Typical Sizes of Finished Compression Packing

Braid Density

The yield figures below are representative of satisfactory braided packing made of 100% GORE GFO Fiber. The data serves as a working guideline only and not as a minimum quality standard.

Braid Dimensional Tolerances

Another significant factor affecting braided packing performance is the degree to which it is properly sized. Calendaring braid and die-forming rings are two effective ways that the manufacturer can produce packing that closely adheres to dimensional specifications. The Fluid Sealing Association recommends the following tolerances.

Cross Section Tolerance
To 1/4 in +/- 1/64 in
To 6 mm +/- 0.4 mm
1/4 in to 1 in +/- 1/32 in
6 mm to 25 mm +/- 0.8 mm
Greater than 1 in +/- 1/16 in
