Features & Benefits

Accuracy & Safety

• See it, trust it: the integrated sight glass lets you confirm the core is captured and refrigerant is flowing before removal.
• Deep-vacuum confidence: vacuum-rated to 20 microns for reliable evacuation and fewer callbacks.
• Secure core capture: a gasketed capture pin locks onto the core, reducing the risk of dropped or lost cores.
• A2L-ready: compatible with modern low-GWP refrigerants when used according to safe work procedures.

Durability & Worksite Readiness

• Built tough for Aussie sites: designed to handle heat, humidity, dust, and everyday knocks.
• High-pressure capable: 800 psi maximum working pressure supports demanding service tasks.

Ease of Use & Efficiency

• Comfort spinner cap: free-spinning, rubberised, magnetic cap improves grip and makes insertion/removal smoother against pressure.
• Mini-split friendly: quickly swap from 1/4″ to optional 5/16″ fittings for R410A/R32 systems.
• Faster jobs, fewer do-overs: positive core capture helps prevent rework and speeds up vacuum and charging.

FAQs

What is the reason for the Comfort Spinner on the capture rod of VC1G/VC2G?

The comfort spinner is a free-spinning, rubberised magnetic cap that improves grip and control, so you can insert or remove the core more easily under pressure while keeping the captured core secure and close at hand.

Does Fieldpiece offer repair kits for VCRTs?

Yes — Fieldpiece provides service parts like seals and O-rings so you can refresh a worn tool instead of replacing it. Reach out via our Fieldpiece collection and we’ll help you source the correct parts.

Are the VCRTs vacuum-rated?

Yes. The VC1G is vacuum-rated to 20 microns (≈0.027 mbar / 0.020 Torr), supporting reliable deep-vacuum performance.

How do I identify the 1/4″ versus the 5/16″ fittings?

1/4″ SAE flare is standard on most tools and service ports. 5/16″ SAE flare is common on many mini-splits (R410A/R32). If the 1/4″ won’t start cleanly on the port, you likely need the 5/16″ fitting. For adapters and fittings, see C&D valve fittings.

Are the 5/16″ fittings included with the VCRT?

No. The VC1G comes with a 1/4″ female service-port fitting as standard. The 5/16″ fitting is an optional accessory often used for mini-splits. Check availability in our Fieldpiece accessories.

What torque should I apply when swapping between 1/4″ and 5/16″ service-port fittings?

Seat the flare gently until snug and then tighten just enough to seal — do not over-torque. Always follow the VC1G user manual and your company’s procedures.

How should I store my VCRT?

Keep the tool clean and dry, replace worn O-rings/seals as needed, cap ports to keep dust out, and avoid leaving the tool pressurised or under vacuum between jobs. Store with your hose set or in a protected pouch.

What refrigerants are the Fieldpiece VCRTs compatible with?

The VC1G is compatible with today’s common refrigerants and is A2L compatible when used in line with safety practices and the manufacturer’s manual.
