The Kleinn Model 6450RT is a heavy-duty, 5-gallon steel replacement air tank engineered as the ultimate high-capacity reservoir for the 6450 onboard air system, the ProBlaster HK9 train horn kit, and demanding custom pneumatic setups. Built to handle maximum volume and high-pressure performance, this rugged tank features an advanced seven-port layout—including six 1/4" NPT ports and one high-flow 1/2" NPT port—allowing for exceptionally clean plumbing, effortless accessory routing for air tools or suspension bags, and a guaranteed moisture drain point regardless of how it is positioned on your vehicle's chassis.
