Description

The Imperial 1638 Compression Nut is a fastening component used in compression tubing assemblies to secure and seal 3/8" CCT or compatible tubing connections in commercial gas and plumbing systems. It tightens onto a compression fitting body to create a pressure-resistant joint without requiring soldering or flaring, forming a sealed interface between tubing and equipment connectors. This part is typically installed in commercial kitchen appliances, refrigeration systems and service line assemblies where controlled fluid or gas transfer is required. It operates within the connection system to maintain mechanical stability and sealing integrity at junction points related to service piping applications.
