Aupoko Refrigerant Charging Hose Set — 3-piece color‑coded 7in hoses with brass ball valves, 1/4" SAE, 600 PSI

This kit includes three 7-inch hoses—red, blue and yellow—each fitted with solid brass manual shut-off ball valves and standard 1/4" SAE male and female fittings. Designed to be compatible with common refrigerants such as R134a, R410A, R22 and R12, the set is built for routine service tasks, leak checks and charging operations on air conditioning and refrigeration systems. The hoses are rated for high pressures and engineered for easy connection to gauges, manifolds and service ports.

How do these hoses fit my existing HVAC charging tools?

The hoses use standard 1/4" SAE threads on both male and female ends to mate directly with most diagnostic gauges, manifolds and service ports. The included brass valves screw onto the hose ends and give you a quick shut-off without extra adapters. This compatibility keeps connections simple during field service and reduces the number of separate fittings needed.

• Standard 1/4" SAE male and female thread connectors for widespread compatibility.
• Direct fit with common manifolds and gauge sets used in HVAC/R work.
• Brass valve integrates into the hose end — no separate adapter required.

Are these hoses durable and safe for high-pressure applications?

The hoses and valves are made from heavy-duty materials and designed to withstand demanding service conditions. The assembly features solid metal valve bodies and is pressure-rated to withstand bursts up to 3000 psi with a maximum recommended working pressure of 600 psi. That rating covers routine charging, recovery and pressure-testing tasks commonly encountered in maintenance work.

• Solid brass manual shut-off ball valves for long-term reliability.
• Pressure-tested construction: 3000 psi burst rating, 600 psi max working pressure.
• Robust metal fittings resist wear from repeated service use.

How does the ball valve design improve on traditional hose setups?

The quarter-turn ball valve gives quick, precise control of refrigerant flow and can be operated with a single hand, which is helpful when you’re juggling gauges, manifolds or service tools. Color-coded valve knobs (red, blue, yellow) let you instantly identify high-side, low-side and service lines. The valves screw securely onto the hose ends for leak-minimizing connections during charging or evacuating.

• Quarter-turn action for fast open/close control during service.
• Color-coded knobs for immediate line identification and reduced setup errors.
• Ergonomic valve lever designed for one-handed operation while working on systems.

Who is this for: This Aupoko hose set is aimed at HVAC technicians, refrigeration service professionals and experienced DIYers who need a compact, reliable charging solution. It’s ideal for routine charging, pressure checks and maintenance on residential and light commercial air conditioning and refrigeration equipment that uses common refrigerants. If you require heavy industrial lengths or specialized fittings, consider hoses tailored for those applications, but for everyday service work this kit delivers standardized connections, brass valve control and durable construction backed by a one-year warranty.
