FasTest HVAC-R OEM Ports

FasTest HVAC service ports and refrigeration access valves deliver superior quick-connect solutions for charging, evacuation, leak testing, and processing in modern HVAC-R systems. Replace outdated Schrader valves or stub tubes with our service port hvac designs—like CoreMax, ZeroMax, and PortMax—for up to 5x higher flow rates, near-zero emissions, and hermetic sealing that complies with low-GWP refrigerants. These service port refrigeration innovations reduce processing time, minimize refrigerant loss, and enhance safety for OEM manufacturers and field service alike.

Faster Processing of Systems Using Schrader Type Valves

View

The CoreMax® access valve system provides up to five times greater processing flow than common Schrader® valves and the integral shut off valve has dramatically improved sealing performance. The 1/4 flare profile is compatible with standard processing and service tools.
 

Applications:

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

Anywhere a Schrader® valve is used.

Easy Access for Small Systems using Processing "Stub" Tubes

View

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.

Applications:

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

Anywhere a Process Stub Tube is used.

Rapid Evacuation of Large Capacity Systems

View

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.

 

Applications:

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

Anywhere Packed Angle/Ball Valves are used.

Why Choose FasTest HVAC Service Ports & Refrigeration Access Valves?

  • Maximum Flow & Speed — CoreMax provides up to 5x greater processing flow than standard Schrader valves; PortMax slashes evacuation times for large-volume systems—ideal for faster production cycles and reduced takt time.

  • Near-Zero Emissions & Sustainability — ZeroMax eliminates stub tubes with hermetic metal-to-metal sealing for near zero emission charging/evacuation; fully compatible with 21st-century low-GWP refrigerants to meet environmental regulations.

  • Safer, More Reliable Access — Integral shut-off features and quick-connect designs minimize leaks, refrigerant loss, and operator exposure—enhancing hvac service port reliability during manufacturing, field service, or recovery.

  • Versatile Applications — From residential packaged units and mini-splits to commercial refrigeration, ice makers, and PTAC systems—our refrigeration access valves replace traditional methods across the HVAC-R industry.

  • Custom & ICON-Ready Options — Need a tailored service port hvac solution? We either have it or can make it, with optional ICON™ Technology for smart verification, data logging, and automation integration.

Key Applications for FasTest Access Ports

  • Residential and commercial air conditioning units (packaged, ducted split, mini-splits)

  • Refrigeration systems (display cases, food merchandisers, cold chain equipment)

  • PTAC/VTAC, ice makers, pool heat pumps, and large chillers

  • OEM production lines requiring high-throughput charging/evacuation/leak testing
