Leaks, large or small, can lead to big problems. Some air conditioning and refrigeration system leaks are no wider than a human hair (300 µm). But even the smallest leaks let refrigerant and oil escape into the atmosphere. As a result:

  • The system must work harder, which uses more energy and shortens component life.
  • The loss of refrigerant increases friction, wear and risk of equipment damage.

A big advantage of ComStar's AC Zero Leak is that it contains no polymer; this means, no clogs, no worries. Because AC Zero Leak is polymer-free, offering a distinct advantage over many competitive formulations, it will NOT form hard particulate when it comes in contact with moisture in a system.  Polymer based products will cause this type of in system reactionthereby creating clogs or blockages.

ComStar's AC Zero Leak can be used in automotive, commercial and residential AC applications.  For commercial and residential A/C applications a 4 oz dosage (1 bottle) is good for up to a 12 ton system (2 oz or half bottle dosage for systems up to 6 ton).  For larger systems over 12 ton use appropriate ratio of approximately 1 oz per every 6 tons over the original 12 tons.  As an alternative way to estimate the dosage necessary, please refer to the product attachments that show dosage by the amount of refrigerant charge that a system holds.

Key Benefits

  • Specially formulated to stop small leaks in evaporators and condensers as well as around gaskets and seals
  • Designed not to harm AC systems
  • Non-hardening, polymer-free
  • Compatible with POE-based, PAG-based and mineral-oilbased mobile AC lubricants
  • Can also be used for preventive maintenance and left in an operating system

Technical Info

Refrigerant and Lubricant Compatibility

AC Zero Leak is formulated to be compatible with most refrigeration lubricants and leak stops. It can be added into virtually
any air conditioning system , including commercial and industrial air conditioning/refrigeration systems.

Container Types

AC Zero Leak can be exposed to the atmosphere for extended periods of time and still remain usable. This is
especially useful for professionals who may want to purchase the additive in bulk containers. Because of its stability,
this formulation also can be used with hand injection tools.

Treat Rates:

Refrigerant load Recommended dosage
< 1 kg (< 2.2 lb) 60 ml (2.0oz) (typical for most vehicles)
< 1.5 kg (< 3.3 lb) 90 ml (3.0 oz)
< 3 kg (< 6.6 lb) 180 ml (6.1 oz)
< 5 kg (< 11 lb) 300 ml (10.1 oz)

Instructions

  1. Start air conditioning/refrigeration system, and set cooling controls to coldest setting.
  2. Insert recommended dosage into oil injector.
  3. Connect oil injector to low-side service port.
  4. Recharge system with refrigerant (consult owner’s manual).

Application

By using AC Zero Leak you can:

  • Seal leaks safely, without damaging system components
  • Avoid the hassle and expense of replacing seals or other parts
  • Save energy
  • Prolong the life of system components
  • Stop corrosion from spreading

AC Zero Leak is ideal for a broad range of applications:

  • Automotive AC systems
  • Refrigeration systems
  • Residential Systems
