Orion Motor Tech AC Gauges – 3-Way Manifold Set for R1234yf/R404a/R134a

All-in-One AC Gauge Kit for Real-World A/C Service

Orion Motor Tech's AC Gauges offer a complete 3-way manifold set designed for automotive air conditioning work. Built for garages, shops, and dedicated DIYers, the kit blends rugged construction with clear, informative data in every task, from a quick charge to a full evacuation.

The core is a durable aluminum body paired with pure copper fittings, chosen for rust resistance and long-term reliability. The gauges feature an oil-filled core to dampen shocks and a dry dial that remains legible in cold starts. Calibration screws maintain accuracy within a tight tolerance, giving you consistent readings across jobs.

What’s Included and What It Delivers

• 3-way manifold with hoses and separate lines for R1234yf and R134a, enabling simultaneous monitoring and charging
• Two quick couplers for R1234yf and two for R134a, making connections quicker and cleaner
• One self-sealing can tap for each refrigerant to minimize spills during refills
• Two 1/4" male to 1/2" female adapters (LH & RH threads) to fit common service ports

Technical Benefits at a Glance

• High and low pressure gauges with an oil-filled core for steady, accurate readings
• Dry dial design improves visibility in chilly environments and reduces foggy displays
• Calibration screws ensure accuracy within roughly 1.6% for reliable service data

The hoses are color-coded for quick identification and safety, built with four reinforced layers to handle up to 600 psi in normal operation, with a robust burst strength of 3000 psi. This combination supports versatile use across several refrigerants and service scenarios.

In real-world use, technicians appreciate the tangible organization of hoses and fittings, the durable feel of the aluminum body, and the secure connections provided by the copper fittings. While results depend on technique and system condition, this kit offers a practical toolkit for measuring pressure, evacuating air, and refilling refrigerant with confidence.
