The Model “R” Profile Nipple is a BOTTOM NoGo Nipple that provides for the location of various wireline flow control devices in the production string.

The “XO/XD” Circulating Sleeve provides a convenient way to establish or shut off communication between the tubing and the annulus. Any number of these sleeves may be run in a tubing string, and any or all of them may be opened or closed in one run by standard wireline methods.

The “XA” Circulating Sleeve provides a convenient way to establish or shut off communication between the tubing and the annulus. Any number of these sleeves may be run in a tubing string, and any or all of them may be opened or closed in one run by standard wireline methods.

The “L” Circulating Sleeve provides a convenient way to establish or shut off communication between the tubing and the annulus. Any number of these sleeves may be run in a tubing string, and any or all of them may be opened or closed in one run by standard wireline methods. This Circulating Sleeve can be used for gas lift.

The T-2 On-Off Tool is a tubing disconnect device that has an internal blanking plug locking profile with seal bore for utilizing flow control equipment. The Overshot has a box looking up, which connects to tubing string, and a pin looking down off the Stinger, which connects to the packer. The T-2 On-Off Tool has two basic components that comprise the Overshot. The Top Sub, which contains two bonded rubber steel seals and the Jay Latch which has a J Slot configuration to locate and latch the On—Off Tool Stinger. The Jay Latch also has a wash over shoe configuration which allows cutting through debris. The Overshot automatically Jays up on the Stinger, when lowered into the well.

The PX Plug is a device capable of holding pressure differentials, from above or below,when set at any X Profile Nipple of the same size.

FB-2平衡阀又叫固定阀，它可以阻止它上方流体向下流动，允许它下方流体向上流动。可用作打压球座。坐落在相应的F型坐落接头中，没有锁定结构，靠平衡阀上方的压力把它锁住。在回收前用回收工具向上震击，剪断销钉，平衡上下压力。投放工具：C-1型送井工具回收工具：SB送井/回收工具
