PB Motor Tech BMT 3-Way AC Manifold Gauge Set for R134A R410A R22 R404A — Aluminum, 600 PSI Working, Color-Coded Hoses

PB Motor Tech BMT 3-way AC manifold gauge set is a complete, corrosion-resistant diagnostic and charging kit for R134A, R410A, R22 and R404A systems.

Whether you service car air conditioning, home HVAC or refrigeration units, this manifold gauge set brings full functionality and durable construction into a single kit. Built from aluminum with protected dials and clear sight windows, the set includes hoses, quick couplers, a puncturing can tap and adapters so you can measure, charge or recover refrigerant with confidence. The components are color-coded and rated for high working pressures to match common refrigerants and professional tasks.

How does this manifold gauge set help diagnose AC system issues?

The gauges let you read system pressures on both the high and low sides simultaneously, which is essential for spotting leaks, blockages, or improper refrigerant charge. Clear, large dials and a sight window make readings fast and accurate under typical workshop conditions.

• Dual large dials for high and low side pressure monitoring
• Transparent sight window for visual refrigerant level checks
• Color-coded hoses minimize connection errors during diagnostics
• Corrosion-resistant aluminum construction for reliable service life

What comes in the kit and which tasks can I perform with it?

This kit contains everything needed for routine freon charging, pressure testing, and basic recovery or maintenance jobs. It’s designed to let both DIYers and technicians perform common AC tasks without aftermarket add-ons.

• 3-way manifold gauge with protective rubber coating
• Three 4-foot color-coded hoses (red, blue, yellow)
• Two R134a quick couplers, a puncturing can tap and a 410 adapter
• Valve core tool and brass 1/4" male to 1/2" female adapter

Are the hoses and fittings durable enough for professional use?

The hoses are rated to handle common workshop pressures and the included metal couplers and brass adapters are built for repeated connections. A tested burst pressure and rugged materials reduce downtime from hose failures.

• 600 psi working pressure, 3000 psi burst pressure for safety margin
• Metal quick couplers and brass adapters for robust connections
• 4-foot hose length for convenient reach around vehicles or units
• T-type knob on puncturing can tap for controlled can piercing

Which refrigerants and applications is this set compatible with?

The PB Motor Tech BMT manifold gauge is compatible with the most commonly used refrigerants in automotive and light commercial HVAC. It supports charging and basic recovery operations across a range of systems when used according to refrigerant-handling guidelines.

• Compatible with R134A, R410A, R22 and R404A refrigerants
• Suitable for car A/C, household air conditioning, and small refrigeration units
• Includes adapters for R134a and 410 applications
• Useful for both hobbyist maintenance and professional service checks

Who is this for: Technicians and experienced DIYers who need a compact, all-in-one manifold gauge set for routine diagnostics, charging and simple recovery tasks. If you require high durability, clear pressure readouts and a kit that covers multiple refrigerants, the PB Motor Tech BMT set supplies the necessary tools. It’s not a full-service recovery machine—use appropriate safety and refrigerant handling procedures and follow local regulations when performing refrigerant work.
