Crown Industries CG318H Gas Connector 3/8x9/16x18

Product Description

The CROWN INDUSTRIES CG318H is a gas connector designed to create a flexible, secure connection between a gas supply line and an appliance. This fitting spans 18 inches in length with a 3/8-inch inlet and a 9/16-inch outlet, making it suitable for residential gas piping applications where a short, flexible run is needed. Gas connectors of this type are installed by licensed plumbers and HVAC technicians during appliance hookups and service calls. The CG318H bridges the rigid gas supply stub-out to the appliance connection point, accommodating minor positional offsets and reducing stress on fixed piping.

This connector is used in residential and light commercial settings where a gas appliance requires a flexible supply connection. Typical applications include gas ranges, dryers, water heaters, and space heaters connected to natural gas or propane distribution systems. It is commonly specified when replacing a worn or non-compliant connector during appliance installation or appliance changeout work.

Key Features

• 18-inch flexible length provides clearance for standard appliance positioning
• 3/8-inch inlet fitting for connection to the gas supply stub-out
• 9/16-inch outlet fitting for connection at the appliance end
• Designed as a flexible gas connector for short, direct appliance hookup runs

Compatibility

Installation Notes

Gas connector installation must be performed by a licensed plumber or qualified gas technician in accordance with local codes and the International Fuel Gas Code (IFGC). Shut off the gas supply at the nearest shutoff valve before disconnecting or installing any gas connector. Inspect all threaded connections with an approved leak-detection solution after installation before restoring gas service. Never route a flexible gas connector through walls, floors, or ceilings, and do not use the connector to make up for excessive distance between the supply and appliance.
