Tire Service Equipment Mfg. Co.’s NG-2 Nitrogen Tank Cart offers a less expensive alternative to tire service providers wanting to offer nitrogen tire service. Unlike the more expensive and traditional nitrogen generating systems, the NG-2 Nitrogen Tank Cart allows tire filling directly from a gas cylinder. Nitrogen gas cylinders are easily available and can be economically provided by any local industrial gas supplier. The portable NG-2 Nitrogen Tank Cart can be moved anywhere in the shop to service vehicles. Equipped with four (4) 25 foot hoses and quick lock air chucks, the NG-2 Nitrogen Tank Cart can service up to four (4) tires at one time and only requires each tire to be hooked up once.
