The CKM knuckle joint swab was designed for optimum field performance with rapid access to the swab cups. This three-piece swab mandrel has the heaviest payload of its class running 4 1/2" cups. We offer a sleeve specifically designed for the CKM swab mandrel in order to run 5 1/2" cups. The only threads are on the top sub thus eliminating rig down time to chase pipe threads familiar on other manufacturer's swabs.
