Unions

 The Unions are air-inflatable connectors for low-pressure fluid or mud suction and return lines. The union carbon steel body welds in place on mud tanks or manifold pipe. A leak-tight seal is achieved with rig supplied compressed air, even if the connecting pipe is not perfectly aligned. The oil and abrasion resistant NBR pneumatic tube can be inflated up to 200 psi against the outside diameter of the connecting pipe, speeding field set-up and eliminating the need for low pressure flanged connections.
