Rolair FC046001000 Unloader Tube

Rolair FC046001000 Unloader Tube is a 9-inch nylon discharge tube that forms a key part of the unloader assembly on select Rolair portable compressors. Identified by FC046001000, this tube is designed for use with FC2002-series units such as the FC2002 and FC1500HBP2, and is typically paired with the 011077000F ring to secure the connection. The tubing measures 0.75 inches in nominal diameter and 9 inches in length, providing a durable, heat- and wear-resistant link in the compressor’s unloading pathway. When used with the unloader valve, the tube channels air to the discharge path during unload cycles to relieve tank pressure and facilitate reliable restart. Rolair’s parts documentation lists FC046001000 as the Nylon Tubing – 9” component for FC2002 configurations, confirming its role as a targeted replacement part within the FC2002 FC1500HBP2 family of compressors.
