XL4 ProSeal Inject Leak Sealant - 1.5 to 5 Ton - (Same as Easy Seal Direct Inject) - Uses the high side pressure or refrigerant cylinder pressure to inject the sealant into the low side with the system running in the cooling mode. - .1 oz super concentrated - Works with all refrigerants and oils. 1/4" SAE female hose fitting on one end and 1/4" SAE male hose fitting on the other end. Seals most leaks in residential/AC Cooling/Heat Pump Systems/Packaged Units/Mini Splits/Micro Channel Coils. Two or more injection tubes may be needed in commercial systems. Made by Envirosafe (ES-Refrigerants).

Please note: Female end of hose must be securely tightened to the unit (low side) to insure sealant is injected into the system. May be necessary to use pliers to insure proper connection. 

Simply Connect and Inject.

Enviro-Safe's ProSeal XL4 Inject is:

• Large equipment, bulky tools, injection hoses are a thing of the past

For Use In:

• heat pumps
• split systems & mini split units
• packaged units
• microchannel coils

• Description

  Pro Seal XL4 Inject is a new generation of sealants. Its patent pending injection method makes it easier to install than other sealants. With this new injection system, pumping down the unit is a thing of the past. EasySeal Direct Inject treats 1.5 to 5 ton systems.

  • Works with all refrigerants and oils.
  • Concentrated formula means less material in system.
  • Clear tube so you can see the sealant go in.
  • No need to pump down R-410A units.
  • Perfect for split systems, heat pumps, microchannel coils, packaged units, and mini splits.
  • No injection hose or caulk gun needed.
  • One time use.
  • • Make sure system is running and low side and high side service ports are properly identified. If unit is a heat pump, be sure it is in cooling mode. Connect Pro Seal XL4's Inject 1/4 ˝ SAE female fitting to the suction service port of system. The one way check valve will prevent back flow of refrigerant. Be careful not to allow refrigerant to spray on bare skin when connecting, as it could cause frostbite.
    • Make sure both valves on manifold gauge set are closed. Connect high side (red) line of manifold gauge set to the high side service port. Barely thread the middle manifold hose (yellow) to the 1/4 ˝ SAE male fitting of the Pro Seal XL4 Inject. Do not thread to the point of depressing the Schrader core. Briefly crack open high side manifold valve to purge air out of the yellow hose, close high side manifold valve, then quickly tighten yellow hose fitting to the injector.
    • Briefly open then close high side valve of the manifold gauge set to allow a little high side liquid to flow through the yellow hose and Pro Seal XL4 Inject tube. With high side valve of the manifold gauge set closed, wait one minute for the yellow hose and Pro Seal XL4 Inject to equalize to suction pressure. Disconnect Pro Seal XL4 Inject from suction service port and from manifold gauge set. Discard or recycle empty injector. Run system for 1 hour to allow product to fully circulate.

    NOTE: You may also use a refrigerant cylinder to push sealant into system while charging if the system is low on refrigerant. Just connect ProSeal XL4 Inject to service port and inject refrigerant through injector into system while charging.

    WARNING: Do not bend, cut or deform Pro Seal XL4 Inject tube. Be careful not to allow refrigerant to spray on bare skin, as it could cause frostbite.
