SWR Snap J-Latch

When the Stinger enters the retainer bore, stop washing and set approximately 400 pounds down on the retainer. Rotate 1/4 turn to the left to jay the pin into the “LOCKED” position. The Snap Latch will then latch into Retainer and the slide valve will be shifted to the OPEN (in compression) position. In addition, the slide valve can now be opened and closed without accidently disengaging the stinger from the retainer.

The Snap Latch Seal Assembly may be released from the Cement Retainer by pulling 1,000 pounds tension at the tool and rotating 8 to 10 turns to the right. Alternatively the Seal Assembly can be released by setting down 1,000 pounds compression, rotating 1/4 turn to the right into the “UNLOCKED” position and snapping out with approximately 8,000 pounds tension force at the tool. Due note that each time the seal assembly is snapped out of the cement retainer, the snap out force is reduced.
