PB Motor Tech Vacuum Pump Kit with 4-Way Manifold Gauge & Leak Detector — 4.5 CFM, ±1.6% Accuracy, Storage Case

The PB Motor Tech Vacuum Pump Kit is a professional-grade automotive and home AC service set that combines a 1/3 HP single-stage vacuum pump, a 4-way manifold gauge, leak detector, and all essential adapters and hoses for evacuating, testing, and recharging refrigeration systems.

This all-in-one kit is built for mechanics, DIYers, and maintenance technicians who need a reliable package to service R134a, R22, and R410a systems. The package pairs a robust 4.5 CFM vacuum pump in an aluminum housing with a large, easy-to-read 4-way manifold gauge, color-coded high-pressure and low-pressure hoses, and a puncture can tap plus quick couplers. Accessories come organized in a storage case so you can carry and use the kit on the job without hunting for parts.

How does the manifold gauge ensure accurate readings?

The PB Motor Tech 4-way manifold gauge features oversized dials and precision internals that deliver an accuracy of approximately ±1.6%, making it suitable for routine diagnostics and charging. The color-coded hoses and sturdy fittings help prevent mix-ups and withstand high working and burst pressures for safe use.

• Large gauge dials for quick, legible readings
• ±1.6% accuracy for reliable pressure checks
• Color-coded hoses: red (high), blue (low), yellow (charge), black (vacuum)
• Rated for 600 psi working and up to 3000 psi burst

What makes the vacuum pump suitable for regular AC service work?

The vacuum pump uses a copper-wound motor and reinforced aluminum-alloy housing to deliver a 4.5 CFM flow rate that removes moisture and non-condensables efficiently. Its two intake sizes (1/4 in. SAE and 1/2 in. ACME) accommodate different port fittings, and the rugged construction helps with heat dissipation and corrosion resistance for long service life.

• 1/3 HP motor with copper construction for durability
• 4.5 CFM flow for effective evacuation of systems
• Reinforced aluminum-alloy housing for heat control and corrosion resistance
• Dual intake threads (1/4" SAE and 1/2" ACME) for versatile connections

Which accessories are included and how do they help on the job?

The kit contains a practical set of adapters, hoses, couplers, and a puncture can tap so you can complete most AC tasks without buying extra parts. Small items such as Teflon tape, gloves, and a storage bag keep the kit job-ready and organized, while the quick couplers and adapters speed up hookup and reduce downtime.

• R134a puncture can tap and quick adapters for refrigerant access
• Four 48" color-coded hoses for standard service reach
• Straight and angled SAE adapters plus two quick couplers
• Storage case, Teflon tape, gloves, and organization bag included

Is this kit compatible with different refrigerants and systems?

Yes—the PB Motor Tech set is designed to work with common refrigerants such as R134a, R22, and R410a, so it fits many automotive and residential HVAC scenarios. Keep in mind the kit does not include vacuum pump oil due to shipping restrictions, so plan to supply the recommended oil before first use.

• Compatible with R134a, R22, and R410a refrigerants
• Works for automotive AC and many household HVAC units
• Vacuum pump oil must be purchased separately
• Comprehensive accessories reduce need for extra purchases

Who is this for: The PB Motor Tech Vacuum Pump Kit is ideal for independent mechanics, automotive technicians, HVAC contractors, and experienced DIYers who perform routine evacuation, leak testing, and refrigerant charging. It suits anyone needing a portable, organized kit that covers the core tools for system diagnosis and servicing—especially when compatibility with multiple refrigerants and robust manifold accuracy are priorities.
