The MILWAUKEE® Locking Grease Coupler delivers easier zerk connections for heavy-duty greasing applications, giving users the freedom to pump without needing to hold the coupler onto the zerk. Designed for use with 3646-20, 2646-20, and 2446-20, this coupler supports the M18 FUEL™ Grease Gun, M18™ Cordless 2-Speed Grease Gun, and M12™ Cordless Grease Gun, and may be compatible with competitive grease guns. Its flat knurling thumb pad design helps prevent a finger from slipping off the coupler, while 6 jaws provide a more secure zerk connection to help prevent leaking. The narrow coupler design allows for better access to recessed zerks, supporting controlled operation in confined service points. Built for use with the M18 FUEL™ Grease Gun, M18™ Cordless 2-Speed Grease Gun, and M12™ Cordless Grease Gun, this coupler supports the Milwaukee® M18™ and M12™ systems.
