Elastomer or Plastic… Which Should You Choose?

Kalrez KLX-16011Gallagher Fluid Seals is a longtime partner of DuPont®’s, having specified thousands of DuPont perfluoroelastomer parts over the past few decades.

While elastomers were originally created as an alternative to natural rubber, they have expanded to include materials such as high-performance perfluoroelastomers for demanding applications.

These materials can also be used in place of plastics in most, if not all, applications. DuPont is at the forefront of perfluoroelastomer development, creating elastomers with properties that can help meet highly specific application requirements.

Read on to learn more from Dupont about the differences between elastomers and plastics, and how elastomeric seals perform compared to plastic seals.

New Video: PTFE Fillers Used During Manufacturing


 

In our latest video, Gallagher Fluid Seals Engineering Manager Craig Beil discusses the various PTFE fillers used in making seal materials. Fillers include carbon, glass, stainless steel and molybdenum disulfide. Watch the video to learn more about what PTFE fillers can do, and be sure to watch the other videos in our series.

Past videos have explored issues such as radial seal misalignment,  the use of spring energized seals and environmentally-designed static seal gaskets.

We hope you can find something useful in each one.

 

 

Garlock THERMa-PUR Style 4122

THERMa-PURTHERMa-PUR™ is a proprietary new gasketing material created by Garlock and designed for use in high temperature sealing applications. It is produced using an environmentally friendly, solvent-free process and combines a unique formulation with a patent-pending fiber core. THERMa-PUR is yet another innovative Garlock Sealing Technologies sealing solution that provides more than just temperature resistance.

Preliminary Considerations for Spring-Energized Seals

springsealsToday we’ll continue our look at spring-energized seals by exploring some of the preliminary considerations to made when working with these seals.

A spring energized PTFE seal is selected to fit an exact set of service conditions found in your application.

Gallagher Fluid Seals recommends conducting a review of the entire sealing environment. You should use the Engineering Action Request (EAR) form before selecting a seal design.

New Video: Radial Seal Misalignment Issues


 

Once again, Gallagher Fluid Seals is pleased to bring its readers another video. This time out, we’re dealing with radial seal misalignment issues.

In this clip, Gallagher Engineering Manager Craig Beil discusses shaft run out and shaft eccentricity, two common radial seal misalignment issues.

Be sure to watch our previous videos on GORE expanded PTFE seals, static seal gaskets and spring energized seals to learn more about our products.

And don’t hesitate to contact Gallagher with any questions, whether they’re about radial seal misalignment or any other product or service. We’ll be happy to help.

Freudenberg Energy Saving Seal

Energy Saving SealThanks to the combination of elastomers capable of withstanding extraordinarily high thermal loads and a friction-optimized sealing lip, the energy-saving seal (ESS) enables the power loss in drive assemblies to be greatly reduced.

The radial shaft seal ESS improves sealing performance by reducing friction between the seal lip and crankshaft through a reduction in radial load of 50% when compared to sprung rubber lip seals and 75% when compared to PTFE lip seals.

Not only does the friction improvement reduce power consumption and improve fuel economy, it also reduces the amount of heat generated at the seal lip and crankshaft interface. The reduction in heat reduces the potential for coked oil build-up and heat aging (hardening) of the rubber. Coked oil build-up, which can reduce the pumping capability and is a typical failure mode of standard PTFE seals, is virtually eliminated.

New Video: Spring Energized Seals


 

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, whether they’re about spring energized seals or any other product or service. We’ll be happy to hear from you.

Reduce Standard Groove Size with Parker Diamond Seals+

Parker Diamond SealsParker Diamond Seals are designed to be a compact, robust axial seal alternative to standard cross section seals. Their unique design allows for reduced compression forces, making them ideal for small, lightweight housings in aerospace and military applications.

Narrow cross section
With a tall and narrow diamond-like cross section, the diamond seal groove is 60% narrower than traditional grooves for comparable seal heights. The narrow cross section of the seal allows it to be used in tight corners and around small holes. The groove width savings allows housing to become thinner, reducing the weight assemblies and is less expensive to machine when compared to standard grooves.
