From the outside, an elastomeric expansion joint looks to simply be made out of molded rubber. Part of the reason expansion joints are used in such a wide variety of applications is that the interior construction of a joint can be custom-designed to handle your specific application - materials of construction will depend on size, temperature, application, media, pressure (S.T.A.M.P.).
Layers of Construction
Tube
Synthetic or natural rubber forms seamless, leak-proof lining
Extends fully through bore to outer flange edge
Common materials include chlorobutyl, neoprene, natural rubber, EPDM, Viton* and Hypalon*
As we mentioned in our messaging earlier this year, DuPont was in the final stages of opening a new Kalrez® perfluoroelastomer parts manufacturing facility at their Tralee Park Annex site in Newark, Delaware.
We are happy to announce that the new facility is completed and running at full capacity.
Abrasive media comes in many forms—from mining slurries to wood pulp and even substances as seemingly mild as liquid chocolate. This diversity rules out a one-size-fits-all solution for abrasive pumping applications. However, today’s broad range of materials, from carbon fiber packing to graphite-filled polytetrafluoroethylene (PTFE) bushings, includes products capable of meeting an equally broad range of abrasive wear requirements.
Carbon Fiber Packing
Few materials offer the abrasive resistance and heat dissipation of carbon fiber yarns. Braided compression packing made from this material excels under extreme conditions, including exposure to a variety of chemicals, temperatures approaching 850 F (454 C) in oxygen-rich atmospheres (up to 1,200 F/649 C in steam) and shaft speeds in excess of 4,000 feet per minute (fpm).
East Longmeadow, MA | October 25, 2023 – Gallagher Fluid Seals is expanding! We are pleased to announce the grand opening of our new state-of-the-art warehouse in East Longmeadow, MA.
This new 15,000 square foot warehouse located at 142 Denslow Road is a climate controlled, energy efficient space which will store gaskets, O-rings, sheet material, braided packing, and a variety of other fluid seals for key customers.
With the new warehouse, Gallagher is expecting 26% staff growth in both its adjacent fabrication facility (136 Denslow Rd) and 142 Denslow.
O-rings are a critical component of equipment, machinery, and a variety of other applications. Shaped like a donut, the O-Ring can plays a significant role in industries across the globe. Most often, they are made from elastomers. They are designed to prevent fluid and gas from leaking around mating surfaces. Leakage on mating surfaces can cause serious damage and disrupt machining processes. That's why O-Rings are vitally important as they can effectively prevent this from happening. O-Rings can be made using a variety of different manufacturing processes, as you can see below.
Four Common Ways O-Rings are Manufactured
O-rings are an integral part of many applications as they are vital in maintaining the function and purpose of them.
Compression Molding (Transfer Molding): Compression molding is a highly efficient and cost effective technique.
Flange gasket storage is often an after-thought for many of our customers. While incorrect gasket installation procedures is the #1 culprit when it comes to gasket failure, gasket storage can play a large role in the quality of the gasket being installed.
Get the Most Out of Your Flange Gaskets
Gasket Performance Depends on Many Factors
Flange gaskets are highly engineered products, and their performance depends on many factors. Certainly design, manufacture, installation, and process conditions are all critical, but so is storage before use. Gasket materials often remain in storage for a long time before they are placed into service. Unfortunately, storage practices for gasket materials are generally not optimal or controlled well enough. This article provides guidance for the storage of different gasket materials to preserve their integrity.
Mica sheet is engineered for demanding operating conditions
KLINGER Milam PSS is an asbestos-free sealing material with a perforated stainless steel reinforcement. This high temperature, mica-based material is specifically designed to master the rigors of high-temperature sealing applications. It is the preferred choice for utilization scenarios such as exhaust pipes, turbines, turbochargers and fuel lines and can withstand temperatures of up to 1652°F (900°C) and pressures up to 72 psi (5 bar).
Because of its excellent chemical resistance to solvents, aggressive acids, alkalis and mineral oils, gaskets from this material can be used in a variety of industries.
This product is also available as Milam H, a high-quality homogeneous mica sheet.
Gallagher Fluid Seals is a Parker Distributor is proud to be proud to be one of the few premier distributors to qualify as a “Parker Seal Technology Center (STC)”.
Do you have an application where traceability and security is crucial for your sealing needs?
RFID for O-Rings
O-ring RFID (Radio Frequency Identification) is a technology that continues to improve by leaps and bounds. O-ring Identification is necessary in industries and applications where authenticity, traceability, and security are crucial.
Parker Hannifin, the global leader in motion and control technologies has created the Parker Tracking System (PTS). It
Vesconite’s ability to withstand various chemicals has been proven in an ultrasonic cleaning application, where bushings made from the chemically-resistant material were fitted to an ultrasonic cleaning machine designed to handle 170,000 parts per day.
The bushings were fitted to the transport cages on the conveyor.
They were immersed in the cleaning liquid, which acted as the only lubrication, and were in contact with the swarf from the cleaning process.
Ultrasonic cleaners are typically used to clean complex parts
