ULTRA HEAVY DUTY DISCONNECT

The LiMAR® Ultra Heavy Duty Disconnect provides a hydraulic release mechanism with the maximum strength possible, suitable for heavy duty fishing operations with the most powerful Jars on the market.

The LiMAR® UHD Disconnect is activated by dropping a ball via the coiled tubing to seat inside the Disconnect Sub.
The coil is then pressured up to shear release screws within the Disconnect Sub. The pressure at which the tool is activated / released is determined by the number of shear screws installed leaving a standard GS internal type fish neck profile for future retrieval of the lower BHA section.
