Milwaukee Manifold Assembly
Model Number: 45-76-0037
The Milwaukee 45-76-0037 is a genuine OEM Manifold Assembly for the 2840-20 M18 FUEL 2 Gallon Compact Quiet Air Compressor. The manifold is the air-distribution heart of the compressor: it is the assembly that the compressed air from the pump feeds into and that manages, regulates, and distributes that air out to the air tool. This is a complete assembly that brings together the key air-management components of the compressor's output: the manifold body itself, the quick connector where the air hose attaches, the security valve that safely relieves excess pressure, the pressure gauge that shows the air pressure, the pressure switch that controls the compressor based on tank pressure, the two hose clamps and the 13 cm hose that connect it into the air system, and the regulator knob cover. Together these components take the air the pump builds and turn it into monitored, pressure-controlled, usable air at the outlet. Because the manifold carries pressurized air and contains the sealing surfaces, the safety valve, the gauge, the switch, and the coupler, a leak, a failed safety valve, a bad gauge or switch, or a worn coupler shows up as lost pressure, air leaks, inability to hold or regulate pressure, or a compressor that does not cycle correctly. Replacing it with the correct genuine Milwaukee OEM manifold assembly restores proper air distribution, pressure control, and safe operation.
Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee service parts diagram before placing your order, since running production changes can alter part compatibility within the same catalog number. This manifold assembly is specified for the 2840-20 M18 FUEL 2 Gallon Compact Quiet Compressor (serials L28A and L28B), so confirm your tool's catalog and serial number against the parts diagram before ordering. The pump motor, electronics assembly, tank, drain valve, and air filter are separate parts, so refer to your tool's parts diagram for the correct companion part numbers. Because this is a pressurized air component that includes the safety relief valve, follow the correct service procedure, make sure the compressor is fully depressurized and the battery removed before servicing, and ensure all connections are correctly seated and leak-free and the safety valve functions before returning the compressor to use.
