Pump and valve packing also referred to as compression packings or gland packings, provide an effective sealing solution for dynamic applications such as expansion joints, rotary, centrifugal, and reciprocating pumps, as well as valves.
Packing is made with soft, flexible yarns that are frequently created in braided structures. The inclusion of supplemental materials, such as extra lubricants and wire reinforcements, provides additional properties that are ideal for certain applications.
Compression packings are turned into rings and placed in the annular space between the rotating component and the body of the valve or pump. Compression packing is provided in preset lengths by the box. When the gland follower is reinstalled and tightened against the top packing ring, the “packing set” will compress, radially expanding the rings to form an effective seal between the body of the valve and the spinning element.

Pure Graphite – Lubricated
Pure graphite filaments lubricated with additional graphite and mineral oils. This results in a high performance packing with excellent capabilities in high speed dynamic applications. Resists almost all media. Temperature range of -240°C up to +430°C.
Injectable packing is a general purpose, water resistant option that is suitable for pumping into internal voids in valve and pump applications. This may remove the need for machinery strip downs, as opposed to typical compression packings above. Temperature range of -62°C up to +288°C.
