LIYYOO Refrigerant Charging Manifold Gauge Set for R410A R22 R404 — 60" 1/4" Hoses, Dual Recalibratable Gauges

LIYYOO Refrigerant Charging Hoses with Diagnostic Manifold Gauge Set is a complete HVAC charging and diagnostic kit for R410A, R22, and R404 systems, featuring 60" 1/4" hoses, dual gauges, quick couplers, and 5/16" SAE adapters.

This toolkit combines a heavy-duty aluminum manifold, recalibratable dual gauges, and three color-coded 60-inch hoses to streamline refrigerant charging, recovery checks, and basic diagnostics. Built with solid brass fittings, quick-disconnect couplers, and a visual sight glass, the set is designed to give technicians and DIYers reliable access and clear readings when servicing split systems, car A/C, or light commercial refrigeration.

How accurate and durable are the LIYYOO gauges and hoses?

The manifold uses robust aluminum construction with dual gauges that can be recalibrated in the field to maintain measurement accuracy over time. Hoses are built for long service life with reinforced fittings and high burst pressure ratings to minimize downtime and safety risks.

• Recalibratable dual gauges for sustained accuracy.
• Hoses rated 800 PSI working, 4000 PSI burst pressure.
• Solid brass connections for corrosion resistance and secure seals.
• Durable aluminum manifold body with heavy-duty hanging hook.

Which refrigerants and fittings does this set support?

This set is configured for mainstream refrigerants including R410A, R22, and R404 with standard 1/4" female flare fittings and two supplied 5/16" SAE adapters for R410A systems. A 45° angled service port end and valve-core depressor simplify hookups to service valves in tight or awkward positions.

• Compatible with R410A, R22, R404 refrigerants.
• Standard 1/4" female flare hose ends and 5/16" SAE adapters included.
• 45° angled port for easier access to service valves.
• Quick-disconnect couplers for high and low side connections.

What features improve on-the-job convenience and safety?

The manifold includes an extra-large sight glass to monitor liquid flow and a heavy-duty hook to keep the unit accessible while you work. Quick couplers and secure brass fittings reduce the chance of leaks, while the long 60" hoses extend reach for safer positioning around equipment.

• Extra-large sight glass for visual refrigerant observation.
• Heavy-duty hanging hook for hands-free operation.
• Quick disconnect couplers to speed up hookups and reduce leaks.
• 60" hose length for better reach and maneuverability.

How do I maintain or recalibrate the gauges?

The dual gauges are designed for field recalibration to keep readings reliable; follow the manufacturer calibration steps or send the gauges to a shop for precision adjustment. Regular checks for loose fittings, hose wear, and sight-glass clarity will extend the kit's useful life and ensure safer service procedures.

• Gauges are user-recalibratable; follow enclosed instructions for field adjustment.
• Inspect hoses and fittings before each use for wear or leaks.
• Keep sight glass clean to monitor refrigerant condition effectively.
• Replace O-rings and adapters as recommended to maintain sealing integrity.

Who is this for: The LIYYOO Refrigerant Charging Hoses and Diagnostic Manifold Gauge Set is intended for HVAC technicians, automotive A/C specialists, and confident DIYers who service refrigeration or air conditioning systems using R410A, R22, or R404. It suits users who need long-reach hoses, dependable brass fittings, visual flow confirmation, and the ability to recalibrate gauges for continued on-the-job accuracy.
