Directions

Directions Using Vapco’s Direct Inject Gun:

Turn the A/C system on and verify the unit is running. 

  1. With the CO2 cartridge in the gun, connect the Xpress Seal to the Direct Inject Gun. 
  2. Connect the other end to the low-side service port.  Briefly pull the trigger. 
  3. The direct Inject Gun will meter just enough CO2 to empty tube. 
  4. The sealer has now been injected into the system. 
  5. Disconnect the empty tube from the low-side port.  Install service port cap. 
  6. Run the A/C unit at least one hour after installing Xpress Seal. 

12+ uses per CO2 cartridge.


For traditional methods using refrigerants to install Xpress Seal use the following instructions:

  1. Turn the a/c system on and verify the unit is running. 
  2. Connect Xpress Seal to the low-side service port of the system.  (This is generally the large line).
  3. Connect the manifold refrigerant hose to the refrigerant supply tank. 
  4. Verify the high and low side valves on the manifold are closed before proceeding. 
  5. Purge the low pressure hose when connecting to Xpress Seal.
  6. Open low-side valve and watch for the tube to clear.  (This will ONLY take a few seconds!) 
  7. Turn off low-side manifold valve as soon as the tube is clear. 
  8. Turn off refrigerant gas.  Verify the system is charged to manufacturer’s specifications! 
  9. Disconnect low-side hose from Xpress Seal.
  10. Remove Inject.
  11. Install service port cap. 
  12. Run the a/c unit at least one hour after installing Xpress Seal.  (Do not bend or kink hose!)
