Orion Motor Tech 3-Way AC Manifold Gauge Set for R134a/R12/R22/R502 — 3 ft Hoses, High/Low Gauges

The OMT 3-way AC manifold gauge set is a professional-grade diagnostic and charging kit designed to measure, charge, and assist recovery for R134a, R12, R22 and R502 systems with long 3-foot hoses for safer, easier access.

This heavy-duty manifold gauge assembly from Orion Motor Tech gives technicians and DIYers a compact, ready-to-use solution for automotive and light commercial refrigeration work. Built with a blue low-pressure gauge (0–350 PSI), a red high-pressure gauge (0–500 PSI), and burst protection up to 3000 PSI, the set combines robust materials, clear instrumentation, and a complete accessory pack so you can connect, read, and service refrigerant circuits quickly. The included 3ft color-coded hoses improve reach and reduce stress on fittings during service.

How accurate and durable are the gauges for routine shop use?

The gauges use easy-to-read Fahrenheit scales calibrated for common refrigerants and are housed in solid brass and aluminum construction to resist shop wear. Their clear faces and marked ranges make pressure interpretation quick while the sturdy build reduces damage from drops and rough handling.

• Blue low-pressure gauge: 0–350 PSI range for suction readings.
• Red high-pressure gauge: 0–500 PSI for discharge readings.
• Burst pressure rating up to 3000 PSI and max working pressure 600 PSI for built-in safety margin.
• Rugged materials: brass, aluminum, PVC and impact-resistant plastics.

What hoses and fittings come with the set, and why does length matter?

This kit includes three 3-foot color-coded hoses—red (high), blue (low), and yellow (service)—with 1/4" female fittings to match common service ports. Longer hoses give better clearance from hot engine components and improve mobility when connecting to rooftop or ground-level units.

• Three 3ft hoses for extended reach and safer connections.
• Color coding (red/blue/yellow) to prevent cross-connection errors.
• Two quick couplers (1/4" male) and one piercing-style can tap for convenient access.
• 1/4" male adapter to 1/2" female included for compatibility with different fittings.

Can a beginner use this manifold set safely for basic charging and diagnosis?

Yes—Orion Motor Tech supplies a detailed parts diagram and step-by-step manual to guide novice users through typical charging and diagnostic tasks. While the kit is user-friendly, always follow refrigerant handling regulations and wear appropriate PPE when connecting and charging systems.

• Comes with a comprehensive user manual and parts diagram.
• Included can tap (piercing-style) simplifies working with refrigerant cans.
• Clear gauge markings reduce confusion during charge and recovery checks.
• Use recommended safety gear; follow local refrigerant laws and guidelines.

What exactly is included in the Orion Motor Tech package?

The kit ships as a complete service bundle so you can begin testing and charging right away. Components are stored in a custom molded case for transport and organized storage between jobs.

• One 3-way manifold with 1/4" male ports and dual gauges.
