Transportation / Automotive bushings require regular maintenance and greasing, and are prone to wear especially in wet or dirty conditions. Self-lubricating Vesconite and Vesconite Hilube eliminate the need for continual greasing and at the same time increases bushing life. Vesconite and Vesconite Hilube are tough and durable and perform well under the mechanical stress that occurs on vehicle suspension systems.
Rail container trailers fitted with Vesconite
South Africa – Vesconite flanged pivot bushings have been successfully installed and used on container trailers at the national rail utility. The Vesconite bushes, with a flange of 205 mm diameter and a bore of 165 mm, were fitted to the walking beam center pivot bearing that equalizes component parts of the rear axle bogies. This heavy duty application required a material which had high load carrying capacity, low friction, high wear resistance and good dimensional stability. Vesconite, with all these characteristics, was used on the trailers that are used to transport 12-m-long general purpose containers.

One of the greatest challenges of the 21st century is the conversion to a resource-conserving, sustainable economy. With this in mind, Freudenberg Sealing Technologies is offering customers its FluoroXprene® family of materials to help contribute to this transformation. Originally developed for use in fuel lines, these materials have the potential for use in new, challenging applications thanks to their outstanding characteristics.
FluoroXprene was developed to reduce the permeation of fuel vapors through the walls of fuel lines. This permeation makes a notable contribution to a vehicle’s hazardous emissions. But it is often overlooked when considering total emissions. FluoroXprene reduces the escape of fuel vapors through the walls of fuel hoses into the atmosphere, slashing them to a fraction of their usual amounts. And this is not just the case for standard fuels – alternative plant-based fuels such as E10 and E85 are also securely contained by FluoroXprene materials.

Gallagher Fluid Seals recently made our Process Seals Webinar available on the website.
Food & Beverage, Pharmaceutical, and Chemical Processing industries have different requirements than typical seals. Process seals need to have multiple media resistance.
Unlike a traditional seal that only needs to be concerned with the media running through it, process seals also have to be designed to withstand the cleaning media being used.
This webinar will discuss:
- Material specification and development
- The importance of hygienic design
- Material compatibility and flavor transfer
We will be posting portions of the webinar on our blog, so keep an eye out! To download the webinar in its entirety, simply visit our Resources page, or click on the image at the beginning of the article.
This webinar was produced in conjunction with Dichtomatik Americas, a Freudenberg Brand. With a broad array of products and materials, but more importantly comprehensive knowledge and technical expertise, Dichtomatik has earned its title as market leader for sealing solutions in food & beverage, pharmaceutical, and chemical processing industries.
Poppet Seals for Demand Flow Regulators
Avoid Leakage and Support a More Accurate System
There are many applications in industrial settings where fluid must be sealed and released in calibrated quantities. Some examples include pressure regulators, relief values, fuel nozzles, or gas metering. Specifically a demand flow regulator is designed for use with various industrial instruments and uses a pump to draw the calibration of gas. It is crucial that there is no leakage of the fluid for the system to operate properly.
Parker Composite Sealing Systems Division designs different poppets to help control leakage in flow control applications. Our poppet is used to help keep the demand flow regulators in the “closed” position. And when the user “demands” gas flow, a diaphragm pushes down on the seat stem of the Poppet to help monitor the flow of gas.

GYLON EPIX™ is a newly developed family of PTFE gaskets. It is manufactured using a patented, profiled surface based on our proven Fawn, Off-White, and Blue GYLON® to create highly conformable materials for optimum sealing performance.
THE EPIX™ DIFFERENCE
GYLON EPIX™ and a traditional full face gasket were installed in a 3”-150# flat face flange at 120 ft.lbs. with pressure sensitive film. The film revealed that the traditional material saw heavier loading-near and around the bolts, and lighter loading at the points furthest from the bolts. The GYLON EPIX™ was able to distribute the load more evenly and prevent the low loading phenomenon.
The pressure sensitive film was then analyzed with special software that translate the various shades of red into a full color spectrum that provides a better visualization of the stresses that were developed on each of the gaskets. Again, while the traditional gasket saw areas of lower stress (green and blue areas), the hexagonal pattern in the GYLON EPIX™ concentrated and distributed the stress more evenly across the entire gasket.

We receive many requests from customers asking for recommendations on how to retain seals in an application. One of the most popular “quick fixes” is to apply liberal amounts of adhesive to a standard O-ring type product without respect to groove shape or sealing function. However, Parker OES provides a wide array of sealing technologies, offering innovative solutions to accommodate the challenging and vast sealing needs of our customers.
Replacing RTV with Pre-Applied PSA
A customer had been using a standard O-ring product on an outdoor electronic device. This part was sealing the external edge of the enclosure and meant to keep out water and dust. The enclosure was plastic injection molded so this extreme edge had irregular geometry to accommodate the molding process. The original proposal was to shove O-ring cord in place and adhere it down with RTV (Room Temperature Vulcanization) so that it did not fall out during assembly. This left a rust colored stripe exposed on a consumer device due to fitment issues. Parker’s proposal was to replace the O-ring cord with a custom hollow extrusion that fit the available space and allowed complete closure, thus not exposing the seal to be visible. The RTV process was replaced with PSA (Pressure Sensitive Adhesive) that was preassembled to the seal and allowed for quick and clean placement during assembly and retention for any maintenance needed.
