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

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.

GORE® GFO® Fiber products meet the definition of an article; therefore, a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) is not required. However, for your convenience, a Product Safety Sheet, which details the intended use and proper handling of our articles, is provided.

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 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.
