Seal o grip union ( air o union )Â are air-inflatable connections for low pressure fluid or mud suction and return e 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.Â
1) Low requirement to centered when installed, to achieve quick install and seal. .Â
2) The pipebe removed without other tools after pneumatic union deflated, adaptable and easy maintenance.Â
3) No wrenches, bolts & nuts required.Â
4) Fast and easy make up without close alignment.Â
5) Allows pipe expansion or misalignment without breaking the seal. .Â
