PB Motor Tech Vacuum Pump & Gauge Set — 4.5 CFM, Brass Manifold Gauge, R134A/R12/R22/R502

PB Motor Tech Vacuum Pump & Gauge Set: Efficient AC Service Tool

Engineered for both professional shops and dedicated DIYers, this 4.5 CFM vacuum pump paired with a brass manifold gauge offers a practical, reliable workflow for refrigerant charging and system diagnostics. Built to withstand daily use, it blends sturdy construction with thoughtful ergonomics to support a smooth service experience.

Premium Build and Readability

The manifold gauge is crafted from solid brass, featuring a clear sight glass window and oversized dials. The rubber-coated surface protects the display and improves grip, while enabling easy readings even in tight spaces or bright workshop lighting.

Complete Diagnostic Kit

Designed to cover freon charging and recovery tasks, the set includes everything you need in one package:

• 1 x 3-way manifold gauge
• 3 x 4 ft color-coded hoses
• 2 x R134a quick couplers
• 1 x puncturing can tap
• 1 x 410 adapter
• 1 x valve core tool

The hoses are color-coded to distinguish high, low, and charging lines, with a working pressure of 600 psi and a burst pressure of 3000 psi for confident operation across systems.

Performance and Ease of Use

A single-stage motor delivers 4.5 CFM of flow at 1/3 HP, helping speed up vacuum and recovery tasks. A reinforced aluminum housing supports heat dissipation and corrosion resistance, while an inlet filter prevents oil backflow and preserves pump health.

Ergonomics and Stability

The rounded sight glass on the oil tank makes oil checks quick, and the non-slip grip handle along with rubber feet minimizes vibration for stable placement during use.

Versatility and Care

Compatible with R134A, R12, R22, and R502 refrigerants, this kit covers a broad range of automotive and domestic AC systems. Note: the pump ships dry; add #32 or #68 oil before use to prevent motor issues. For support, contact us within 24 hours.

Real-World Use Scenarios

In a busy shop, technicians appreciate the 4-foot hoses for flexible reach, the color-coded lines for quick identification, and the ability to go from vacuum to charging smoothly. DIY setups benefit from an all-in-one kit that reduces tool clutter.
