Orion Motor Tech AC Manifold Gauge Set — 3-Way with 5 ft Hoses, Brass Body & Large Dials

The Orion Motor Tech OMT 3-way AC manifold gauge set is a professional-grade tool kit for diagnosing, evacuating, and recharging vehicle air conditioning systems using R134a, R12, R22, and R502 refrigerants.

This compact kit brings workshop-capable pressure measurement, hose access, and safety gear into a single package. Designed for both home mechanics and professional technicians, the set combines oversized Fahrenheit dials, reinforced hoses, and brass construction to help you read system pressures, perform leak checks, and carry out evacuations or controlled refrigerant additions.

How does the OMT manifold gauge set help diagnose AC problems?

The gauges measure high- and low-side pressures so you can compare readings to expected values, revealing issues like low charge, a clogged orifice, or an overcharged system. The three-way manifold lets you isolate lines, vent, or connect a vacuum or refrigerant source quickly.

• Large Fahrenheit dials for fast, clear pressure readings
• Three-way manifold for simultaneous high/low monitoring
• Valve core depressor and 45° fitting for easier service access
• Compatible with R134a, R12, R22, and R502 refrigerants

Are the hoses and fittings durable enough for frequent garage use?

Yes — the included hoses are built for repeated service cycles. They feature a neoprene outer jacket for abrasion resistance and are rated with a 600 PSI working pressure and a 3000 PSI burst pressure for safety and longevity.

• 5-foot hoses for greater reach around vehicles
• Neoprene coating protects against wear and kinks
• Standard 1/4" female flare fittings on all hoses
• 45° bend on one end eases access to tight service ports

What construction and safety features are included?

The gauge-body and connectors use brass, aluminum, ABS, and rubber components chosen for corrosion resistance and repeated use. The kit also includes personal protective items so you can work more safely while performing refrigerant or pressure-related tasks.

• Solid brass fittings and aluminum manifold body for durability
• Thick rubber gauge covers for impact protection and grip
• Nitrile-coated work gloves and shatter-proof safety glasses included
• Detailed parts diagram and step-by-step instructions for reference

How easy is it for a DIYer to use this manifold gauge set?

The controls and reading surfaces are designed for approachable use by nonprofessionals, while remaining robust enough for shop technicians. The manual includes diagrams and stepwise guidance to help with common AC tasks, although basic knowledge of system pressures and safe refrigerant handling is recommended.

• Clear, large-font dial faces reduce reading errors
• Simple three-valve layout for common service procedures
• Instruction sheet and parts diagram assist troubleshooting
• Safety gear included for immediate protection during use

Who is this for? The Orion Motor Tech OMT 3-way AC manifold gauge set is aimed at car owners who perform their own maintenance, backyard mechanics, and professional technicians who need an affordable, full-featured diagnostic and service kit. It suits anyone servicing R134a, R12, R22, or R502 systems who values clear gauge readings, long-reach reinforced hoses, and the added safety of gloves and eye protection. Always follow refrigerant handling regulations and vehicle manufacturer guidance when using the kit.
