installation. You can find full surface finish recommendations by downloading our complete spring-energized seal guide.

Gallagher Fluid Seals is happy to introduce its latest video, which deals with spring-energized seals.
In the clip above, Gallagher Engineering Manager Craig Beil discusses these seals and the tools and materials used to manufacture them. Gallagher can meet your requirements for PTFE sealing in most, if not all, environments and operating conditions.
Be sure to watch our previous videos on GORE expanded PTFE seals and static seal gaskets to learn more about our products.
And don't hesitate to contact Gallagher with any questions,

Founded in 1945, Minnesota Rubber and Plastics is a pioneer in the design and production of four-lobed seals with the Quad-Ring® Brand seal design.
Today these seals are used around the world for a wide variety of static and dynamic sealing applications.
Avoiding Spiral Twist
To minimize breakaway friction, an O-Ring groove must be wide enough to allow rolling or twisting of the seal. In the long stroke of a reciprocating seal application, this twisting action can strain and eventually tear the rubber, causing a failure mode known as spiral twist.
To prevent spiral twist, the Quad-Ring Brand seal four-lobed configuration is designed to withstand the distortion and extrusion often caused by high or pulsating pressure. To accommodate these forces, a Quad-Ring Brand seal uses a narrower groove than a comparable O-Ring seal.

Transmission development is a focus for emissions reduction. Dual-clutch transmissions or automatic transmissions with eight or more gears not only increase the efficiency of the drivetrain but also create new challenges.
Higher load generation is one major challenge of dual-clutch transmissions and seals from Freudenberg Sealing Technologies made from PEEK (polyetheretherketone) or PAI (polyamideimide), in conjunction with their low-torque design, are a dependable solution to high load pressure. And Gallagher is proud to be your Freudenberg Sealing Technologies distributor.
