CoreMax Access Valve & Tools

The Industry Standard for Efficient Processing of Packaged HVAC Refrigerant Systems.

The CoreMax Access Valve & Seat System provides up to five times greater processing flow than common Schrader® valves and has dramatically improved sealing performance. Plus, it provides easy and reliable system accessibility compared to stub tubes and leak prone "Saddle Valves".

CoreMax Tools are designed to work seamlessly with the CoreMax Access Valve in all processing stages (Evacuation, Charging, and Reclaiming. Together they form a flexible system that shortens processing times, while improving the quality of refrigeration products. 

Unlike other systems, this is an integrated system design that has been specifically designed to OPTIMIZE OEM PROCESSING, ELIMINATE ACCESS PORT LEAKS and MAKE FIELD SERVICING EASY!

Refrigerant Reclaim

CoreMax® SnapMate™ Service

Description:

CoreMax® SnapMate™ Service can be used to open the CoreMax Valve for reclaiming the refrigerant charge.

It can also be used to evacuate the system and to charge the system. 

An internal shut off valve stops flow when disconnected.  The ¼ flare (7/16-20 thread) allows for connection to standard refrigeration hoses.

System Evacuation

CoreMax® SnapMate™ Service

Description:

CoreMax SnapMate Service can be used to open the CoreMax Valve for evacuating the system in preparation for refrigerant charging.

It can also be used to reclaim the refrigerant inside the system prior to evacuation, and to charge the system.

An internal shut off valve stops flow when disconnected.  The ¼ flare (7/16-20 thread) allows for connection to standard refrigeration hoses.

CoreMax® Core Insertion Tool

Description:

An alternate tool is the CoreMax Core Insertion Tool. 

The CoreMax Core Insertion Tool will remove the CoreMax Valve from the CoreMax Seat and move it out of the flow path. This allows for significantly more rapid evacuation of the system than the CoreMax SnapMate Service.

When evacuation is complete use the tool to screw the CoreMax Valve into its Seat and torque to specification using a CoreMax Torque Tool.

Description:

The CoreMax Core Removal Tool is used to replace a CoreMax Valve WITHOUT the need to reclaim refrigerant or lose a charge.

  1. Simply connect the tool to the CoreMax Seat with the Ball & Sleeve latch.
  2. Push the Tee Handle forward and engage the hex of the CoreMax Valve (you will feel it drop into place).
  3. Turn counter-clockwise 5 turns and then pull/retract the Tee Handle all the way outward until it hits its stop.
  4. Close the ball valve handle.
  5. Unscrew the end cap that holds the Tee Handle.
  6. Remove the old Valve Core and insert a new one.
  7. Screw the cap back in place (make sure the o-ring is lubricated and not damaged).
  8. Open the ball valve and push the Tee Handle forward until the Valve touches its seat.  Then turn clockwise until the Valve is fully threaded into the Seat.
  9. Tighten the Valve to the proper torque of 8-10 Ft-lbs (0.90 – 1.1 N-m) using the CoreMax Torque Tool
