A heat-dissipating extender is provided in a joint between a sealed-gas burner having a burner fitting and a gas supply tube having a tube fitting. The heat-dissipating extender includes a body having a first end, a second end, and an interior passage extending between the first end and the second end for passage of the gas from the tube to the burner. The first end has a first fitting interfitting with the burner fitting to provide a seal against leakage of fluid pressure. The second end has a second fitting interfitting with the tube fitting to provide a seal against leakage of fluid pressure. The body is adapted for dissipating heat to provide a substantial temperature differential between the first end and the second end when heat is applied to the burner fitting at the first end during operation of the burner so that the tube connection at the second end remains sealed. The extender is formed from a material having a low thermal conductivity such as stainless steel and has a plurality of grooves to form radially extending ribs.
