EZ Chill Auto AC Recharge & Seal vs InterDynamics EZChill R-134a Recharge Kit

Both are R-134a recharge kits with leak sealer, so the real difference is what comes in the can and the gauge. The InterDynamics EZChill kit adds a lubricant, which helps a system that has lost oil along with refrigerant. The EZ Chill kit is the better pick if you want a reusable in-line gauge and a push-button dispenser for topping off over months. Owners of both report the sealer slows small leaks but does not fix a failed component, and neither kit works on newer R-1234yf systems.

• Choose the EZ Chill kit if you want a reusable gauge and push-button dispensing for a slow leak you top off yourself.
• Choose the InterDynamics EZChill kit if you want refrigerant plus lubricant in one can for a system that has been low a long time.
