Aupoko 1/4" SAE Low-Loss Ball Valve Set (3-Pack) — Brass Shut-Off Valves with 45° Service Port and Knurled Nuts

These three Aupoko 1/4" SAE ball valves are built for charging, recovery, and service work with common refrigerants such as R134a, R410A, R22 and R12. Each valve screws directly onto a charging hose and features a color-coded, one-hand quarter-turn handle and a 45° angled service port to simplify access in tight equipment bays. Constructed from brass alloy with knurled coupler nuts and a green rubber gasket, the set provides reliable sealing at refrigerant pressures encountered in professional and DIY environments.

How does the Aupoko ball valve make refrigerant charging and recovery easier?

The valve gives technicians quick, single-handed control to open or stop refrigerant flow without disconnecting hoses, minimizing loss and contamination. The 45° service port improves access to service valves in cramped locations, and the knurled coupling lets you finger-tighten securely for fast swaps.

• One-hand quarter-turn handle for instant shut-off.
• 45° angled service port for easier access in tight spaces.
• Knurled nuts enable quick finger-tight connections.
• Green rubber gasket reduces leakage risk during service.

What refrigerants and systems are these valves compatible with?

Designed as universal low-loss fittings, the valves work with standard HVAC and automotive refrigerants including R134a, R410A, R22 and R12. They connect to 1/4" SAE male/female hose fittings used on charging hoses, manifolds and recovery lines, making them useful on residential, commercial and vehicle A/C systems.

• Compatible with R134a, R410A, R22, R12 refrigerants.
• Fits 1/4" SAE charging hose male and female fittings.
• Suitable for HVAC systems, service manifolds, and auto A/C.
• Works for both charging and recovery operations.

How durable and safe are these Aupoko shut-off valves?

Manufactured from high-quality brass alloy, the valves resist corrosion and stand up to repeated field use. Rated to a maximum working pressure of 800 psi (55 bar) and a burst pressure around 4000 psi (276 bar), they offer a strong safety margin for typical charging and recovery tasks.

• High-strength brass alloy construction for long service life.
• 800 psi (55 bar) maximum working pressure specification.
• Approximately 4000 psi (276 bar) minimum burst pressure safety margin.
• Color-coded handles (red/yellow/blue) for quick identification.

How do I install and operate the Aupoko low-loss ball valve?

Screw the valve onto the 1/4" SAE charging hose end and hand-tighten the knurled coupler nut until snug; no special tools are required for initial assembly. Operate the quarter-turn handle to open or close flow; use the angled service port to connect gauges or lines without removing the valve, reducing refrigerant loss.

• Thread onto 1/4" SAE hose ends and hand-tighten coupler nuts.
• Use quarter-turn handle to start/stop refrigerant flow quickly.
• Attach gauges or lines to the 45° service port for low-loss service.
• Pack includes three valves for multi-line setups or spare parts.

Who this is for: HVAC technicians, mobile A/C mechanics, and knowledgeable DIYers who perform refrigerant charging or recovery will appreciate the time-saving control and leak-resistant connections this Aupoko valve set offers. If you need compact, durable shut-off valves that integrate with standard 1/4" SAE hoses for residential, commercial, or automotive refrigerant servicing, this three-piece set supplies a practical, cost-effective upgrade to your toolkit.
