Customers often call with various sealing challenges. But sometimes their dilemmas can be solved with more robust solutions instead of direct replacements. For example, when a customer is having issues with a PSA-backed hollow seal that keeps peeling away from the bottom surface.

Incorrect O-ring installation can lead to assembly damage causing leakage during the first pressure test. If the system does not pressurize properly, the entire piece of equipment should be disassembled and seals must be replaced. Depending on when this test occurs, multiple manufacturing steps could be in between the seal installation and the first step where leakage can be identified. If O-ring damage happens with high frequency, you could be wasting time and money
A common question that comes from many customers is: “Can you tell me which O-ring compound meets this ASTM D2000 callout?” It’s understandable, since at first glance, the ASTM D2000 callout can be intimidating for determining the type of O-ring material. However, the ASTM D2000 is a very useful tool to quickly specify requirements for O-ring materials, and is standardized so it is easy to interpret industry wide. So, what is the ASTM D2000 specification, and how can I interpret it?
ASTM D2000 is a standardized description of rubber compounds. It was first developed for use in the automotive industry, however it is now used by many industries to specify requirements for rubber compounds in a consistent way. Think of the specification as a common language everyone in the rubber industry speaks, allowing us to communicate easily with each other without an interpreter. An ASTM D2000 callout

Sealing decisions are often left until the end of product development. By the time an email is sent to Gallagher Fluid Seals, the gland may already be fixed. This may not pose a problem in many applications, but it can often leave the seal engineer with few options. Having input from the seal expert in the early stages will allow for greater flexibility in choosing a seal and better chances at optimal sealing.
Thermo-Chem™ firewall sheets, rope, tape, cloth and tubing are flexible, fire-resistant fabric products used in applications where flame and fuel resistance is required.

Most people enjoy theme parks as a place to get away from work, but for those in the hydraulics industry, they are a place to demonstrate their expertise. Behind many of the rides that make your stomach drop or your eyes blink in amazement, Parker's accumulators are picking up the stresses and enhancing the performances of hydraulic technology.
Behind the scenes, there is complex machinery that must run precisely and smoothly to ensure safe and reliable operation. Whether you are splashing through water, sailing above the tree lines, or being wowed by animations and simulations, powerful equipment that depends on the science and engineering of hydraulics is enriching your activities. And, many of these large, powerful hydraulic systems rely on accumulators; hidden from the public view, but critical in their roles.
Typically, accumulators installed in hydraulic systems store energy to either provide an extra boost of power or absorb energy to smooth out pulsations. One of the world's largest manufacturer of accumulators is Parker's Accumulator and Cooler Division. According to Jeff Sage, product sales manager, the Parker accumulators used in theme parks are gas-charged and are either bladder accumulators or piston accumulators. Parker manufactures both types and has the engineering expertise to recommend which kind best fits the requirements of a particular ride.

Can electrically conductive plastics really replace traditional metal electronics enclosures? The answer is a resounding yes! There are very effective electrically conductive plastics available today that provide excellent electromechanical properties that help shield portable electronics from the electromagnetic interference (EMI) noise that is proliferating our daily life. Smart phones, Bluetooth, Wi-Fi, radio, even your television are all susceptible to EMI. So here are the key points you may want to consider when evaluating electrically conductive plastics for your application:
Every day we encounter EMI, and sometimes it happens at the most inopportune time. Maybe you’ve been put on hold for an hour and just when the customer service agent gets back to you, your cell phone drops the signal. Or perhaps you’re blasting the car radio listening to your favorite song, and just when the chorus comes on, static noise drowns out the tunes as you drive under high tension power lines. These are all examples of EMI interfering with our daily life, and electrically conductive plastics can help shield our portable devices from these interruptions.

Increased emission restrictions are requiring engine manufacturers to conform to Euro 6 and Tier IV regulations to reduce exhaust leakage 80% or more. In order to achieve these new standards, engines with extreme temperatures coupled with a high amount of vibrational movement, need to have highly engineered sealing solutions. Applications with predetermined mating components cannot always be changed, so the need for a sealing solution with a similar coefficient of thermal expansion is needed.
Most heavy duty diesel engines can reach exhaust gas temperatures upwards of 1292°F(700°C) while subjected to constant vibrations. These engine vibrations can cause havoc when a seal needs to be maintained on the exhaust line. Vibrations from the engine cause rotation, cavity offsets, pivoting, and reciprocation which become difficult to seal against. Movement, pressure cycling and thermal cycling require an engineered solution to maintain a seal under extreme application conditions. With the use of custom engineering and advanced analysis techniques, Parker is able to create custom solutions for our customers’ most difficult applications.

Elastomer seals from Parker Prädifa meet the most exacting demands in a wide range of applications. Aside from the appropriate seal designs, the material properties of the seal compounds are crucial to ensuring that seals deliver the desired performance.
A key criterion for the storage period of elastomers is the time at which the product was vulcanized. Parker indicates the date of manufacture on the packaging bags: “1Qxx” stands for parts produced in the first quarter of the year 20xx. The recommended maximum storage period depends on the type of elastomer.
