Tigbear R134A AC Charging Hose Kit 5ft (60in) 3‑Color Set — 1/2" ACME, 600 PSI, Brass Fittings

Tigbear R134A 5-foot manifold gauge hose kit is a three‑hose charging and testing set built from brass fittings and reinforced rubber for safe R134A refrigerant service up to 600 PSI.

Designed as a reliable replacement or spare for HVAC technicians and DIYers working on vehicle or small-system air conditioning, this 60‑inch, 3‑colored hose kit includes high‑ and low‑pressure lines plus a center charging hose with a quarter‑turn shut‑off valve. The hoses use 1/2" ACME female threads and 14mm male connections where specified, with durable construction to handle routine pressure tests, vacuum pulls, and refrigerant charging for R134A systems.

How does this hose kit fit my R134A AC service setup?

The Tigbear kit is configured for standard R134A service ports and replaces many common aftermarket hoses. The red and blue hoses connect to high and low ports respectively, while the yellow center charging hose attaches to refrigerant cans, recovery machines, or vacuum pumps using 1/2" ACME female fittings.

• 3 hoses: red (high), blue (low), yellow (charge/test)
• 1/2" ACME female fittings for industry compatibility
• 60" length gives flexible reach around engine bays and components
• Designed specifically for R134A refrigerant systems

What pressure limits and safety features does it offer?

Each hose is built to a working pressure of 600 PSI with a 3000 PSI burst rating, sufficient for standard diagnostic and charging tasks on R134A systems. Brass fittings reduce corrosion risk and reinforced rubber resists kinks and wear for dependable, long‑term service.

• Maximum working pressure: 600 PSI
• Burst pressure: 3000 PSI for added safety margin
• Brass connectors for secure, leak‑resistant connections
• Reinforced rubber hose for durability and flexibility

How does the shut‑off valve on the yellow hose improve control?

The yellow center charging hose includes a quarter‑turn shut‑off valve that lets you start or stop refrigerant flow quickly without disconnecting fittings. That valve is useful for controlled charging, isolating the charge line during pressure tests, or preventing drips when swapping tools or cans.

• Quarter‑turn valve for immediate on/off control
• 1/2" ACME female x 1/2" ACME female threading for common connections
• Helps maintain system vacuum and prevents unwanted leaks
• Simplifies switching between charging and testing equipment

What maintenance and typical uses should I expect?

These hoses are designed for routine HVAC work such as vacuuming line sets, measuring pressures, and charging R134A refrigerant. Regular inspection of O‑rings and fittings, avoiding sharp bends, and storing hoses away from prolonged sunlight will extend service life.

• Use for pressure testing, vacuum pulling, and refrigerant charging
• Inspect fittings and O‑rings before each use
• Avoid extreme twisting or pinching to preserve hose integrity
• Store indoors to prevent UV and ozone degradation

Who is this for? This Tigbear R134A manifold hose kit suits professional HVAC technicians, mobile mechanics, and knowledgeable DIYers who work with vehicle or small commercial R134A air conditioning systems. It’s a practical replacement or backup set for anyone needing reliable, service‑grade hoses with industry‑standard fittings, straightforward shut‑off control, and robust pressure ratings for everyday diagnostic and charging tasks.
