Wadoy AC Refrigerant Recharge Hose Kit 59" — Low-Side Gauge, Brass Fittings for R410A/R134A/R22

The Wadoy 59" AC Refrigerant Recharge Hose Kit is a complete low-side charging assembly with a clear pressure gauge and adapters for R410A, R134A and R22 systems.

This compact recharge kit combines a 59-inch reinforced hose, a low-side pressure gauge with control valve, and common SAE adapters so you can connect to residential or automotive air conditioners quickly. Designed for routine charging and diagnostic tasks, the kit pairs durable brass fittings with a multi-scale dial so users can observe pressure during service and top up compatible refrigerants safely when following proper procedures.

How do I set up the Wadoy kit for a basic AC recharge?

Setup is straightforward: attach the appropriate adapter to the service port, connect the hose to the refrigerant canister and then to the gauge valve. Open the low-side valve slowly and watch the gauge for steady readings while charging. Close the valve and remove fittings when complete, following standard safety and environmental practices for refrigerant handling.

• Select the correct adapter (R410A or R134A/R22) for the system service port.
• Secure brass fittings to avoid leaks and use the control valve to regulate flow.
• Monitor pressure on the color-coded dial while adding refrigerant incrementally.
• Shut the valve and purge hose before disconnecting to reduce refrigerant loss.

What measurements and pressures does the gauge show?

The included gauge is a low-side diagnostic instrument with multi-scale markings, providing clear, color-coded readings for typical refrigerant pressure ranges. It helps you track the system’s low-side pressure during charging and basic troubleshooting. While excellent for general monitoring, it is not a substitute for full manifold sets when performing advanced diagnostics.

• Large dial with multi-scale, color-coded pressure ranges for quick interpretation.
• Designed specifically for low-side monitoring during refrigerant addition.
• Brass valve allows controlled charging and stable pressure display.

Which refrigerants and systems are compatible with this hose kit?

This Wadoy recharge assembly supports common refrigerants including R410A, R134A, R22 and R404A, making it suitable for many residential mini-splits, home AC units and automotive systems that use those refrigerants. Adapters included cover standard SAE fittings so you can reach common service ports without aftermarket fittings. For systems using alternative refrigerants or for recovery work, consult manufacturer guidance and local regulations.

• Includes adapters for R410A (1/4" SAE to 5/16" SAE) and R134A tank adapter (1/4" SAE to 1/2" SAE).
• Works with mini-split units, home ACs and many vehicle air conditioners using compatible refrigerants.
• Not intended for refrigerant recovery or high-side measurement without appropriate tools.

How durable and safe are the hose and fittings for repeated use?

The hoses are made from reinforced rubber and paired with solid brass connectors to resist corrosion and provide secure sealing under normal HVAC working pressures. The kit carries a high burst threshold compared to its working pressure, offering a margin of safety for routine service work. Always inspect hoses and fittings before each use and follow safe handling practices for pressurized refrigerants.

• Reinforced rubber hose for flexibility and long-term use.
• Heavy-duty brass fittings for corrosion resistance and tight seals.
• Rated working pressure suitable for standard low-side charging tasks.

Who this is for: The Wadoy 59" Refrigerant Recharge Hose Kit is aimed at DIY homeowners, small HVAC contractors, and vehicle owners who perform routine AC topping and low-side diagnostics. It’s ideal for users who need a portable, easy-to-connect charging solution that covers common refrigerants and service ports, provided they follow refrigerant handling rules and are comfortable performing basic AC maintenance.
