The Ultimate Hi-Flow Core Removal Tool is a professional-grade,
vacuum and pressure-rated valve core removal accessory
designed for HVAC/R service, refrigerant recovery, and system
evacuation. By removing restrictive valve cores, it provides true
full-flow system access, significantly increasing both recovery
and evacuation speed as well as the achievable depth of
vacuum. It also allows connection to a vacuum gauge as close
as possible to the unit being evacuated. This tool will improve
service time on any system that relies on a Schrader valve for
refrigerant access.

Key Features & Benefits:

Full-flow valve core removal – Eliminates core restriction
for maximum flow, faster recovery/evacuation, and deeper
vacuum.
Deep-vacuum rated – Maintains leak-free performance under
vacuum conditions.
High-pressure rated – Safe for charging and use with high-
pressure refrigerants (e.g. R410A).
Magnetic base / secure handling – Prevents lost valve cores
during service.
Core-retention removal mechanism – Securely grips and
extracts cores to avoid loss.
Side-port connection – Enables gauges or hoses for
evacuation, charging, or testing.
No tools required - Hand tighten only.
Two sizes in one tool - 1/4” and 5/16”
Refrigerant Ready - Compatible with A1, HFC/HFO, low GWP
A2L and A3 refrigerants
