Common Compressor Connections

Where Flexible Metal Hose Is Typically Applied

Compressor OutletCompressor outlet to receiver or rigid discharge piping.Review heat and vibration
Aftercooler & DryerFlexible connections around aftercooler and dryer equipment.Review temperature and geometry
Skid-Mounted EquipmentConnections where vibration and equipment movement must be isolated from rigid piping.Review support conditions
Industrial Connection TypesThreaded, JIC, welded, or flanged ends depending on the equipment and system requirements.Match field interfaces

Published configuration prices do not replace application review.

Corrugated metal hose must not be installed in torsion or used as an unsupported, continuously flexing line. Compressor pulsation, discharge temperature, pressure, braid loading, minimum bend radius, live length, and anchoring must be reviewed for the actual installation.
