Milwaukee Grease Gun Coupler Assembly
Model Number: 42-90-0065
The Milwaukee 42-90-0065 is a genuine OEM Grease Coupler Assembly for the Milwaukee M18 Grease Gun 2646-20, 2646-21CT, and 2646-22CT. The grease coupler is the metal fitting that attaches to the end of the grease gun hose and connects to standard Zerk (grease) fittings on machinery, vehicles, and equipment to deliver grease under pressure. The coupler must form a secure, leak-free connection with the Zerk fitting — typically through a snap-on or push-on locking engagement — to ensure grease is delivered to the lubrication point without loss and to contain the high pressure generated by the grease gun during operation. A worn, damaged, or leaking grease coupler that can no longer form a tight connection with Zerk fittings or allows grease to escape at the coupling point requires replacement to restore efficient, mess-free grease delivery.
Using a genuine Milwaukee OEM grease coupler assembly ensures the correct Zerk fitting engagement geometry, pressure rating, and hose thread connection for the M18 Grease Gun it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct coupler for your specific unit.
