PB Motor Tech 3-Way Brass Manifold Gauge for R134A R12 R22 R502 — Brass Body, Large Rubber-Coated Dials

The PB Motor Tech 3-way brass manifold gauge is a robust HVAC service kit that lets technicians and skilled DIYers measure, charge, and recover refrigerants R134A, R12, R22 and R502 with durable brass construction and easy-to-read gauges.

Built for repeated field use, this PBMT manifold set pairs solid-metal construction with practical controls: three color-coded hoses, extra-large rubber-coated dials, a sight glass for fluid checks, and 1/4" straight quick couplers. The kit balances portability and toughness so you can carry it to automotive or domestic air conditioning jobs without sacrificing accuracy or endurance.

How does the PBMT manifold gauge help diagnose air conditioning issues?

The three-way gauges show suction and discharge pressures so you can identify leaks, blockage, or improper charge quickly. Readings from both low and high sides help you interpret system performance and determine next steps like evacuation, recharge, or repair.

• Dual large dials with rubber coating for clear, glare-resistant readings
• Sight glass window to observe refrigerant condition and flow
• Color-coded hoses (red/blue/yellow) to avoid connection errors
• Compatible with common refrigerants R134A, R12, R22, R502 for versatile diagnostics

What makes this manifold gauge durable and reliable on the job?

Components are made from high-grade brass and solid metal to resist wear, impact and corrosion encountered in service work. The lightweight but rugged housing keeps the tool portable while protecting internal valves and gauges during transportation and daily use.

• Brass body and metal fittings for long-term corrosion resistance
• Rubber-coated dial faces to prevent damage and improve grip
• Hoses rated 500 psi working pressure, 2500 psi burst pressure
• Compact design that fits easily into technician tool bags

How easy is it to set up and use for charging and recovery?

Setup is straightforward: attach the color-coded hoses to the appropriate service ports, connect the quick couplers, then read the gauges to control charging or recovery. The sight glass aids in confirming refrigerant movement while valves and large handles let you make measured adjustments.

• Three 4-foot hoses reduce tugging and allow flexible positioning
• Two 1/4" straight quick couplers speed connections and disconnections
• Large control knobs enable precise valve modulation even with gloves
• Works with standard refrigerants; no adapters required for listed types

Which safety and performance limits should I be aware of?

The hoses and fittings are rated for typical HVAC pressures but always follow refrigerant handling protocols and wear appropriate PPE. Use gauges and hoses within their working pressure and never exceed burst pressure ratings when pressurizing systems.

• Hose working pressure: 500 psi; burst pressure: 2500 psi
• Use only with compatible refrigerants: R134A, R12, R22, R502
• Follow local regulations and reuse guidelines for refrigerant handling
• Inspect hoses and couplers before each use to ensure integrity

Who is this for: The PB Motor Tech manifold gauge set is ideal for HVAC technicians, auto AC specialists and experienced DIYers who need a dependable, all-in-one service kit. If you require a portable, metal-bodied gauge set for routine diagnostics, charging and recovery on common refrigerants, this PBMT assembly delivers the durability and features needed for professional-style service work.
