Description

Use gauges for air conditioning and refrigerators, but the hoses couldn’t fit on a automobile air conditioner?
--- Buy these now, you can hook up your HVAC gauges to these and the quick coupler adapter hooks easily to the low and high side ports on a car to check pressure readings on gauges and charge refrigerant to low side port

It was time to replace the ones that I had with a new set of coupling service valves, which are far less expensive than purchasing a new manifold gauge set or a new set of hoses that have the service valves installed!
