PB Motor Tech Manifold Gauge Set with 4.5 CFM Vacuum Pump

This PB Motor Tech manifold gauge set features a durable brass construction with a sight glass for checking refrigerant levels. The extra-large, rubber-coated dials ensure easy reading and protection. The complete set includes a 3-way gauge, three 4-foot color-coded hoses (500 psi working pressure), and 2 1/4" quick couplers, suitable for R134A, R12, R22, and R502 refrigerants. The single-stage vacuum pump has a 1/3 HP motor, 4.5 CFM flow rate, and can reach 5 Pa (37.5 microns). Its reinforced aluminum alloy housing dissipates heat and resists corrosion, while the sight glass on the oil tank allows for clear monitoring. Please note: vacuum pump is shipped without oil and requires #32 or #68 oil before operation.
