PB Motor Tech BMT 3-Way Manifold Gauge Set for R134A R12 R22 R502 — Brass Manifold, Case and Color-Coded Hoses

PB Motor Tech BMT 3-way manifold gauge set is a complete, heavy-duty refrigerant service kit for charging, testing, and recovering R134A, R12, R22 and R502 systems.

This professional-grade manifold gauge kit bundles a three-port brass manifold, oversized readable gauges, three color-coded 4-foot hoses, and a selection of service accessories in a molded storage case. Built for both technicians and experienced DIYers, the set balances durable construction and practical fittings so you can measure pressures, add refrigerant, or perform basic diagnostics on automotive and residential HVAC systems.

What comes in the kit and why does each part matter?

The kit arrives ready to use: the brass 3-way manifold is rust-resistant and the gauges have rubber protection for jobsite durability. Included accessories make common service tasks possible without searching for extra tools.

• 3-way brass manifold with T-style control knobs for precise flow control
• Two large, easy-to-read pressure dials with temperature scales
• Three 4-ft color-coded hoses (red, blue, yellow) rated 600 psi working pressure
• Quick couplers, valve-core tool, puncturing can tap, 410 adapter and 1/4" male to 1/2" female brass adapter

How accurate and durable are the gauges for regular service?

The gauges use corrosion-resistant brass and protective rubber boots to withstand workshop wear. Large faces and clear markings reduce reading errors, and the transparent sight window on the manifold lets you spot liquid refrigerant during charging operations.

• Durable brass body resists corrosion in humid environments
• Protective rubber coating minimizes impact damage
• Clear temperature scales and big numerals improve visibility
• Sight window helps monitor refrigerant flow during fill

Which refrigerants and jobs is this set suited for?

This manifold gauge set supports a range of common refrigerants — R134A, R12, R22 and R502 — so it covers most automotive and household air conditioning service needs. It’s ideal for pressure checks, evacuations paired with a vacuum pump, controlled charging, and leak-tracing workflows.

• Compatible with R134A, R12, R22 and R502 refrigerants
• Works for automotive A/C, refrigerators, and household HVAC maintenance
• Hoses rated to 600 psi working pressure and 3000 psi burst pressure
• Adapters and quick couplers fit widely used service ports

How does this kit simplify field use and storage?

Everything packs into a fitted plastic case so components stay organized and protected between jobs. The case reduces loss and speeds up setup, while color-coded hoses and labeled fittings cut down connection errors on busy work sites.

• Molded storage case keeps gauges, hoses and fittings organized
• Color-coded hoses for instant high/low/charge identification
• Compact layout speeds up job-site setup and teardown
• Heavy-duty fittings minimize leakage during use

Who is this for: technicians and skilled DIYers who perform routine refrigerant service, diagnostics, or charging on automotive and residential systems will find this set useful. It isn’t a replacement for certified recovery equipment required by regulatory bodies for large-scale refrigerant reclamation, but it does provide a complete, durable toolset for pressure checks, controlled charging, and everyday maintenance tasks.
