PB Motor Tech 4.5 CFM Vacuum Pump with Brass Manifold Gauge Set for Auto & Household AC Maintenance

Overview

The PB Motor Tech 4.5 CFM Vacuum Pump paired with a Brass Manifold Gauge Set is designed for both automotive and domestic air conditioning work. Built with durable brass and a sturdy aluminum body, this kit balances resilience with precise readings. The sight glass on the oil tank lets you monitor oil levels at a glance, while the large, rubber-coated dials make performance results easy to read in busy work spaces. Three color-coded hoses keep high, low, and charging tasks clearly separated, helping technicians stay organized on a crowded bench or in a tight engine bay.

Designed for practical versatility, the kit brings together a single-stage vacuum pump with a 1/3 HP motor, delivering a steady 4.5 CFM of flow. It can evacuate systems down to 5 Pa (37.5 microns), while the reinforced aluminum housing aids heat dissipation and resists corrosion. Two non-slip, rubber-bottom feet stabilize the setup, and the hose assembly—4 feet long—offers ample reach when working in vehicle trunks or appliance cupboards.
