Tigbear AC Manifold Gauge Hose Kit 60in 3-hose (Red/Blue/Yellow) 1/4in SAE, 500 PSI

The Tigbear AC Manifold Gauge Hose Kit is a three-hose, 5-foot refrigerant charging set built with 1/4" SAE female flare fittings for servicing R404A, R12 and R502 HVAC systems.

This three-piece Tigbear hose kit gives technicians and DIYers a straightforward way to charge, test and evacuate small refrigeration and air-conditioning systems. Each hose measures 60" (152 cm) and uses color-coded rubber lines—red for high, blue for low and yellow for service/charging—terminated with iron-plated copper heads for corrosion resistance and reliable sealing. The assembly is engineered for a maximum working pressure of 500 PSI and a burst threshold up to 2500 PSI, making it suitable for many light to medium duty applications when used within those limits.

How does the Tigbear kit fit into a typical charging or evacuation workflow?

You connect the color-coded hoses between your manifold gauge and the system service ports and vacuum pump or refrigerant cylinder. The yellow service hose handles charging and recovery, while the red and blue hoses monitor high and low side pressures so you can balance and diagnose the system.

• 60" hose length for flexible reach to service ports
• 1/4" SAE female flare threads for standard manifold and valve compatibility
• Color coding (red/blue/yellow) to prevent connection errors
• Iron-plated copper fittings for better seal and corrosion resistance

Which refrigerants and pressure limits are supported by these hoses?

The hoses are specified for R404A, R12 and R502 service; they are also usable on R22/R12/R502 systems when users stay under the stated burst rating. Do not exceed the kit's pressure limits: a normal maximum working pressure of 500 PSI and a tested burst capacity of 2500 PSI.

• Compatible refrigerants: R404A, R12, R502 (also usable on R22 in applicable situations)
• Maximum working pressure: 500 PSI
• Burst pressure: 2500 PSI — do not exceed
• Hose length: 60" / 152 cm for each line

What construction features help with durability and ease-of-use?

The Tigbear hoses combine a flexible rubber exterior with iron-plated copper heads to resist wear and help keep fittings tight. Service ports are set at a 45-degree angle for easier attachment in cramped engine bays or rooftop units, and the 1/4" SAE female flare thread is a standard fit for most manifold gauges and service valves.

• Rubber hose body designed for flexibility and abrasion resistance
• Iron-plated copper heads for improved sealing and corrosion protection
• 45° angled service-port ends for easier access in tight spaces
• Standard 1/4" SAE female flare threads for broad compatibility

How simple is this set for DIYers and first-time users?

The kit is intended to be user-friendly: color-coded lines and standard fittings reduce mistakes, and the hoses are long enough to reach most service points without stretching. Typical procedures like pulling a vacuum before charging can be completed quickly when paired with a proper manifold and vacuum pump.

• Color-coded hoses to minimize hookup errors
• 60" length lets you position gauges and pumps away from the service port
• Ready replacement for worn or damaged hoses on many gauge sets
• Suitable for vacuuming, pressure testing and charging of compatible systems

Who this is for: The Tigbear AC Manifold Gauge Hose Kit is aimed at HVAC technicians, refrigeration service professionals and competent DIY enthusiasts who work on small to medium refrigeration or AC projects using R404A, R12 or R502. It suits anyone needing a dependable, standard-sized replacement hose set with corrosion-resistant fittings and easy access ports; it is not intended for systems or procedures that exceed the hose pressure ratings or require specialized refrigerant-specific certification.
