Orion Motor Tech AC Manifold Gauge Set — 4-Way with 5 ft Hoses for R1234yf/R134a, Aluminum, Oil-Filled Gauges

The Orion Motor Tech OMT 4-way AC manifold gauge set is a professional-grade HVAC tool engineered to read, evacuate and refill R1234yf, R404a, and R134a systems with durable aluminum construction, precision oil-filled gauges, and four reinforced 5 ft color-coded hoses.

This complete manifold kit brings professional features to garages, workshops, and mobile technicians. It pairs high-accuracy pressure gauges and calibration screws with sturdy fittings and quick couplers for both R1234yf and R134a, so you can service a wide range of light-duty automotive and small HVAC systems without swapping toolsets. The set is designed for reliable field use, resisting shock and corrosion while providing the connections and adapters needed to start work immediately.

How accurate and durable are the gauges for regular service work?

The kit uses oil-filled cores for the high and low pressure gauges to dampen needle movement and resist wear, while dry dials improve low-temperature performance. Calibration screws let you fine-tune readings, with factory accuracy within approximately 1.6%, helping you trust diagnostics and charging actions.

• Oil-filled cores reduce shock and vibration errors
• Dry dial feature for improved cold-weather responsiveness
• Calibration screws for field adjustment and recalibration
• Designed accuracy tolerance around 1.6%

Which refrigerants and service tasks can this manifold handle?

This Orion Motor Tech manifold is compatible with R1234yf, R404a and R134a, making it suitable for many automotive and small HVAC jobs. Use it to measure system pressures, evacuate lines, add refrigerant, and perform routine diagnostics on compatible systems.

• Works with R1234yf, R404a and R134a refrigerants
• Includes quick couplers for both R1234yf and R134a service ports
• Self-sealing can taps included for safe recharge operations
• Adapters provided for 1/4" male to 1/2" female LH & RH threads

What hose, fitting, and material features improve field reliability?

The set includes four 5 ft color-coded PVC hoses built with four reinforcement layers to stand up to service pressures and wear. The manifold body is machined aluminum and fittings are pure copper, delivering corrosion resistance, repeated hookups, and a lighter tool weight for mobile use.

• Four 5 ft color-coded hoses for safe, visible service lines
• Hoses rated for high-pressure use with 800 psi typical working pressure
• Aluminum manifold body reduces weight and resists corrosion
• Pure copper fittings for durable, leak-resistant connections

How quickly can I begin using the kit after purchase?

The OMT set ships with two quick couplers (R1234yf) and two (R134a), two self-sealing can taps, and two thread adapters so you can start basic charging and pressure checks immediately. No extra specialty adapters are required for the supported refrigerants, making it practical for technicians who service mixed fleets or different HVAC equipment.

• Ready-out-of-the-box: quick couplers and can taps included
• Two thread adapters for common service fittings (LH & RH)
• Useful for diagnostics, evacuations, and refill operations
• Compact kit suited to shop benches or mobile toolboxes

Who is this for: The Orion Motor Tech OMT 4-way manifold gauge set is aimed at automotive technicians, HVAC service professionals, and knowledgeable DIYers who need a versatile, road-ready tool for R1234yf, R404a and R134a systems. It suits anyone who values accurate pressure readings, durable construction, and a kit that includes the essential couplers and adapters for immediate use during maintenance and repair jobs.
