PB Motor Tech BMT 3-Way Brass Manifold Gauge Set for R134A/R12/R22/R502, Durable High-Pressure

Whether you work on car air conditioning or household HVAC, the PB Motor Tech BMT 3-way brass manifold gauge set gives you a complete, durable toolkit for measuring pressures, connecting to service ports, and adding or recovering refrigerant. Built from brass with large, rubber-coated dials and a clear sight window, this set was designed to withstand routine workshop use while keeping readings visible and hookups secure.

How does the manifold gauge measure and display system pressure?

The gauges use two large, color-coded, rubber-coated dials—one for high-side and one for low-side pressure—to deliver clear analog readings. A transparent sight window on the manifold body helps you watch refrigerant flow during charging and recovery operations.

• Dual gauges for high and low pressure.
• Rubber-coated dials reduce glare and resist impact.
• Transparent sight window for visual refrigerant monitoring.
• Brass construction reduces corrosion and extends tool life.

What comes in the kit and which fittings are included?

This PB Motor Tech BMT kit arrives ready for common service tasks: the 3-way manifold, three 4-foot color-coded hoses, quick couplers for R134a, a puncturing can tap, a 410 adapter, and a valve core tool. The included 1/4" male to 1/2" female brass adapter helps you match different port sizes quickly.

• 3-way brass manifold gauge.
• 3 × 4 ft hoses: red (high), blue (low), yellow (charge).
• 2 × R134a metal quick couplers and 410 adapter.
• Puncturing can tap and valve core tool included.

Are the hoses and couplers durable and safe for shop use?

The hoses are engineered for professional pressure ranges, with a 600 psi working pressure and a 3000 psi burst rating to handle standard refrigerants safely. Metal quick couplers and brass adapters provide secure connections that minimize leaks and withstand repeated attachment cycles.

• 600 psi working pressure; 3000 psi burst pressure.
• Color-coded for fast identification during service.
• Metal R134a quick couplers for robust, leak-resistant hookups.
• Brass fittings reduce galling and improve sealing longevity.
