Understanding basic compression packing installation steps is key to getting the job done right, and will ensure outstanding packing performance.

Compression packing has been around since the beginning of the industrial revolution and is still used extensively in types of equipment in which a stuffing box seal is required to prevent loss of process fluids to the environment. While advanced sealing solutions for rotary applications, such as mechanical seals, emerged over time, compression remains an important industrial tool.

For more than 40 years, the Sealant Technologies Group of W. L. Gore & Associates has fostered a solid knowledge of factors that influence the sealing of piping systems, vessels, pumps and valves. Our singular focus has resulted in the development of innovative and top-performing gaskets and packings. We’ve also established a comprehensive technical services program, specially designed to help customers determine the best solutions for their toughest sealing applications.

To demonstrate how well GORE^® GFO^® Fiber Packing performs in service, W. L. Gore & Associates has conducted many field trials in a wide range of applications and industries.

The results of these tests have been compiled and are presented in this booklet to help the user weigh the relative value of GORE^® GFO^® Fiber Packing as compared with that of alternative materials.

Proven High Performance: Packings containing 100% GORE® GFO® fiber give maintenance engineers consistently high-performing general service packing for wide application and use. Unlike other PTFE/graphite packings, only those made with GFO® fiber, with its 30-year history of trouble-free performance, deliver unmatched level of assurance and confidence.

Compression packing has been around since the beginning of the industrial revolution. It is still used extensively today in equipment where plant operators understand the advantages of managing the warning signs of a degrading pump packing versus sudden failure mode of mechanical seals. Experienced operators know to watch out for tell-tale signs of packing degradation, such as an increase in flush water use, the need for gland follower adjustments, a hot running or even a smoking pump.
