Garlock
- December 04, 2018
In the late nineteenth century, Olin J. Garlock devised a better way to seal piston rods in steam engines. Since then sealing materials have been developed for various industrial applications. Over the years, different manufacturing processes such as calendering and beater addition have improved the performance of fiber sheet gaskets for these applications; however, design concepts for their formulation remain similar regardless of manufacturing method.
OVERVIEW OF MATERIALS
Many of the applications for compressed fiber sheet gaskets involve elevated temperatures and/or high pressure, which require high bolt loading in flanged joint assemblies. Various materials are added to the fiber-binder matrix to sustain this high compressive loading. To provide strength, different types of fibers such as p-aramid (Kevlar™), cellulose, polyester, glass fiber, carbon fiber, and others are added. Some of these fibers are organic materials, which limits their use at elevated temperatures. Minerals in cylindrical form provide balance in the formulation due to their high-temperature stability and strength. To form a compact structure, materials of different sizes are used, including silica, carbon black, and other micro-sized fillers. Figure 1 illustrates the ingredients and microstructure of a compressed fiber sheet material.

KLOZURE® Oil seals from Garlock® KLOZURE® are available in a wide variety of configurations to meet the requirements of major industries. MILL-RIGHT® materials are used on all elastomeric seals for superior bearing protection. KLOZURE® Oil Seals are available in more than 50 different styles in sizes from ¼" to over 90", solid or split, metal-cased or all-rubber. KLOZURE® Oil Seals have had a strong brand presence in the U.S. since the 1920’s. Today they are also manufactured and branded in China and Germany. Technology has advanced over the years, and the oil seals are now available in MILL-RIGHT® elastomers which provide longer service life than their predecessors.
There are many different styles and variations available from Garlock® KLOZURE®, but below are some of the more popular oil seals.

Gallagher recently added the GYLON EPIX™ Webinar to its website. This video is a recorded webinar discussing GYLON EPIX™ - The Next Generation in PTFE Gasketing.
This material is a newly developed family of PTFE gaskets. It is manufactured using a patented, profiled surface based on our proven Fawn (Style 3500), Off-White (Style 3510), and Blue (Style 3504) GYLON® to create highly conformable materials for optimum sealing performance.
GYLON EPIX™ will provide superior functional performance by combining the traditional attributes of GYLON® with an innovative surface design. It offers a broader range of applications than traditional PTFE gaskets that are used in worn and pitted flanges. In addition, GYLON EPIX™ delivers the tight sealing and load retention properties of 1/16” (1.6mm) and the conformability of 1/8” (3.2mm).

THE EPIX™ DIFFERENCE
GYLON EPIX™ and a traditional full face gasket were installed in a 3”-150# flat face flange at 120 ft.lbs. with pressure sensitive film. The film revealed that the traditional material saw heavier loading-near and around the bolts, and lighter loading at the points furthest from the bolts. The GYLON EPIX™ was able to distribute the load more evenly and prevent the low loading phenomenon.
The pressure sensitive film was then analyzed with special software that translate the various shades of red into a full color spectrum that provides a better visualization of the stresses that were developed on each of the gaskets. Again, while the traditional gasket saw areas of lower stress (green and blue areas), the hexagonal pattern in the GYLON EPIX™ concentrated and distributed the stress more evenly across the entire gasket.
