Product Description： This durable brass R134A service port features a ¼″ male leak-free operation and a ¼″ male to ½″ female transparent window. The transparent window allows for easy monitoring of oil level and quality, ensuring timely refills. The integrated fan helps remove heat quickly for safer and smoother operation.

The pump includes both ¼″ and ⅜″ inlets, along with a ¼″ to ½″ adapter to accommodate the most common HVAC hose sizes. The bundle includes a 3 Way AC Manifold Gauge Set for R134a R12 R22 R502, complete with anti-shock gauges, hoses, couplers, adapter, and puncturing can tap Freon recharge kit. Additionally, a 4cfm 1 Stage HVAC Vacuum Pump is included for R12 R22 R134a R410a systems.

The professional automotive AC tool kit consists of a 3-way gauge, 3 color-coded hoses, 2 adjustable 1/4'' quick couplers, a 1/4'' to 1/2'' Acme adapter, and a puncture-style can tap. This car AC gauge set is compatible with R134a, R12, R22, and R502 refrigerants, suitable for DIY and professional HVAC maintenance. It allows for pressure measurement, coolant evacuation, and refills, all housed in a heavy-duty blow-molded carrying case for convenient storage and transport.

The gauges feature a combination of dry and liquid-filled designs, with an oil-filled core for wear and shock resistance, and a dry dial for better winter performance. The moisture indicator monitors coolant condition, while calibration screws ensure ±1.6% accuracy. The PVC hoses are color-coded for easy identification, with blue for low, red for high, and yellow for charging. Each hose is reinforced with 4 layers to withstand pressures up to 600 psi.

Powered by a 1/3 hp all copper motor, the 4cfm vacuum pump provides fast and easy vehicle AC servicing. Its flow rate can draw systems down to 37.5 microns, ideal for degassing resin, epoxy, oil, and solvents. The kit includes lubricating and absorptive oil, as well as gloves for quick and clean oil refill. The reservoir features a sight glass and scale for easy monitoring, with 1/4 inch and 3/8 inch ports for servicing various systems.

The reinforced aluminum alloy casing dissipates heat efficiently and resists chemical corrosion, ensuring safe operation. The original design separates exhaust from oil vapor, further enhancing safety during use.
