Orion Motor Tech 4-Way AC Manifold Gauge Set for R1234yf/R134a — 5ft Color-Coded Hoses, Aluminum Body

The Orion Motor Tech OMT 4-way AC manifold gauge set is a complete HVAC charging and diagnostic kit designed to service R1234yf, R134a and R404a systems with durable aluminum construction and color-coded 5ft hoses.

This professional-grade manifold pack brings precise pressure reading, safe refrigerant handling, and multi-fluorinated-gas compatibility into a single toolbox-ready unit. Built for technicians and knowledgeable DIYers, the kit pairs oil-filled and dry-core gauges with quick couplers and self-sealing can taps so you can check, evacuate, and refill A/C systems efficiently. Reinforced hoses, solid copper fittings, and calibration adjustments are included to support repeated field use and clear diagnostics across common automotive and light commercial refrigerants.

How does this manifold gauge set help diagnose A/C pressure quickly?

The included high- and low-pressure gauges give immediate, readable pressure values so you can determine system status and spot leaks or blockages. The oil-filled core on one gauge reduces mechanical shock and the dry dial enhances low-temperature readability during winter servicing.

• High/low gauges with calibration screws for ±1.6% accuracy
• Oil-filled core for shock resistance and longer life
• Dry dial for better cold-weather performance
• Clear, color-coded ports for fast hookup

What fittings and adapters are included, and why do they matter?

This bundle arrives ready to work: quick couplers, self-sealing can taps for both R1234yf and R134a, plus 1/4" male to 1/2" female adapters in left- and right-hand threads. Those components let you attach to different service valves and charging sources safely without improvised connectors.

• Two quick couplers for R1234yf and two for R134a
• Self-sealing can taps for both refrigerants to limit leakage
• Left- and right-hand threaded adapters for wide valve compatibility
• Aluminum body and pure copper fittings to resist corrosion

Are the hoses durable enough for professional use?

Yes — the kit uses 5ft, color-coded PVC hoses constructed with four reinforcement layers to handle demanding shop environments and high working pressures. The hoses are rated for operational use up to 800 psi and have a much higher burst threshold for safety margin under stress.

• Five-foot length balances reach and control at the manifold
• Four-layer reinforced PVC for abrasion and pressure resistance
• Working pressure rated to 800 psi; burst pressure significantly higher
• Color coding speeds identification and reduces hookup errors

Can this set be used with modern R1234yf systems and older refrigerants?

The OMT manifold is configured to service R1234yf, R134a and R404a, making it versatile across newer automotive A/C systems and legacy equipment. Included can taps and couplers match the specific connections required by each refrigerant, minimizing cross-contamination when used correctly.

• Designed for R1234yf, R134a, and R404a compatibility
• Separate couplers and taps for different refrigerants reduce mixing risk
• Suitable for pressure measurement, evacuation, and recharge tasks
• Use with appropriate refrigerant handling procedures and PPE

Who is this for: The Orion Motor Tech OMT 4-way manifold gauge set is aimed at trained automotive technicians, HVAC professionals, and experienced DIYers who service vehicle and light commercial A/C systems. It suits users who need a rugged, accurate kit that handles multiple refrigerants, offers clear diagnostics, and includes field-ready fittings and reinforced hoses. This set is not a substitute for certified refrigerant recovery equipment or formal HVAC training; follow local regulations and safety practices when working with refrigerants.
