AURELIO TECH 4-Way A/C Manifold Gauge Set — 5ft Hoses, 3 Acme Adapters, Multi-Refrigerant

The AURELIO TECH Upgraded 4-Way A/C Manifold Gauge Set is a professional-grade refrigeration diagnostic kit built to read, charge and service R134A, R410A, R404A and R22 systems with long 5-foot hoses, three Acme tank adapters and adjustable couplers.

This upgraded manifold gauge set blends a four-valve manifold block with clearly marked analog gauges and heavy-duty fittings so HVAC technicians, mechanics and informed DIYers can inspect pressures, evacuate systems and add refrigerant across a wide range of refrigerants. It’s designed for faster, cleaner connections thanks to adjustable couplers and the included Acme tank adapters for common refrigerant cylinders. The kit balances portability with durability—suitable for truck toolboxes or a workshop cart.

How does this manifold gauge set make diagnosing A/C problems faster?

The four-valve design gives independent control of high, low and service ports so you can isolate lines, perform vacuum pulls and measure static and running pressures without swapping hoses. The large-diameter gauges feature readable scales for multiple refrigerants and snappy needle response for quick interpretation.

• Four-valve manifold for independent circuit control
• Dual-scale gauges calibrated for R134A, R410A, R404A and R22
• 5-foot color-coded hoses reduce reach issues and make truck work easier
• Adjustable couplers speed up leak-free connections

What fittings are included and why do they matter?

The kit includes three Acme tank adapters to match standard refrigerant cylinder valves and sturdy brass couplers to ensure a secure mechanical seal. These fittings minimize thread wear and let you switch cylinders quickly, cutting down on job time and reducing the chance of cross-threading or leaks.

• Three Acme tank adapters for common cylinder valve types
• Brass adjustable couplers for durable, leak-resistant connections
• Service-grade hose ends compatible with refrigeration ports

Can I use this set with different refrigerants safely?

This AURELIO TECH manifold is built to service multiple refrigerants—R134A, R410A, R404A and R22—because the gauges are marked with appropriate pressure-temperature scales. Always follow refrigerant-specific safety and recovery procedures and verify compatibility of seals and oils when switching between refrigerants.

• Gauges display pressure ranges for listed refrigerants
• Color-coded hoses help prevent cross-connection mistakes
• Use proper service practices and recovery equipment for each refrigerant

How durable and portable is this manifold gauge kit?

Built with a rugged aluminum manifold housing and brass fittings, the set is designed to withstand regular field use while staying lightweight enough for mobile technicians. The five-foot hoses balance reach and handling, and the compact layout fits easily into a service bag or toolbox.

• Aluminum manifold for corrosion resistance and low weight
• Brass couplers and Acme adapters for longevity
• Compact footprint for easy storage and transport

Who this is for: This AURELIO TECH 4-way manifold gauge set is aimed at HVAC professionals, automotive A/C technicians and experienced DIYers who work on refrigeration and air-conditioning systems using R134A, R410A, R404A or R22. If you need accurate analog readings, versatile cylinder compatibility and durable fittings in a portable package, this kit delivers the core tools required for pressure testing, evacuation and charging tasks while maintaining service-grade durability.
