Arch Tube
To test the arch tube’s inflatable cell for leaks, inflate the arch tube orally until the cell becomes firm.
To inflate, flip the replaceable black dust cap off from the top of the red oral tube. Either blow air into
the oral tube (See Figure 2) until the arch tube is firm or first fill the arch tube halfway up with
compressed air at a low pressure (<10psig) and top off by blowing into the oral tube. Replace the dust
cap on top of the oral tube when you are done. Occasionally, dust particles get trapped in the oral
valve, causing it to leak slightly. Blowing into the valve and/or tapping on the valve with a finger will
usually clear the dust and stop the leak. Keep the dust cap in place at all times.
Allow the arch tube to sit overnight for 16 hours and then check to see if the inflatable cell is still firm.
A leaking arch tube will have become soft and should not be used.
Deflate once testing in complete. To deflate, remove the black dust cap from the top of the red oral
tube. Twist the dust cap around and insert small topside of the dust cap into the oral tube. Hold in
place to keep the valve open. At the same time squeeze the arch tube to force all the air out through
the oral valve until it is completely evacuated and flat.
Arch tubes are not repairable. Replace if necessary.
