CO & CD Knuckle Jar Assembly
CO Knuckle Jar (Threaded)
The Rebco CO Knuckle Jar is similar in design to the standard knuckle joint but incorporates an extended socket that allows the ball to travel vertically through a short stroke, providing a light jarring action in addition to the angular flexibility of a standard knuckle joint. This dual function makes the knuckle jar particularly useful for bottomhole pressure (BHP) work and light-duty wireline applications, where tool string flexibility and light jarring capability are required in a single component. Available in 2", 4", 6", and 8" stroke options, in standard threaded connections, 1¼"–2½" OD.
CD Knuckle Jar (RQLD)
The Rebco CD Knuckle Jar is the RQLD quick-lock version of the Rebco CO, delivering the same dual-function flexibility and light jarring capability with the speed of Rebco's double-shoulder Quick Lock System connection. Available in RQLD connections, 1¼"–2½" OD.
