AC Hose Kit & HVAC Hoses – 3-Pack 72" Low Loss Refrigerant

The mytithger 3-Pack 72-Inch AC Hose Kit is designed for automotive technicians, HVAC specialists, and DIY mechanics servicing cooling systems. Connecting directly to standard manifold gauge sets, these hoses simplify charging, evacuation, and pressure diagnostics on vehicle air conditioners, residential mini-splits, and commercial equipment.

Each hose is fitted with an integrated compact ball valve that gives you immediate manual control over fluid flow. This setup allows you to stop refrigerant transfer instantly and minimize fluid loss or spray when disconnecting lines. Constructed from high-grade rubber with durable brass fittings and PTFE gaskets, the lines withstand working pressures up to 800 PSI, with a burst threshold of 4000 PSI, across an operating temperature range of -20°F to 180°F.

Color coding in standard red, yellow, and blue streamlines identification in busy work areas, helping you quickly distinguish high-side, low-side, and charging connections. The set offers wide refrigerant compatibility, working with R134A, R410A, R12, R1234yf, and A2L gases to bridge older legacy units and modern systems.

While the 1/4-inch SAE flare connections match standard ports, systems requiring different connection sizes will need separate adapters. Additionally, the generous 72-inch length provides great reach around large equipment, though managing excess hose slack in cramped engine bays requires extra care.

Verdict: This 3-piece hose set is a solid, versatile option for anyone needing dependable lines with integrated shut-off valves for manifold gauges. It is particularly well suited for technicians and handy homeowners working across diverse automotive and residential air conditioning setups.

• Hose Length: 72 inches
• Fitting Size: 1/4-inch SAE flare
• Working Pressure: 800 PSI
• Burst Pressure: 4000 PSI
• Operating Temperature Range: -20°F to 180°F
• Materials: High-grade rubber, brass fittings, PTFE gaskets
• Refrigerant Compatibility: R134A, R410A, R12, R1234yf, A2L
• Quantity: 3 hoses (Red, Yellow, Blue)

A great fit if you:

• Service a mix of modern and vintage AC systems, including R134A, R410A, and R12 units.
• Need the safety and efficiency of integrated ball valves to stop refrigerant loss.
• Require long 72-inch hoses to access hard-to-reach automotive or mini-split service ports.
• Use standard manifold gauges with 1/4-inch SAE connections.

Consider something else if you:

• Work exclusively in tight spaces where 72-inch lines create unnecessary clutter.
• Need fittings other than 1/4-inch SAE flare without using adapters.

What refrigerants are compatible with these hoses?
The hoses work with R134A, R410A, R12, R1234yf, and A2L refrigerants.

What are the pressure and temperature ratings?
They have an 800 PSI working pressure, a 4000 PSI burst pressure, and an operating temperature range of -20°F to 180°F.

What size fittings do these hoses have?
Each hose features 1/4-inch SAE flare brass fittings with PTFE gaskets.

How do the ball valves help during AC service?
The integrated ball valves allow you to shut off flow instantly, controlling charging and evacuation while reducing refrigerant loss upon disconnection.
