The MILWAUKEE 42-90-0115 is a male coupling designed as a replacement part for Milwaukee power tool assemblies. Couplings of this type connect fluid or air lines within tool systems, maintaining a secure, leak-resistant junction between components. This part is sourced directly from Milwaukee's parts and accessories line, making it suitable for technicians and service professionals performing maintenance or repair on compatible Milwaukee equipment.
This male coupling is intended for use in service and repair scenarios where the original coupling has worn, cracked, or failed. It fits within Milwaukee's power tool parts ecosystem and is typically installed by tool repair technicians or service center personnel responsible for restoring equipment to operational condition.
Designed as an OEM-style replacement male coupling for compatible Milwaukee power tool assemblies. No specific model compatibility data was provided in the source information.
Installation should be performed by a qualified tool repair technician familiar with Milwaukee power tool service procedures. Disconnect and fully de-energize the tool and relieve any line pressure before removing or replacing coupling components. Use appropriate hand tools to avoid over-tightening, which can damage threads or sealing surfaces. Refer to the applicable Milwaukee service documentation for this tool assembly before proceeding.
