Orion Motor Tech 3‑Way AC Manifold Gauge Set R134a/R12/R22/R502, 3ft Color Hoses & Brass/Aluminum Manifold

Orion Motor Tech’s OMT 3-way AC manifold gauge set is a professional-grade refrigerant charging and diagnostic tool compatible with R134a, R12, R22 and R502, supplied with three 3-foot color-coded hoses and accessories.

This compact kit is built for automotive HVAC service tasks like pressure checks, charging, and basic recovery work. It combines robust metal gauges, extra-long hoses, and common adapters in a molded carrying case so technicians and DIYers can perform reliable measurements and make controlled refrigerant transfers on passenger cars and light trucks.

How accurate and durable are the gauges for routine HVAC checks?

The blue low-side and red high-side gauges are calibrated to cover the typical pressure ranges needed for vehicle systems. They mount in a solid brass and aluminum manifold body and use a clear, easy-to-read Fahrenheit dial to reduce misreads during shop work. The assembly is designed to withstand everyday knocks and drops encountered in garage environments.

• Blue gauge range: 0–350 PSI; red gauge range: 0–500 PSI
• Burst pressure rated to 3000 PSI; max working pressure 600 PSI
• Construction: solid brass, aluminum, PVC, and durable plastics
• Clear instrument faces for quick readings in bright or low light

What hoses and fittings come with the set, and how do they help workflow?

The kit includes three 3-foot hoses in red, blue and yellow for immediate visual identification of high, low and service lines. Each hose attaches with standard 1/4" fittings to the manifold and common quick couplers, enabling fast connection to vehicle service ports, refrigerant bottles, or recovery equipment. The longer hose length gives more reach around engine compartments and between vehicles and workstations.

• Three 3-foot hoses (red high, blue low, yellow service)
• 1/4" female hose fittings, plus 1/4" male quick couplers
• Can tap (piercing-style) for disposable cans and a 1/4" male to 1/2" female adapter
• Hoses designed for flexibility and resistance to kinking during use

Can a novice use this kit safely, and what documentation is provided?

Yes. The package contains a detailed parts diagram and step-by-step user manual that guide beginners through common tasks like pressure checks and basic charging. The included quick couplers and labeled hoses minimize connection errors, while the molded carrying case keeps components organized and protected between jobs.

• Step-by-step instructions for common AC service procedures
• Parts diagram to identify fittings and replacement pieces
• Cased kit keeps small adapters and couplers secure
• Helpful for both trained technicians and informed DIYers

What accessories are included to cover different service scenarios?

The set ships complete with multiple adapters and service fittings so you can handle different refrigerant bottle threads and quick-connect styles without buying extras. It’s designed to be a ready-to-use toolbox for troubleshooting and topping off refrigerant in most passenger vehicle systems that use the listed refrigerants.

• 1pc 3-way gauge manifold with 1/4" male ports
• 3pc 3-foot hoses with 1/4" female ends
• 2pc 1/4" male quick couplers and a can tap (piercing-style)
• 1pc 1/4" male to 1/2" female adapter, molded carrying case, manual

Who is this for: This Orion Motor Tech kit suits professional auto mechanics, HVAC technicians, and knowledgeable DIY vehicle owners who need a rugged, portable manifold set for refrigerant charging, pressure diagnostics and light recovery tasks. It’s intended for use with R134a, R12, R22 and R502 systems where standard 1/4" fittings and quick couplers are appropriate; always follow refrigerant handling regulations and vehicle manufacturer guidance.
