3 Pieces AC Manifold Gauge Hose Kit

Tigbear's 3-piece 5ft AC manifold gauge hose kit is a complete set of 1/4" SAE refrigerant hoses built for charging, vacuuming and pressure-testing R404A, R12 and R502 systems.

This kit combines three color-coded 60" hoses with iron-plated copper fittings and 1/4" SAE female flare threads, offering a robust, budget-friendly replacement or upgrade for HVAC service work. Designed for use with manifold gauges and charging rigs, the hoses support typical workshop pressures (maximum working pressure 500 PSI, burst rated to 2500 PSI) and include a 45° service port angle to improve access in tight engine bays and refrigeration cabinets.

How do these hoses perform during charging and vacuuming?

The Tigbear hoses are engineered to handle common refrigeration service tasks like pulling a vacuum and introducing refrigerant safely into a closed system. Their rubber construction and copper-plated fittings provide flexibility and leak-resistant connections for routine HVAC work.

• Five-foot length (60" / 152 cm) for reach without excess slack.
• Color coding: red (high), blue (low), yellow (charging) for fast, correct hookup.
• Working pressure 500 PSI, burst pressure 2500 PSI for typical service requirements.
• 45° angled service port simplifies access to hard-to-reach valves.

Are these hoses compatible with my refrigerant and gauge equipment?

Yes — the Tigbear kit is compatible with refrigerants R404A, R12 and R502 and fits standard 1/4" SAE female flare manifold gauge ports. They work well as replacements for many aftermarket manifold gauge sets and are suitable for both charging and pressure testing.

• 1/4" SAE female flare fittings match most HVAC manifold gauges and adapters.
• Specifically listed for R404A, R12, R502 refrigerants; also usable for similar systems within pressure limits.
• Good replacement for Master Cool-style setups and common shop manifolds.
• Not intended for systems exceeding 2500 PSI burst rating—observe system pressure limits.

What materials and construction make these hoses durable?

The hoses pair a flexible rubber inner body with iron-plated copper heads to resist corrosion and keep connections tight. That combination yields reliable service life for general HVAC tasks when handled normally and stored properly.

• Rubber hose body for flexibility and ease of routing around components.
• Iron-plated copper fittings for improved corrosion resistance and sealing.
• Crimped or swaged connections to resist separation under normal service loads.
• Angled port design reduces stress on fittings during tight installations.

How easy is it to use this set for DIY or professional work?

The Tigbear kit is straightforward: color-coded hookups and standard flare threads cut setup time and reduce errors for both pros and DIYers. Tasks like pulling a vacuum typically take about 15 minutes with proper pump equipment; charging follows standard manifold and scale procedures.

• Plug-and-play 1/4" SAE female flare fittings for quick connections.
• Color-coded hoses speed correct port selection during service.
• 45° angled ends improve ergonomics when valves are hard to reach.
• Five-foot length balances reach with manageable hose routing.

Who is this for? The Tigbear 3-piece 5FT AC manifold gauge hose kit is aimed at HVAC technicians, refrigeration specialists, fleet mechanics and competent DIYers who need a reliable, affordable set of replacement charging hoses. If you work on R404A, R12 or R502 systems and use standard 1/4" SAE manifold connections, this kit provides the length, fittings and convenience features—such as color coding and angled ports—that make routine charging, vacuuming and pressure testing faster and cleaner. Avoid using these hoses on systems that exceed recommended pressure ratings, and always follow safe refrigerant handling practices.
