Descent Air Spool & Restrictor O-Ring Kit

Includes 4 - o-rings

1 - Std HP Spool O-ring (003) 
3 - Metric 1 x 3.3 (Unique to this transmitter)

The flow restrictor should be installed on a Descent transceiver which is attached directly to the high-pressure port on a regulator. (You will need two of the 1x3.3 orings) 

The air spool should be installed on a transmitter when attaching to a high-pressure hose.  (You will need one std HP Spool o-ring and 1x3.3 o-ring)

See the Garmin T2 quick start manual for more details. Compatible with T1 and T2.

Price includes shipping (typically need to order $250 for free shipping).  We throw these o-rings in an envelope and stick a stamp on it that's why the price is $6.78 and not just $6.
