  • Residential Packaged Units
  • Small Commercial Packaged Units
  • Commercial Ice Makers
  • Food Merchandizing Cases
  • Swimming Pool Heat Pumps

Anywhere a Schrader® valve is used.

Zero Emission Split System Processing

  • Unitary AC Packages & Heat Pumps
  • Self-Contained Display Cases
  • Refrigerated Air Handler/Condensing Units
  • Commercial Ice Makers
  • Pool Heat Pumps

Anywhere a Restrictive & Leak Prone Schrader Valve is Used.



Easy Access for Small Systems using Processing "Stub" Tubes


The NEW ZeroMax™ access port system is specifically designed to eliminate the need for Process “Stub” Tubes, while adding easy access without sacrificing hermetic metal-to-metal sealing. ZeroMax™ has the capability for near zero emission processing and field servicing, and is compatible with both current and next generation refrigerants.


  • PTAC/VTAC Units
  • Ducted Split Systems
  • Commercial Display Units
  • Refrigerators
  • Mini-Splits

Anywhere a Process Stub Tube is used.

The NEW PortMax™ access port system is specifically designed to reduce processing time, in particular, evacuation time (degass/dehydrate) of large volume refrigerant systems currently processing through packed angle or ball valves.


  • Industrial Refrigeration
  • Commercial Refrigeration
  • Air & Water Cooled Chillers
  • Cold Chain
  • VRV/VRF Plumbing
  • Air Handlers

Anywhere Packed Angle/Ball Valves are used.
