Garmin Descent T1 and T2 Air Spool and Flow Restrictor Kit

This Air Spool and Flow Restrictor Kit is specially designed to work together with your Garmin Descent T1 and T2 Transmitters.  The Garmin Air spool is used when you need to connect the transmitter to a high pressure hose, while the flow restriction kit is used when you need to connect the Garmin T2 Transmitter directly to the High Pressure port of the regulator first stage.  These parts are important to keep for your Garmin T1 and T2 transmitter to work properly while ensuring accurate measurements.
