GAS SUPPLY COUPLING FOR A WATER HEATER
A gas supply coupling includes a gas supply line receivable in a telescoped relationship with a fitting to define an interface section. A crimp ring is received at least partially over the interface section to provide a metal-to-metal seal between the fitting and the gas supply tube.
1 . A gas supply coupling comprising:
a fitting;
a gas supply line receivable in a telescoped relationship with said fitting to define an interface section; and
a crimp ring received at least partially over said interface section to provide a metal-to-metal seal between said fitting and said gas supply tube.
2 . The gas supply coupling as recited in claim 1 , wherein said gas supply line is receivable into said fitting.
3 . The gas supply coupling as recited in claim 1 , wherein said fitting is receivable into said gas supply line.
4 . The gas supply coupling as recited in claim 1 , wherein said gas supply tube is flexible.
5 . The gas supply coupling as recited in claim 1 , wherein said crimp ring includes a ramped inner surface.
6 . The gas supply coupling as recited in claim 1 , wherein said fitting includes a gas control device.
7 . The gas supply coupling as recited in claim 6 , wherein said fitting includes a valve.
8 . A method of assembling a gas supply for delivering combustion gases to a device comprising:
telescoping a gas supply line with a fitting at an interface section; and
connecting the gas supply tube and the fitting with a crimp ring at the interface section.
9 . A method as recited in claim 8 , wherein the crimp ring provides a metal-to-metal seal.
10 . A method as recited in claim 8 , wherein the crimp ring provides a permanent joint between the gas supply tube and the fitting.
