Milwaukee High Flow Coupler Service Kit with Plug
Model Number: 42-90-0026
The Milwaukee 42-90-0026 is a genuine OEM High Flow Coupler Service Kit with Plug for the 2774-20 M18 FORCE LOGIC 10,000 PSI Hydraulic Pump. The high flow coupler is the hydraulic quick-connect fitting at the pump's outlet: the hydraulic hose for a connected tool, such as a knockout tool, crimper, or cutter, couples to it, and the pump's high-pressure hydraulic flow passes through it to drive that tool. This kit supplies the high flow coupler, its coupler plug, and the o-ring that seals the connection, so it provides the complete coupler and its sealing parts together. Because this coupler operates at up to 10,000 psi (700 bar), it is a safety-critical, high-pressure component: only couplers rated 10,000 psi or higher may be used on this pump, and a worn, leaking, or damaged coupler must be replaced with the correct OEM part, not a lower-rated substitute. Using the genuine Milwaukee OEM kit ensures the correct high-pressure rating, thread, and seal for this hydraulic system.
This kit is identified as the High Flow Coupler Service Kit with Plug, Figure 88, on the Milwaukee service parts list for the 2774-20 M18 FORCE LOGIC 10,000 PSI Hydraulic Pump, serial K15A, bulletin 54-00-2774, and it consists of the coupler plug, the high flow coupler, and the o-ring (34-40-2774). Before servicing the coupler, always relieve the hydraulic pressure: remove the battery pack, then push and hold the manual pressure release button for five seconds. To replace the coupler, steady the coupler swivel with one wrench while loosening or tightening the coupler with a second wrench, clean any old teflon tape from the swivel, apply only teflon tape to the coupler threads (about two wraps), and torque the coupler to 45 to 55 lb-ft. Because Milwaukee specifies service parts by serial number as well as catalog number, verify your catalog and serial number against the official Milwaukee service parts diagram before ordering, since running production changes can alter part compatibility within the same catalog number.
