  1. Rod Seal Profiles, Performance, and Different Applications

    Rod Seals are the most important seal within any hydraulic sealing system.  Rod Seals prevent leakage of hydraulic fluid to the outside. Additionally, Rod Seals help contribute, in combination with a Wiper Seal, to preventing contamination of the environment.  GFS Rod Seal profiles are available as single acting (pressure from one side) or double acting (pressure from both sides). 

    This blog article will discuss the different profile, their recommended applications, and operating parameters.

  2. Speedi-Sleeve: The Fast and Easy Solution for Worn Shafts

    What is a Speedi-Sleeve?

    A thin-walled sleeve [0,28 mm (0.011 in.)], developed by our friends at SKF, is simply pushed in position over the worn area, fit tightly, providing a counterface surface that is optimized for radial shaft seals and typically harder than that of a new shaft.

    There is no shaft disassembly or machining involved and costly downtime is minimized. Since the same sized seal as the original can be used, there is no need to search for other seals, or keep a stock of different sizes. No special equipment is required since the installation tool is supplied with the sleeve. A mallet and a pair of pliers are all that is needed for the installation.

  3. Part 3: Your Glossary of Sealing Terminology

    Part 3

    For the sealing expert, the world of sealing terminology comes naturally.

    But for those who don't live and breathe seals every day, the list of terms can quickly become quite daunting.

    Thanks to our partners at Minnesota Rubber, this blog post will examine Part 3 of Sealing Terminology - the terms you may come across when looking for fluid sealing products.

  4. What are Clean-in-Place (CIP) Seals?

    Clean-in-place seals, or CIP seals, were developed to allow a seal to remain in place. This is especially important when the seal gland is partially open, allowing the seal to be flushed of debris.

    In a food application, the same chemicals used to clean or flush the system would be used to clean the seal gland. Similarly, when other products such as pharmaceutical or adverse chemicals needed to be flushed, the CIP seal does an excellent job being open to flushing.

  5. Basic Seal Engineering Guidelines

    o-ringsThe manufacturing and installation of specialty seals must be handled in a certain way to ensure their quality and longevity.

    The following guidelines and/or rules are the basics for regulating the engineering of seals to ensure top performance.

    Performance vs Knowing Your Seals

    The performance of your machine(s) depend on the quality of your seal and the conditions they succeed in. They can directly affect how well or how poorly your machines function. By extending the life and care of your seals, you can, in turn, extend the life of your equipment.

  7. Parker's Thermo-Chem - High Temperature Firewall Rope, Tape, Sheet, Cloth and Tubing

    Thermo-Chem

    Providing long heatsealing life with high conformability

    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.

    Their composition and construction from woven and texturized glass yarns, plain or wire-reinforced, form a non-porous, non-fraying, high tensile strength, firewall that offers long-term resistance to oils, solvents, vibration and abrasion. In addition, their flexibility enables them to readily conform to a variety of shapes.

  9. The Benefits of High Performance Metallic Seals in Critical Applications

    Failure is not an option in the most demanding sealing applications. Valves continually strain the capabilities of sealing solutions, and elastomer solutions are often not enough. The unparalleled reliability of high-performance metallic seals from our partners at Technetics can help excel in the face of these challenging scenarios.

    In these extreme environments, high-performance metallic seals combine state-of-the-art engineering with advanced materials design to deliver a product that exceeds expectations and stands up to the rigors of these applications.

    Why Use High-Performance Metallic Seals?

    Traditional sealing methods, such as elastomers or graphite seals, present limitations when extreme environments come into play. Under the tremendous workload of valves in these applications, they can lose tightness or deform, presenting distinct challenges.

  10. Parker's BRE Compounds Bridge Gap Providing Improved Properties Over FKM & Aflas®

    Fluids play a critical role in sustaining life. Keeping animals and humans hydrated and helping plants grow are obvious ways. Less obvious ways include moving cargo around the world and keeping equipment operating (hydraulic oils, coolants, engine oils, etc.). All these applications require seals of some sort ranging from public water systems to hydraulic pumps. What happens when these fluids become aggressive? People typically think of acids as being an aggressive media, but for many fluoroelastomers, bases are more aggressive presenting severe challenges.

    Using material science and technology, Parker has created a new class of Base Resistant (fluoro) Elastomer (BRE) compounds.
