PB Motor Tech BMT 3-Way Manifold Gauge Set for R134A R12 R22 R502 — Brass 3-Port Kit with Hoses & Case

The PB Motor Tech BMT 3-way manifold gauge set is a complete brass HVAC/R service kit for charging, testing and recovering R134A, R12, R22 and R502 refrigerants, supplied with hoses, adapters and a storage case.

Whether you service car air conditioners or household refrigeration systems, this compact kit groups the essential tools you need: a three-port manifold with large, easy-to-read dials, three color-coded 4-foot hoses rated to 600 psi working pressure, quick couplers, a puncturing can tap and a carrying case. Built from corrosion-resistant brass and finished with protective rubber on the gauges, it’s designed to be rugged enough for frequent shop use while remaining accessible for DIY maintenance.

How does the manifold gauge set simplify refrigerant charging and recovery?

The three-way manifold centralizes control of high, low and service ports so you can measure pressures, control flow and charge systems without swapping tools. Clear gauges and a transparent sight window let you monitor pressure and refrigerant level quickly while the included hoses and couplers make hookups straightforward.

• Three-port brass manifold for simultaneous control of high, low and service lines
• Large, easy-to-read dials with rubber protection for durability
• Transparent sight window to observe refrigerant level during use
• All connectors and hoses included to complete charging or recovery tasks

What refrigerants and applications is this kit compatible with?

This PB Motor Tech BMT set supports common refrigerants—including R134A, R12, R22 and R502—making it suitable for both automotive and household air-conditioning servicing. The included 410 adapter and universal quick couplers broaden compatibility with many service ports and fittings.

• Compatible with R134A, R12, R22 and R502 refrigerants
• Includes a 1/4" male to 1/2" female brass adapter and 410 adapter
• Quick couplers fit standard service connections used in vehicles and HVAC units
• Useful for diagnostics, charging and basic recovery operations

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

Hoses are built to withstand typical workshop pressures—600 psi working and 3000 psi burst—giving a safety margin for routine service. Brass construction resists corrosion while the rubber-coated gauges protect against shocks and handling wear, and the puncturing can tap and valve-core tool provide controlled, leak-minimizing access.

• Brass manifold and fittings for corrosion resistance and longevity
• Hoses: 4 feet long, color-coded, 600 psi working pressure
• Rubber-coated gauges reduce impact damage and improve grip
• Puncturing can tap and valve-core tool for secure service operations

What accessories are included and how do they help me work faster?

The kit is supplied with all the auxiliary parts needed to start service immediately: three hoses, two quick couplers, multiple adapters, a puncture tap and a valve-core tool, all organized inside a molded plastic case to keep parts protected and easy to find. These extras eliminate the need to source separate fittings before beginning a job.

• Three color-coded hoses (red, blue, yellow) for correct connections
• Quick couplers for fast, secure attachment to service ports
• Brass adapters and valve-core tool to prevent leaks while working
• Molded plastic storage case protects and organizes the complete set

Who is this for: The PB Motor Tech BMT 3-way manifold gauge kit is aimed at professional technicians and informed DIYers who need a ready-to-use, durable manifold solution for automotive and household refrigeration tasks. If you want a single, portable kit that covers common refrigerants, provides robust connectors and stores neatly in a case, this set is a practical choice.
