Sheet materials are sold in a wide variety of material types and thicknesses, with the best choice for any given application being entirely dependent on the nature of the task the gasket will be performing. In this blog post, we’ll look at some of the different types of gasket sheet types and provide a high level overview of the best applicable uses.
All materials offered for fabricated gaskets can be purchased as whole or partial sheets from Gallagher Fluid Seals. All gasket sheet materials are in stock, and can be shipped within 24 hours.

The machining of polymers such as PTFE, still remains somewhat of a specialty operation. While there are a plethora of machine shops dotted across the country focused on metal turning and milling operations, few specialize in plastics.
Only someone experienced in metalworking might call machining something like PTFE easy. PTFE is much softer and easier to cut than something like steel or aluminum.
While this certainly is true, polymers present their own unique set of manufacturing challenges, especially when tight-tolerance parts are required. And with Eclipse’s business of aerospace and specialty applications, they almost always are.

Fastener Seals consist of an inner rubber component used in conjunction with an outer metal washer that supports the sealing function of a fastener such as a screw or bolt. The rubber and metal combination create an ideal fit to eliminate any clearance gaps between the housing components and protects against potential leaks in many static applications.
Fastener seals are intended to take the place of an o-ring in certain assemblies. By using a fastener seal, there is no need to have an o-ring groove machined into the component that the fastener will pass through.
GFS offers 3 different Fastener Seal Profiles for purchase below. Standard sizes and materials are kept in stock for same day shipment.

Due to the growing energy density of battery systems, the developers of lithium ion batteries must satisfy ever higher safety requirements. It is especially crucial to keep a single damaged cell from overheating the entire battery module. Freudenberg Sealing Technologies has developed an innovative heat shield for use in prismatic and pouch cells with almost no impact on the required installation space. It combines the high heat resistance of a silicone-based elastomer with the high insulating properties of air.
The goal is greater range without the battery growing in size and weight: High energy density, which has been battery developers’ top priority, creates a basis for the broad acceptance of electric vehicles. But the more energy is stored in a confined space, the greater the safety requirements. So precautions are essential in case a damaged cell overheats. Experts call the phenomenon

Cartex® Cartridge Mechanical Seal
EagleBurgmann's Cartex mechanical seal is fully pre-assembled is designed with greater attention to functional details like tighter tolerances for more accurate seal operation, greater axial movement to handle pump shaft movement, seal parts with robust cross sections for optimal seal stability in operation, and castings that meet ASTM A 351/351M standards for proven quality. The seals are installed in pumps in a wide range of industries including chemicals, water supply, paper production, food processing and many other applications. Cartridge seals are easy to fit, and they keep your running costs down.
The Cartex® cartridge seal line now includes single and double seal versions for all standard operating modes as well as special versions. For example: the Cartex range is now applicable for sterile applications or installation in positive displacement pumps.

As the operating parameters of industrial technologies and manufacturing processes get more extreme, the need for optimal sealing solutions become that much more important.
Elevated temperatures and pressures, higher speeds, extreme environments, faster gas decompression, and aggressive medias all make sealing more critical. This extends right across static, reciprocating, rotary, and oscillating applications.
This challenge has been met very effectively by the inventive addition of energizers to seals. Energized seals give the ultimate performance in the most demanding conditions and critical applications.
Spring or o-ring energizers can extend the normal limits of PTFE and plastic materials to deliver durable ultra-tight sealing capability. Here’s a rundown of how energizers work and how they can elevate your next sealing challenge.

A 54%-per-component saving has been realised by Powerworks following the replacement of bronze bushings with a Vesconite low-friction bearings in the Jetstream turbine starters.
This is according to Powerworks Manufacturing Manager who was responsible for the initiative to replace the bushing located inside a drive spindle that acts as a guide for the spindle.
Testing for normal operation
The Manufacturing Manager noted that the saving has been achieved without any loss in performance, as attested to by six months of in-house testing on a Detroit 6-cylinder engine, a dynamometer, as well as on hydraulic test benches to test the efficiency of the motor.
Powerworks confirmed that the specific bushing was not subject to rotational wear in normal operation as it only moves backwards and forwards.
Vesconite was tested for this motion and no appreciable wear was measured, says a company representative.
