AMC Professional Manifold Gauge Set
AMC Professional Manifold Gauge Set
The AMC Professional Manifold Gauge Set is a complete HVAC/R service and diagnostics kit built for accurate refrigerant charging, evacuation, and pressure testing. Color-coded high- and low-pressure dials, an aluminum valve body, and solid brass fittings deliver dependable, leak-resistant performance in the workshop or on-site — whether you're servicing a mortuary cooler, walk-in refrigeration, automotive A/C, or small-scale refrigeration equipment.
Key Features
- Complete manifold gauge kit: 3-way (or 4-way) manifold gauge, three color-coded hoses, R134a/R1234yf quick couplers, sealed can taps, adapters, a screwdriver, and a valve core wrench — all packed in a durable carry case.
- Works with four refrigerants: accurately measures pressure for R134a, R404A, R1234yf, and R22 across automotive A/C, household refrigerators, and small refrigeration systems.
- Clear dual-scale gauges: color-coded high/low dials with Fahrenheit temperature scales and a sight window; calibration screws hold ±1.6% accuracy.
- High-pressure sealing hoses: three 5 ft heavy-duty rubber hoses rated for 800–4000 PSI working pressure with gasketed brass connectors to reduce leakage and loosening during service.
- Durable metal construction: aluminum valve body and solid brass fittings tested for repeated operation in workshop and field environments.

Frequently Asked Questions
Which refrigerants does this gauge set support?
It reads pressure for R134a, R404A, R1234yf, and R22. Choose the refrigerant-marking option that matches your service work; the 4-way channel option adds an extra port for faster evacuation and charging.
What is the difference between 3-way and 4-way?
A 3-way manifold has low, high, and a service/charge port. A 4-way adds a dedicated vacuum port so you can pull a vacuum and charge without swapping hoses.
Is it accurate enough for professional service?
Yes. Calibration screws maintain ±1.6% accuracy, and the sight window helps assess charge level during testing.
