Important Note

This is a special-order item. Confirm availability and lead time before ordering. Gas-path service must be performed by a qualified technician. Shut off the gas and follow the appliance service procedure, including the required leak test after installation. Do not force incompatible threads or substitute tubing based on length alone. Thread dimensions are not verified.

Why Choose This Part?

The defined 24-inch length and matching male end fittings make it straightforward to compare the replacement against the original tube and the specified service part.
