The Thunderbird Aluminum SCUBA tanks are durable, reliable, and visually appealing. The tank is manufactured from the industry standard lightweight, high-strength aluminum 6061-T6 alloy. The 6 cubic foot tank is an ideal volume cylinder for use as a pony bottle, redundant air supply system, bailout or short duration decompression/safety stop gas supply. A pony bottle is a smaller tank, which is carried in addition to the main tank. It possesses its own regulator with first and second stage and sometimes a separate pressure gauge. It is mounted either at one's side or in front of the body or fixed to the main tank. A pony bottle scuba tank is the only true redundant breathing mechanism you can completely rely on.
The 6 cubic foot pony bottle has a 3000 psi (207 bar) service pressure rating, a capacity of 5.8 cu. ft. (0.8 liters), is negative 1.6 lbs. (0.7 kg) when full and is negative 1.2 lbs. (0.5 kg) at 500 psi (35 bars). Cylinder weighs 2.7 lbs. (1.2 kg) when empty, and measures (Dia. x L) 3.2" x 10.9" (81mm x 277mm). Aluminum cylinders unlike steel cylinders don't rust, they oxidize. The oxidization of aluminum forms a protective coat that hinders the continuation of corrosion making aluminum cylinders less likely to be condemned due to excessive corrosion. When shipped the tanks valves will be removed and the tank will require re-inspection before being filled.
Note:
All Thunderbird Aluminum cylinders are nitrox ready up to 40% and meet certificated specifications of the US Department of Transportation (DOT) with DOT-3AL specification and Transport Canada Safety and Security (TC) with TC-3ALM specifications. Purchasers should check with other country requirements to know if the cylinders are certified for use in that country.
Thunderbird's Valves are designed and manufactured for long life and heavy use. The Thermo by Thunderbird Pro Valve is no exception. Valve is made of marine grade brass with triple bright chrome plating for long life protection in salt water. Precision machined from high tension brass and chrome plated valve stems for years of service and corrosion free operation. The high-pressure seat is nylon. The Pro Valve will accommodate both Yoke and DIN regulators with its removable 230 bar (3,336 psi) DIN insert which can be removed using a 1/4" hex key wrench.
Easy grip soft rubber hand wheel with stainless steel insert ensures long life and large ribs make turning handle easy even when wearing gloves. Valve bonnets are copper crush washer sealed. Valve is equipped with a one-piece safety plug, has a 5/32" hex wrench dip tube for positive retention and 3/4" x 14 NPSM inlet threads which fit nearly all DOT aluminum and modern steel cylinders. All this and more makes this the valve of choice for the serious diver. The valve has a 3000 (200 bars) service pressure. Valve is Nitrox compatible up to 40%.
