Ridgid 18068 Air Compressor Pump is the OEM replacement pump assembly for Ridgid GP90135 wheelbarrow-style gas-powered air compressors. It is used on GP90135 as well as GP90150 and GP90150A models, and the pump is oil-lubricated, requiring about 12 ounces of oil for lubrication. This pump assembly is designed to replace a worn or failed GP90135-series pump, restoring the compressor’s original air output and performance.
