Vapco’s Direct Inject Gun is the easiest, quickest, most innovated method for injecting air conditioning and refrigeration leak sealers, dyes and system enhancers into a system.  This CO2 gun can be used with Vapco’s full line of direct inject products.


To use the Xpress Seal Direct Inject Gun:


Turn the A/C system on and verify the unit is running.  With the CO2 cartridge in the gun, connect the Xpress Seal product to the Direct Inject Gun.  Connect the other end to the low-side service port.  Briefly pull the trigger.  The direct Inject Gun will meter just enough CO2 to empty tube.  The Xpress Seal product has now been injected into the system.  Disconnect the empty tube from the low-side port.  Install service port cap.  Run the A/C unit at least one hour after installing a Vapco Xpress Seal product.

Perfect for split system, heat pumps, microchannel coils, packaged units, and mini splits..
