Repair Parts for the Craftsman model 921.16475, WPB1982513 Portable Single-Stage Oil-Bath Electric Air Compressor

NOTE! This unit uses the "130" model pump.

If ordering a new 130 Pump, you can use the Head from your original pump, as it will retro-fit onto the new Pump. This is necessary for older pumps that have two outlets in the head; the new pump Head only has one outlet in the head.
