PB Motor Tech 3 Way AC Manifold Gauge Set for R134A R12 R22

PB Motor Tech BMT 3-way AC manifold gauge set is a complete, professional-grade toolkit for charging, diagnosing, and servicing automotive and household air conditioning systems with R134a, R12, R22, and R502 refrigerants.

This compact kit brings together a brass 3-way manifold, large rubber-coated gauges, three color-coded 4-foot hoses, quick couplers, two can taps, a valve core tool, and a replacement parts kit so you can perform charging and recovery tasks with fewer trips to the parts store. Built to withstand workshop conditions, the set balances durability with clear, easy-to-read instrumentation and universal connections that suit both professional technicians and informed DIYers.

How does the gauge set make HVAC and car AC work easier?

The manifold centralizes pressure readings and control for both high- and low-side service, letting you manage refrigerant flow without swapping tools. Rubber-coated dials reduce glare and protect the instruments, while a transparent sight window helps you watch refrigerant movement during service. Color-coded hoses and quick couplers cut down connection errors and speed up setup.

• Brass 3-way manifold for corrosion resistance and long life
• Large, rubber-coated gauges for fast, accurate readings
• Transparent sight window to monitor refrigerant flow
• Color-coded red, blue, yellow hoses for correct connections

What refrigerants and systems are supported by this set?

This manifold gauge set is compatible with common refrigerants used in automotive and residential systems: R134a, R12, R22, and R502. It works for charging, pressure diagnosis, and basic recovery operations on vehicle air conditioners and household HVAC units, making it a flexible tool for many service needs. Always follow equipment and refrigerant-specific safety, handling, and environmental procedures.

• Compatible with R134a, R12, R22, and R502 refrigerants
• Suitable for automotive AC and household HVAC service tasks
• Includes both self-sealing and puncturing can taps for tank access

How durable and safe are the hoses, fittings, and gauges?

The three included hoses are heavy-duty, 4 ft in length, and color-coded to prevent mistakes during service. They are rated for 600 PSI working pressure and a 3000 PSI burst pressure, delivering the strength needed for routine charging and pressure tests. Brass fittings and quick couplers provide reliable seals and corrosion resistance for repeated use.

• 4 ft red, blue, and yellow hoses with high working/burst pressure ratings
• Brass fittings and quick couplers for secure, leak-minimizing connections
• Replacement parts kit and valve core tool included for onsite repairs

What accessories come in the set and why do they matter?

The package includes two quick couplers for high- and low-side attachment, one self-sealing can tap and one puncturing can tap for different refrigerant cylinder types, and a valve core tool plus a replacement parts kit to keep you working without delays. These extras mean fewer interruptions and a better chance of completing jobs on the first trip.

• 2 quick couplers for fast, correct high/low-side connections
• Self-sealing and puncturing can taps for varied tank designs
• Valve core tool and spare parts kit to maintain uptime

Who is this for: This PB Motor Tech BMT manifold gauge set is designed for automotive technicians, HVAC contractors, and DIYers who already handle refrigerants and require a robust, all-in-one toolkit. If you need versatile refrigerant support across multiple systems, straightforward gauge readouts, and a set that includes the common accessories for fieldwork, this kit is a practical choice.
