KEMPER UNION TUBE, 12 INCH SEAL-O-MATIC UNION,KEMPER, GRIP AIR UNIONS, DOUBLE STEEL UNION, ROUND SHAPE PNEUMATIC TYRE UNION

Pneumatic tyre union is widely used in the pipeline with low pressure, large drift diameter and misplacement, and frequent mounting and dismantling, particularly in the connection between the mud tanks of the solid control system in the petroleum sector.

Seal-O-Grip unions are air-inflatable connectors for low pressure fluid or mud suction and return lines. The Seal-O-Grip 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.

Fast, easy make-up without close alignment
Allows pipe expansion or misalignment w/o breaking the seal
