Purpose and core function Connects your home's natural gas supply to a gas appliance using a quick-connect coupling. Provides a fast, reliable link between the house gas line and the device for installation, service, or temporary connections. Key benefits Built-in automatic shutoff: the connector closes gas flow immediately when the hose is disconnected, reducing leak risk and improving safety during maintenance or appliance swaps. Time-saving and convenient: quick-connect/disconnect design speeds installation and reduces the need for tools, making routine service and appliance changes faster. Reliable connection: consistent mating with the correct 3/8 inch fittings improves connection reliability and flow control. Compatibility and important limits Intended for use with household natural gas supply and appliances. Fitting size: designed for 3/8 inch fittings. Do not use directly with low-pressure propane until you have an adapter to convert 3/8 inch fitting on BBQ to 3/8 inch pipe fitting. Performance and practical notes Automatically shuts off flow on disconnection to minimize gas release. Suitable for situations where repeated connections/disconnections are required or where quick, tool-free servicing is needed. Typical use scenarios Installing or servicing a natural gas range or cooktop where a secure, quick-disconnect is needed for access. Connecting a natural-gas-fired heater, water heater, or portable appliance during maintenance or temporary use. Hooking up an outdoor grill converted to natural gas — or using a propane grill only after fitting it with the required adapter to convert 3/8 inch fitting on BBQ to 3/8 inch pipe fitting. Safety reminder Follow appliance manufacturer instructions and local codes for gas work. Verify you have the correct adapter and fitting type before using with propane equipment.
