1.5m Refrigeration Charging Hose Set for HVAC Manifolds

Reliable charging hoses for accurate HVAC service work.

This 1.5 m refrigeration charging hose set is designed for professional servicing of air conditioning and refrigeration systems using common refrigerants, including R134a, R410a, R22, R12 and R502. Constructed from durable rubber with metal reinforcements, each hose is built to handle demanding field conditions and frequent use in workshop or on-site environments.

The set includes three color-coded hoses - red (high pressure), blue (low pressure) and yellow (refrigerant/charging) - for clear, error-free identification during connection. Each hose is fitted with 1/4" SAE female brass fittings, providing secure, leak-resistant joints to manifold gauges and service ports. With a working pressure rating of 800 PSI and a burst pressure of 4000 PSI, these hoses offer a safe operating range for standard HVAC diagnostic and charging procedures.

Engineered for compatibility with manifold gauge sets such as the Testo 550, the hoses deliver consistent pressure transfer for accurate readings and controlled refrigerant flow. Their flexible construction helps technicians work efficiently in tight spaces while maintaining reliable sealing performance over time.

Why It's a Smart Choice

• Wide refrigerant compatibility - Suitable for R134a, R410a, R22, R12 and R502, supporting a broad range of service tasks with a single hose set.
• Professional pressure ratings - 800 PSI working and 4000 PSI burst pressure help maintain safety and reliability during charging and evacuation.
• Clear, organized workflow - Color-coded hoses and 1/4" SAE brass fittings simplify setup, reduce connection errors and support consistent, repeatable results.

FAQ

Q: What manifold gauges are these hoses compatible with?
A: The hoses use standard 1/4" SAE female fittings, making them compatible with most common manifold gauge sets, including the Testo 550 and similar HVAC service manifolds.

Q: Can these hoses be used with R410a systems?
A: Yes. They are rated to 800 PSI working pressure and 4000 PSI burst pressure and are suitable for use with R410a as well as R134a, R22, R12 and R502.

Q: What is the length of each hose?
A: Each hose in the set is approximately 1.5 meters (about 5 feet) long, providing a practical balance between reach and manageability.

Q: Are shut-off valves included on the hose ends?
A: The hoses are supplied with 1/4" SAE female brass fittings. If your application requires specific shut-off or ball valves, please verify compatibility with your existing adapters or manifold set.
