PB Motor Tech 3-Way Brass Manifold Gauge Set for R134A/R12/R22/R502 — 3 Color-Coded Hoses, Large Dials

PB Motor Tech's 3-way brass manifold gauge set is a complete, durable HVAC service kit for charging and diagnosing systems using R134A, R12, R22 and R502 refrigerants.

This compact kit combines a brass 3-way manifold, large coated dials, three color-coded 4-foot hoses and several practical accessories so you can read pressures, add refrigerant, or recover charge more efficiently. Built for regular shop use and serious DIY maintenance, the set balances corrosion resistance and clear, easy-to-read instrumentation for automotive and light commercial air conditioning work.

How accurate and durable are the gauges for everyday shop use?

The gauges use oversized faces with rubberized bezels for shock protection and clearer readings in busy environments. Brass construction throughout the manifold improves corrosion resistance versus cheaper alloys, and the transparent sight window helps you monitor refrigerant flow while charging.

• Brass 3-way manifold resists corrosion and wear
• Large, rubber-coated dials reduce glare and damage
• Sight window offers visual refrigerant monitoring
• Suitable for routine automotive and household AC diagnostics

What hoses and fittings are included and what pressures do they handle?

The kit includes three 4-foot color-coded hoses — red for high, blue for low, and yellow for service/charging — sized for typical HVAC service. Each hose is rated for 600 psi working pressure and 3000 psi burst pressure, giving a strong safety margin for standard refrigerants and service operations.

• Three 4-foot color-coded hoses for clear connection identification
• 600 psi working pressure; 3000 psi burst pressure
• Durable metal quick couplers for R134a service ports
• Includes adapter to fit varying port sizes for versatile hookup

Which accessories come with the set and how do they expand usability?

The package ships with quick couplers, a puncturing can tap, an adapter and a valve core tool so you can handle a range of service tasks without buying extras. These accessories simplify common jobs like tapping R134a cans, adapting different service port threads, and replacing valve cores on the fly.

• Two R134a quick couplers for fast, leak-minimized connection
• Puncturing can tap with T-style knob for controlled can access
• 1/4" male to 1/2" female brass adapter for port compatibility
• Valve core tool included for in-field core changes

Can this manifold gauge set handle multiple refrigerants safely?

The PB Motor Tech manifold is built to work with a range of common refrigerants — R134A, R12, R22 and R502 — when used according to service guidelines. It offers the fittings and pressure ranges that match those refrigerants, but always verify refrigerant compatibility and follow safe service practices for each system.

• Compatible with R134A, R12, R22, R502 refrigerants
• Color-coded hoses reduce cross-connection risk
• Brass components provide chemical and mechanical robustness
• Use with appropriate safety gear and refrigerant-handling procedures

Who is this for: technicians, mobile mechanics and experienced DIYers who need a dependable, all-in-one manifold gauge kit for automotive and small commercial AC work. If you want a corrosion-resistant manifold, clear instrumentation, and practical accessories for routine charging, recovery and diagnostics, this PB Motor Tech set covers the essential tools in a single, transportable package.
