Orion Motor Tech AC Gauge Set with 5 ft Hoses — Hybrid 68mm Gauges, R134a/R12/R22/R502

The Orion Motor Tech OMT AC Gauge Set is a full professional-grade manifold gauge kit for diagnosing, evacuating, and recharging automotive and HVAC systems using R134a, R12, R22, or R502.

This manifold gauge set combines durable components and versatile fittings to let mechanics and experienced DIYers read low and high pressures, attach to varied refrigerant cans, and perform charging or evacuation tasks. The kit balances rugged field use with clear, winter-ready gauges and a selection of adapters and can taps so you can work with older and newer refrigerants without hunting extra parts.

How does this gauge set measure and display system pressure?

The OMT set uses two 68 mm hybrid anti-shock gauges—one for low and one for high pressure—designed to resist impact while remaining accurate in cold conditions. The gauges pair an oil-filled core for vibration protection with a dry dial face for readable performance in lower temperatures.

• 68 mm low and high pressure gauges with hybrid construction
• Dry dial for clear readings in cold weather
• Oil-filled movement to reduce wear and shock damage

What hoses, couplers, and adapters are included for connecting to systems?

The kit supplies three 5-foot color-coded PVC hoses—blue (low), red (high), yellow (service)—each built with four reinforced layers for daily working pressures up to 600 psi and a burst rating up to 3000 psi. Two adjustable 1/4" quick couplers and a 1/4" to 1/2" Acme adapter broaden compatibility with common service ports and refrigerant cylinders.

• Three 5-ft hoses with four-layer PVC reinforcement
• Blue, red, yellow color coding for fast identification
• Adjustable 1/4" quick couplers and 1/4"-to-1/2" Acme adapter included

Which refrigerants and service tasks can I perform with this kit?

This manifold set is built to work with R134a, R12, R22, and R502 refrigerants, so it supports a wide range of automotive and light HVAC systems. Use it to read system pressures, recover or evacuate lines when paired with a pump, and refill systems using either puncture-style or self-sealing can taps depending on the refrigerant container.

• Compatible with R134a, R12, R22, R502 refrigerants
• Includes both puncture and self-sealing can taps for old and new cans
• Suitable for pressure checks, evacuations, and controlled charging

How durable and service-ready is the hardware for everyday shop use?

The components are manufactured for repeated professional use: reinforced hoses resist kinking and pressure spikes, the hybrid gauges withstand shocks, and the quick couplers provide secure, adjustable connections. The kit’s variety of fittings and taps reduces the need to buy extra adapters when switching between different vehicle models or refrigerant can types.

• Four-layer reinforced hoses with 3000 psi burst rating
• Hybrid anti-shock gauges for longevity and winter clarity
• Multiple couplers and taps to fit varied service scenarios

Who is this for? Technicians, HVAC professionals, and experienced DIY vehicle owners who service air conditioning systems will find this Orion Motor Tech kit useful. It’s designed for people who need dependable readouts, broad refrigerant compatibility, and a complete set of connectors and taps to tackle both diagnostic checks and charge/evacuation tasks without frequently sourcing extra parts.
