Used to reduce high pressure through a series of tee and flexible pigtail connectors, our exclusive Low Pressure Airline Cascade Kits offer you the ease of ordering all the parts you need for your system with one part number. No more forgetting a piece or mis-matched fittings. Inline check valves on both the tee and flexible pigtail (available in both high and low pressure) are used to allow for uninterrupted air flow while replacing depleted cylinders. An optional low-on-air warning device alerts the user when air is low. Individual components are available for adding on to an existing system, or for building a high pressure cascade system.
