Refrigeration charging hoses are flexible, durable tubes used by HVAC technicians to charge or evacuate refrigerant from air conditioning systems. They are typically color-coded and built to withstand high pressure.
Specification :
-
- Durable Material: Hoses are typically made of high-quality rubber, reinforced with nylon braiding for strength and durability.
- High-Pressure Rating: They are designed to work with high pressures (commonly 600-800 PSI working pressure and 3000-4000 PSI burst pressure) to ensure safe operation.
- Color-Coded: Hoses generally come in a set of three colors for easy identification during use:
- Red: for the high-pressure side of the system.
- Blue: for the low-pressure side.
- Yellow: for the central port, connecting to the refrigerant source or vacuum pump.
- Fittings: Most hoses feature 1/4″ SAE female fittings on each end, with some having a 45-degree angle on the service port side for easier access.
- Compatibility: They are designed to work with various refrigerants (e.g., R-134a, R-410A, R-22) but it’s crucial to confirm compatibility for specific refrigerants.
- Additional Features: Some hoses come with advanced features like integrated ball valves for flow control or SealRight™ fittings to minimize refrigerant loss.
