10 Pneumatic Tyre Union For Drilling Pipe Sealing System

10" pneumatic tyre union for drilling pipe sealing system Seal o grip union ( air o union ) are air-inflatable connections 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-right seal is achieved with rig supplied compressed air, even if the connecting pipe is not perfectly aligned. The oil and abrasion resistant NBR pneumatic o 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.  Main Features. 1) Low requirement to centered when installed, to achieve quick install and seal. .  2) The pipeline can be removed without other tools after pneumatic union deflated, adaptable and easy maintenance.  3) No wrenches, bolts & nuts required.  4) Fast and easy make up without close alignment.  5) Allows pipe expansion or misalignment without breaking the seal. .  Order No. Size Mold HX-PU-004 4" Steel Shell + Air O Tube HX-PU-006 6" Steel Shell + Air O Tube HX-PU-008 8" Steel Shell + Air O Tube HX-PU-010 10" Steel Shell + Air O Tube HX-PU-012 12" Steel Shell + Air O Tube HX-PU-014 14" Steel Shell + Air O Tube HX-PU-016 16" Steel Shell + Air O Tube
