Air Compressor Pump Replacement, NS18 Complete Assembly with Aftercooler, Single-Stage, 3 - 5 HP #05C177

NS18S Air Compressor Pump Replacement, Complete Assembly with Aftercooler, Single-Stage, 3 - 5 HP. Same as B3800 except it includes aftercooler and flywheel. Aftercooler must be used.  

Important: This pump has a LEFT-side discharge. If your discharge tube connects to the right side of the pump head you can simply remove the head bolts and lift the valve plate assembly and head as one piece and flip it 180° so that the discharge is on the right side of the head.

Note: For Kobalt models, the NS18S pump is only used on models K7045V and K7060HFV.

If this is replacing your old pump that has part number 3700066SNO056, this pump is shorter than the original but it will install properly. To complete the repair you need to order a new Discharge Tube and Elbow, part number DT031L.
