Orion Motor Tech 3-Way AC Gauge Set for R134a/R410A/R404A/R22 — 5 ft Hoses, Hybrid Anti-Shock Gauges

This professional-grade manifold set bundles everything you need to service a wide range of vehicle and HVAC refrigerant systems: interchangeable adapters for multiple refrigerants, color-coded heavy-duty hoses, hybrid anti-shock gauges for accurate readings, and accessories such as self-sealing can taps and a moisture indicator. It brings durable construction and simple step-by-step guidance so both experienced technicians and DIYers can work more confidently on refrigeration and automotive AC systems.

How does this gauge set handle multiple refrigerants?

The kit includes R134a couplers plus R410A adapters and fittings for R404A and R22, allowing you to connect to different system service ports without switching tools. Quick-change adapters speed transitions between jobs and reduce cross-contamination risk when used correctly.

• R134a quick couplers included for common automotive systems
• R410A adapters convert connections for HVAC units
• 29° and other adapter fittings for specialized ports
• Self-sealing and piercing can taps for controlled refrigerant access

What makes the gauges accurate and durable?

The gauges use a hybrid anti-shock design that combines an oil-filled core to absorb impact and a dry dial for stable readings in cold environments. Each gauge offers a calibration screw for fine-tuning, maintaining close accuracy over long-term use.

• 2.6" high-and-low pressure dials with hybrid anti-shock construction
• Oil-filled movement resists wear and vibration
• Dry dial face preserves performance in low temperatures
• Calibration screw provides roughly 1.6% accuracy adjustments

Are the hoses and fittings built for heavy use?

The set comes with three 5 ft PVC hoses—blue (low), red (high), and yellow (service)—each reinforced in multiple layers to handle everyday pressures and offer a safety margin for bursts. Solid brass fittings and robust valves reduce leak points and stand up to frequent shop use.

• Three 5 ft color-coded hoses for clear high/low/service distinction
• Four-layer reinforced PVC rated for up to 600 psi working pressure
• Brass manifold body and fittings for corrosion resistance
• Self-sealing can taps minimize refrigerant loss during connection

What accessories and guidance are included for safe operation?

The kit is supplied with practical extras: a moisture indicator to quickly check system contamination, R134a can piercers for convenient charging, and a comprehensive instruction sheet that walks through setup, evacuation, and recharge steps. These additions help reduce user error and speed routine procedures.

• Moisture indicator for on-the-spot system condition checks
• R134a self-sealing and piercing can taps for refill tasks
• Step-by-step instruction manual for setup and service tasks
• Adapters and fittings for broader compatibility across systems

Who is this for? The Orion Motor Tech OMT 3-Way AC Gauge Set is aimed at automotive technicians, HVAC service professionals, and informed DIYers who need a versatile, durable manifold kit for multiple refrigerants. If you require a single, transportable toolset to diagnose, evacuate, and recharge various AC systems with clear gauges, long service hoses, and multiple adapters, this kit provides that capability with shop-ready construction and user guidance.
