Overview Product Description

The Tubing Drain allows for the tubing string to be drained prior to tripping, avoiding problems associated with pulling a "wet string". 

The Tubing Drain's shear value is easily adjusted by simply adding or removing shear screws. The Tubing Drain is activated by putting sucker rod to shear the shear pins and open the large drainage ports to the annular space above the pump. 

The drain should be run box up and pin down at the desired depth in the tubing string.
 Use only the minimum number of screws required in order to avoid over pressuring the tubing.
All Tubing Drains are made from high quality Alloy material and use brass shear screws. Replacement parts for all components are available from stock.Product Parameters
