Hammer Unions are designed as heavy duty, high pressure flow line connectors. They are commonly found in chemical plants, on marine dredging vessels, in strip mines and in the oil industry. The colour coding system on Hammer Unions represent the different configurations and pressure ratings (Fig #'s are also normally stamped on the union as well); pressures range from 1,000-15,000 psi depending on the size and configuration. Never interchange different Fig Series, as threads may look similar, however the Series do not interchange.

Detail Comments: Fig 100: Used on low pressure manifolds, tank truck transfer, and in applications running air, water, oil or gas up to 1,000 psi non-shock cold working pressure.
