Reduce Standard Groove Size with Parker Diamond Seals+

Parker Diamond SealsParker Diamond Seals are designed to be a compact, robust axial seal alternative to standard cross section seals. Their unique design allows for reduced compression forces, making them ideal for small, lightweight housings in aerospace and military applications.

Narrow cross section
With a tall and narrow diamond-like cross section, the diamond seal groove is 60% narrower than traditional grooves for comparable seal heights. The narrow cross section of the seal allows it to be used in tight corners and around small holes. The groove width savings allows housing to become thinner, reducing the weight assemblies and is less expensive to machine when compared to standard grooves.

What Springs Do Spring Energized PTFE Seals Use?

Metal spring

Spring energized PTFE seals use one of three different types of springs to energize the jacket. When choosing a spring design, consider two elements: load value and deflection range.

The spring’s load affects its ability to seal, friction, and wear rate. As the load increases, the lips seal tighter, while friction and wear increase proportionately.

The deflection range affects the seal’s ability to compensate for variations in gland tolerances and for normal seal wear. Each spring size has a specific deflection range. The available deflection increases as the seal and spring cross-section grows. This increase could be a deciding factor in choosing a cross-section. Use springs with a wide deflection range when sealing surfaces are not concentric. Continue reading What Springs Do Spring Energized PTFE Seals Use?

Gallagher Provides Training to Customers (CEUs available!)


CFO to CEO: “What happens if we invest in developing our people and then they leave?”

CEO to CFO: “What happens if we don’t, and they stay?”

Freudenberg Micro Simmerring & the Miniaturization Trend

Freudenberg Micro SimmerringThe trend of miniaturization has been growing for many years. Not only electronic, but also mechanical components are becoming more light-weight and smaller. The dependable sealing of micro systems poses major challenges in both the design and manufacture of the sealing components.

Freudenberg Sealing Technologies has recognized the positive trend of the future towards miniaturization and has risen to the challenges of this technology. The micro simmerring offers reliable sealing for shaft seals smaller than 3mm.

Freudenberg micro simmerring provides an optimal solution for sophisticated, customer-specific miniature applications such as micro pumps, micro drives and micro actuators. The micro simmerring has also proven its worth in a wide variety of micro systems in medical technology, in laboratory and diagnostic applications and in the general industry.

GORE Universal Pipe Gasket (Style 800)

Gore Universal Pipe GasketGORE® Universal Pipe Gasket (Style 800) provides a reliable seal for steel, glass-lined steel and fiber reinforced plastic (FRP) flanges, in the full spectrum of strong acid, alkali, and solvent process media, including the most challenging thermal cycling and elevated temperature applications.

This single gasket solution can reduce the process safety and production downtime risks caused by the use of an incorrect gasket material. Highly conformable 100% ePTFE reliably seals irregular surfaces.

What Makes the GORE Universal Pipe Gasket Unique?

  • Proprietary, patented technology.  GORE Universal Pipe Gasket (Style 800) uniquely combines two patented construction elements, each made of 100% expanded PTFE (ePTFE).
  • A non-permeable barrier layer covers the inside diameter and gasket flange faces, creating a tight seal at low gasket stress.
  • A conformable-yet-strong interior provides superior resistance to creep and cold flow.

Long-Term Reliable Sealing

Unlike conventional (filled and skived) PTFE, expanded PTFE (ePTFE) gaskets are highly conformable to common flange imperfections, creating a tight seal in challenging conditions.

With superior resistance to creep and cold flow, GORE Universal Pipe Gasket (Style 800) retains its dimensional stability through thermal and pressure cycles. Bolt load is maintained, to achieve a long-term reliable seal.

GORE Universal Pipe Gasket




One Gasket, Many Applications

The patented technologies of GORE Universal Pipe Gasket (Style 800) deliver a low stress-to-seal capability that is ideally suited for glass-lined steel and FRP piping systems, while maintaining the material strength required for outstanding performance in steel systems.

Chemically-inert GORE Universal Pipe Gasket (Style 800) provides a highly effective seal for strong alkali-, acid- and solvent-based chemical process systems. Made of 100% ePTFE, it is resistant to all media (pH 0-14) except molten/dissolved alkali metals and elemental fluorine.

GORE Universal Pipe Gasket (Style 800) creates a tight, reliable seal for multiple flange materials, so it can replace multiple other gasketing materials. By streamlining gasket ordering and inventories and standardizing the gasket selection and installation process, using GORE Universal Pipe Gasket (Style 800) across multiple pipe flange materials and process media reduces the process safety and production downtime risks from the use of an incorrect gasket material.
