The Snap Latch Stinger Sub are used when well conditions make it difficult to pull the necessary two inches required for tubing testing without stinging out of the retainer. These stinger subs are designed to positively lock the stinger sub into the retainer while allowing valve actuation with up and down motion.

The Stinger Subs will not lock the retainer valve into the open position. Hydraulic effects must be considered to ensure the valve will remain open during pumping operations.
