USA – An aeration windmill manufacturer installed Vesconite Hilube bushings on its windmills, leading to smoother and more efficient operation. The bushings are an essential component in aeration windmills, which aerate ponds in private and public spaces, since fan rotation is key to ensuring that the diaphragm moves up; compressed air is taken in; and the compressor builds up pressure, which is released into the air line leading to the water. Because of this, the windmills are more efficient at reducing algae and foul smells, controlling mosquitos and creating a healthier environment for fish.
Vesconite for Renewable Energy
Vesconite Hilube bushings reduce energy costs in renewable energy applications. Turbines associated with these applications need to move rapidly and easily to produce efficient power, meaning wind, wave, tidal and current-driven turbines require a low coefficient of friction. Reduced energy losses as a result of the lower friction present in Vesconite Hilube bushings, allow turbines to rotate easily, producing electricity faster and at a reduced cost.

GYLON EPIX™ is a family of gaskets that effectively seals a broader range of applications and is more forgiving during the installation process. It allows the end user to save valuable turn-around time, reduce re-work, and lower costs, helping them to finish ahead of schedule and under budget.
GYLON EPIX™ features a hexagonal surface profile that provides the torque retention and blowout resistance of a thin gasket and the conformability of a thicker gasket. GYLON EPIX™ Style 3504 EPX is a high performance, aluminosilicate microsphere filled PTFE sheet material designed for use in moderate concentrations of acids, and caustics, as well as hydrocarbons, refrigerants, and more.
Customer reported problems with continuous leaks that required ongoing maintenance and attention taking manpower and resources away from other critical operations for the plant.

O-Ring Selection Made Easy with the Parker O-Ring Selector
Two things are equally important for the reliable performance of an O-Ring seal: the right size and the right material. Parker’s new O-Ring Selector is an engineering tool that enables users to make the right material and size selections easily, quickly and reliably – in a single application. The accuracy of the results ensures the desired performance of the O-Ring in the subsequent application. This is primarily based on the fact that both functionalities – the material selection and the O-Ring size calculation – are closely interlinked. This achieves a new quality in calculating the total sealing system.
Overview of the O-Ring Selector
The Parker O-Ring Selector is divided into three main sections:
- Service Conditions & Material Selector
- Size Selector
The Service Conditions & Material Selector section is focused on mapping the material-related application conditions. Entering the operating temperature range, the desired polymer family and/or material hardness will take the user to the suitable material selection. The Advanced Material Selector enables experienced users to specify the operating conditions in even greater detail. Here the medium to be sealed can be selected from a database containing 2,500 media. In addition, a search for required approvals and conformities can be run.

Gallagher recently published its Failure Modes of Elastomers in the Semiconductor Industry White Paper, now available for download on our site. This white paper discusses common issues that occur with elastomer seals in the semiconductor industry. The excerpt below is the fourth and final section of our new white paper, discussing Volatiles (offgassing) and Particle Generation. To download the white paper in its entirety, visit our Resources Page, or click on the image to the right.
Failure Modes of Elastomers in the Semiconductor Industry
High performance elastomers are found in many applications in the semiconductor industry (see paper titled Perfluoroelastomers in the Semiconductor Industry). Though perfluoroelastomer (FFKM) seals are formulated to meet the highest performance requirements of integrated circuit (chip) manufacturers, even these elastomers can’t solve every sealing application nor will they last forever in service. Additionally, end users need to understand subtle performance differences between perfluoroelastomers in the same product line. For example, one product may be better at minimizing particle generation while another may be better for high temperature services.

Orion’s Path to Innovative Bearing Protection Technology and the Issuing of their Patent
Since the opening of Orion Engineered Seals in 2011, their team has been working tirelessly to ensure they have the most innovative products available to increase the reliability of rotating equipment. Among their various product lines, it is their patented Bearing Protection Device (BPD) in its many design variations that separates them from their competition. In March of 2017, after a long yet rewarding process, they were issued a US PATENT for their robust and distinctly innovative Bearing Protection Device (BPD) technology. There is so much they could say about why their products stand above their competition, but today we’re going to focus specifically on the team behind the BPD and why Orion has been so successful.
Todd Brickson, Director of Engineering has been working in manufacturing for over 25 years and is enjoying the fruits of his hard work. When designing the BPD device he had a few key points going through his mind.
- To create the most effective, innovative, and efficient design in bearing protection
- How can we be innovative in the market and create something that has never been seen before
- Develop multiple internal layers of contaminant control that would surpass any design available in the market today.

What is an Elastomer?
An elastomer is made up of long chain polymers which are connected by crosslinks. Crosslinks are analogous to springs and provide an “elastic” (recovery) nature to the material. The crosslinks are relatively stable, but can break down under extreme temperatures and pressures.

Brazil, Paraguay and Argentina – The waters of the Parana River tend to be wide and deep, with significant suspended debris and sand. Due to these abrasive conditions, rudder bearings on tug boats operating on the river are susceptible to rapid wear. The result is frequent dry docking for repairs. In response, Vesconite bushings have been successfully fitted to 20 tug boats working the Parana River. The combination of exceptionally low wear, self-lubrication and easy installation makes it an ideal material for this application.
Vesconite for Marine Applications
Vesconite, and Vesconite Hilube in particular, are ideal for the submerged and corrosive conditions of the marine industry. Suited to both dry and underwater applications, Vesconite’s internal lubricants allow for prolonged life where the setting is characterized by irregular greasing schedules, or no greasing at all. Unlike most bearing materials, Vesconite offers long wear life and a high load-bearing capacity with no distortion or delamination, despite the wet and abrasive working environment. Vesconite is easily removed and refitted, saving in costly downtime.

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.
Watch the video below to learn more about GYLON EPIX™, and how it’s patented
hexagonal surface profile can help you reduce gasket installation issues.
GYLON EPIX™ will provide superior functional performance by combining the traditional attributes of GYLON® with an innovative surface design. It offers a broader range of applications than traditional PTFE gaskets that are used in worn and pitted flanges. In addition, this evolutionary material delivers the tight sealing and load retention properties of 1/16” (1.6mm) and the conformability of 1/8” (3.2mm). The hexagonal profile provides improved compressibility and recovery. The profiled surface reduces the contact area during initial compression to concentrate the compressive force of the flange for improved sealability.
Designed for increased compressibility, GYLON EPIX™ improves performance in misaligned flanges. The consolidation of two thicknesses to one reduces the need to inventory multiple thicknesses. Garlock is dedicated to providing real sealing solutions that meet real world sealing needs. With an improved design, color-coded materials, and single thickness, GYLON EPIX™ makes sealing easier.
