Compression Packing

Compression packings, or pump & gland seals are used under a range of conditions to seal a variety of fluids. They are used to contain water, acids, solvents, gases, oil, and other chemicals that are subjected to various temperatures and pressures.

Compression packings are commonly used on valves, pumps and other rotary and reciprocating equipment.

Our standard range of compression packings are constructed of either x or square braids. They are used across a broad spectrum of industries including petrochemical, food & beverage, pulp and paper, and power generation.

They are resistant to a wide range of media across a temperature range from -200° C – + 1050° C.

See the summary table below for an overview of our most common packings.
