Orion Motor Tech AC Manifold Gauge Set — 3-way with 5 ft Hoses for R1234yf/R134a, Oil-Filled Gauges

Orion Motor Tech's 3-way AC manifold gauge set is a complete professional-grade tool kit for measuring, evacuating and recharging vehicle air conditioning systems that use R1234yf, R404a or R134a refrigerants.

This compact manifold assembly combines rugged anodized aluminum construction with three color-coded 5-foot hoses, precision oil-filled gauges and quick-coupler fittings so you can diagnose system pressures and perform service tasks without juggling multiple adapters. Built with corrosion-resistant copper fittings, reinforced PVC hoses and calibration screws on the dials, the kit is intended to deliver reliable readings and long-term durability in workshop and mobile-repair environments.

How does the Orion gauge set measure system pressure accurately?

The set includes both high- and low-pressure gauges with oil-filled cores that dampen needle flutter and protect internal components from shock. Each dial has a calibration screw so you can verify and adjust accuracy, helping keep measurements within tight tolerances during routine maintenance.

• Oil-filled high and low gauges for stable readings
• Calibration screws to fine-tune accuracy
• Dry dial element for improved low-temperature performance
• Clear, color-contrasted faces for quick pressure checks

What connections and fittings are included for different refrigerants?

This manifold kit ships ready for multirefrigerant service: it contains two quick couplers compatible with R1234yf, two for R134a, plus a self-sealing can tap for each refrigerant type to simplify charging. Also included are left- and right-hand threaded 1/4" male to 1/2" female adapters to fit a range of vehicle service ports.

• Two quick couplers for R1234yf and two for R134a
• Self-sealing can tap for both R1234yf and R134a
• 1/4" male to 1/2" female adapters with LH and RH threads
• Standard 3-way manifold configuration for vacuum, charge and isolation

Are the hoses and body built to withstand workshop demands?

The three 5-foot hoses are PVC with four reinforcement layers to handle elevated service pressures and rough handling. The manifold body is machined aluminum with solid copper fittings to resist rust and keep leak paths to a minimum over repeated connections.

• Five-foot, color-coded hoses for reach and quick ID
• Four-layer reinforced construction rated for high working pressures
• Durable aluminum manifold body with corrosion-resistant copper fittings
• Robust shutoff valves and knurled handles for positive control

What tasks can you perform with this AC manifold gauge set?

This kit supports common HVAC service operations: pressure checks, vacuuming systems prior to recharge, and controlled refrigerant charging when paired with the appropriate supply. It’s designed to work across multiple refrigerants so one kit can cover many vehicle types and workshop jobs.

• Diagnose low-side and high-side pressures during troubleshooting
• Evacuate and monitor vacuum levels ahead of refrigerant fill
• Safely add refrigerant using self-sealing can taps and couplers
• Use adapters to fit a variety of OEM service ports

Who is this for: Automotive technicians, mobile HVAC service providers and experienced DIYers who need a durable, multi-refrigerant manifold set for routine diagnostics and servicing. If you require stable gauge readings, versatile fittings for R1234yf/R404a/R134a and long-lasting construction for frequent shop use, this Orion Motor Tech kit is built to meet those needs without requiring additional adapters or specialty tools.
