What refrigerants does this kit work with?

This 4 CFM vacuum pump and gauge kit is A2L-ready and works safely with R32, R1234yf, and R454B — plus all traditional refrigerants including R134a and R410A. One pump, all systems.

What’s included in the kit?

Everything you need — 4 CFM vacuum pump, 3-way manifold gauge set, 3 color-coded hoses with lock valves, R134a & R1234yf quick couplers, self-sealing can taps, and necessary adapters. All in a carrying bag. Open and go.

Can I use this for mini-split installation?

Yes. The vacuum pump features 1/2" ACME and 1/4" SAE ports that fit most residential mini-splits, central HVAC, and automotive A/C systems.

How do I properly add oil to the pump?

Add oil slowly through the inlet. An internal baffle prevents splashing and reduces air bubbles. Fill to the center of the oil window. Check level before each use, and change oil every few jobs for optimal vacuum performance.

How long should I run the vacuum pump?

Run until the gauge reads 15 microns (2 Pa). Even after reaching vacuum, we recommend running for 15-30 minutes to fully evaporate any residual vapors inside the system — this prevents ice blockages and compressor damage.
