  1. Self-Fusing Silicone Tape

    Self-Fusing Silicone TapeSelf-fusing silicone tape from Freudenberg Sealing Technologies is made of a specially formulated silicone rubber capable of fusing to itself to create a flexible, homogeneous barrier. The tape starts to tack within seconds, forms an air and water tight seal within minutes, and permanently fuses to itself within 24 hours.

    Self-fusing silicone tape contains no adhesive, which makes for residue-free installation and removal. And unlike traditional adhesive based tapes, it can be applied to surfaces that are wet or dirty without any impact on performance. It has excellent dielectric strength, ozone resistance, high and low temperature stability and moisture resistance.

  2. Extruded and Spliced Seals from Parker

    extrudedParker’s precision extruded and spliced seals offer an ideal, cost effective sealing solution for many applications.

    Their spliced products include hollow low-closure force seals, large diameter rings that cannot be molded, “picture-frame” gaskets and custom configurations for non-standard grooves. Rings are available in a wide range of sizes with capabilities for very tight tolerances.

    Customers can choose from a large variety of profile cross-sections and different material technologies. Parker’s superior vulcanization technology offers high bond strength, uncompromised chemical resistance and consistent flexibility.

  3. PEEK and PAI Thermoplastics

    PEEK and PAI ThermoplasticsTransmission development is a focus for emissions reduction.  Dual-clutch transmissions or automatic transmissions with eight or more gears not only increase the efficiency of the drivetrain but also create new challenges.

    Higher load generation is one major challenge of dual-clutch transmissions and seals from Freudenberg Sealing Technologies made from PEEK (polyetheretherketone) or PAI (polyamideimide), in conjunction with their low-torque design, are a dependable solution to high load pressure.  And Gallagher is proud to be your Freudenberg Sealing Technologies distributor.

  4. More Common Reasons For O-Ring Failure

    O-Ring failure
    O-Ring rubber

    A few weeks ago on this blog, we discussed a few of the common reasons for O-Ring failure.

    Typically, O-Rings fail due to adverse effects of a number of factors, from improper installation and lubrication to incorrect size and design.

    Today we’ll continue that discussion by looking at three more reasons why O-Rings fail, along with ways to identify and correct these failures.

  5. Fabric Reinforced Products: Durable, Flexible and Fire Resistant

    fabric reinforced productsToday’s aerospace, heavy duty and industrial markets are constantly pushing the boundaries of performance in their products. Parker Hannifin’s Composite Sealing Systems Division is working directly with manufacturers to provide industry leading tensile strength, pliability, and fire resistance.

    Parker is able to achieve these requirements by expanding their product offerings with fabric coated or infused rubber. Reinforcing an elastomer with fabric increases the durability and longevity of a part along with added flame and abrasion resistance.

    Much like Gallagher, Parker Hannifin continues to expand their product offerings to help customers meet the demands of a constantly evolving world.

  6. Continuous Molding Technology Enhances O-Ring Performance

    continuous molding technologyHistorically, technology to produce large diameter molded O-Rings has been limited by press and molding capabilities. One of Gallagher’s premier vendors, Parker Hannifin, has created a proprietary continuous molding technology which ensures the strength and reliability of large diameter FKM, HNBR, NBR and EPDM O-Ring seals. Parker’s solution eliminates the sealing performance problems sometimes found with common spliced rings and serpentine molding methods.

  7. Reduce Fuel Consumption and CO2 Emissions with the Low Friction Simmerring

    Low Friction SimmerringFreudenberg’s Simmerrings seal rotating shafts reliably and are used in millions of applications and with a variety of equipment in general industry and the automotive sector.

    This radial shaft seal ring is based on know-how gained from years of experience. It continually undergoes further refinement based on the latest technological developments, and is particularly functionally reliable, flexible and extremely stressable.

    Always “up-to-date”
    The tried-and-tested original Simmerring keeps up with the times. Freudenberg’s experts have continued to develop it, with improvements in seal lip profiles. This has made it possible to further enhance its reliability and functionality across a broad range of applications. The advances include a friction-optimized design – the Low Friction Simmerring® – to decrease fuel consumption, which leads to reductions in CO2 emissions.

    Gallagher Fluid Seals offers a comprehensive selection of Freudenberg Sealing Technologies products suited to a variety of requirements.

  8. Drop-in-Place Seals

    Drop-in-place seals offer easy installation and time-savingdrop-in-place seals assembly, providing seal retention in straight-wall or dovetail grooves.

    Gallagher and the Parker ISS Division design each drop-in-place seal with the application in mind, taking into consideration the material and manufacturing process of the mating surfaces to determine the most efficient design.

    The drop-in-place design utilizes a rubber encapsulated plastic or metal backbone, lined with retention and stabilizer ribs. This design holds simple or complex seal shapes, easing installation and providing automation possibilities. Small contact points require less flange loading, providing maximum sealing under minimal pressure for non-ideal surfaces.
