Description

B5900 Two-Stage Air Compressor Pump Replacement. Includes flywheel, aftercooler, and air filter assembly.

Note: If your old B5900 does not have an aftercooler, please purchase the B5900AAK Aftercooler Adapter Kit. The aftercooler outlet measures 1-1/4" FPT, 

Also order a bushing (part number BLBS1250X0750) to reduce the 1-1/4" female NPT fitting in the bottom of the aftercooler to 3/4" female NPT.

If you need to further reduce the 3/4" female NPT thread to a 1/2" female NPT thread, then order part number BLBS0750X0500.
