Nitrogen Tire Inflation System - 20Cu

Part# 12-01586


Note: Per vendor, the included CGA580 tank is DOT & TC Approved.


GENTECŪ Nitrogen aircraft tire inflation systems allow for easy, cost effective filling of General Aviation aircraft tires with pure Nitrogen.

Due to the complex nature of construction and the severe operating conditions of aircraft tires, Michelin and other leading tire manufacturers recommend the use of Nitrogen as does the FAA.

Nitrogen is a totally inert gas that will not support corrosion or oxidation within aircraft wheels and tires.

Compressed Nitrogen has a larger gas molecule than compressed air, so low tire pressure due to allowable leakage is minimized. Gentec Nitrogen aircraft tire inflation systems are available in two versions.

The GKNAT20-TC: 12-01586 is a 20 cubic foot high pressure nitrogen tank (empty) with stand, ten foot hose; pressure reducing single stage regulator and tire inflator with resetable dial pressure gauge.

Bottle was not new. But it didnt matter as the Airgas supplier swaps the bottle anyway. Might have been cheaper to just buy valves and components from them. Still everything worked well and the gauges were cross checked and were accurate.
