Compression Packing

Compression packing is the oldest and most common means of controlling fluid loss in mechanical equipment, which is essential to its successful operation. Made from relatively soft, pliant materials, compression packing finds major use in rotary centrifugal and reciprocating pumps valves, expansion joints, and several other types of mechanical equipment. We offer flax, PTFE, Kevlar, and expanded graphite compression packing that is used to control leakage at shafts, rods, valve stems, and other functional parts of equipment requiring the effective containment of liquids and gases.
