VC1G is a tool for removing and installing service valve cores in HVAC/R systems. The built-in sight glass helps confirm the core is gripped before closing the ball valve and withdrawing the piston assembly. What it's used for Removing and installing service valve cores in HVAC/R installations Visual confirmation of valve core engagement through the built-in sight glass Service work where removing the core improves flow during evacuation or system handling Servicing air conditioners, heat pumps, and refrigeration equipment with 1/4″ or 5/16″ ports Field work where better control at the service port is needed Key features Built-in sight glass — allows visual confirmation that the valve core is gripped before disconnecting the tool Valve core gripper — holds the core during removal and installation, reducing the risk of losing it Ball valve — isolates the service port after the core is removed Comfort spinner handle — makes turning the spindle easier during repetitive service work 1/4″ and 5/16″ connections — works with standard service ports and mini-splits Deep vacuum rated — rated to 20 microns per source data A2L compatibility — tool materials are rated for modern A2L refrigerant service applications Selected specifications Type Valve core removal tool / VCRT with sight glass Model Fieldpiece VC1G Service connections 1/4″ and 5/16″ Vacuum rating 20 microns / 0.027 mbar / 0.020 Torr Maximum working pressure 800 psi / 55 bar Approximate dimensions 13 cm × 6 cm Approximate weight 322 g Refrigerant compatibility A2L per Fieldpiece / product listing data In the box Fieldpiece VC1G valve core removal tool with sight glass Replacement 1/4″ and 5/16″ service connections Manufacturer documentation
