DESC: The kit contains a standard 22-inch, rubber hose. The regulator features a large, plastic knob that users manually screw counterclockwise onto QCC1 connection style tanks for a factory seal. Affixing the regulator to the tank requires absolutely no tools, while use of articles such as a screwdriver may cause damage. When attached properly, users may notice a gentle whistle or a hum as a result of the full tank, barometric pressure, or humidity. An air vent on the regulator also releases a hissing sound as air circulates. Such sounds are absolutely normal unless accompanied by the scent of gas. Grill owners in rural environments or with pets may opt to purchase a wire hose guard to prevent animals from chewing through the hose.
