Ask a Question
  • Can you charge the system with this?

    Yes you can, this would connect directly to the service port and to a vacuum pump or a container of refrigerant.

  • Is there a instructional video or a step by step guide to use this low side Charging Service Gauge Hose Set ?

    The blue hose connects to the service port on the unit and then the yellow hose connects to your vacuum pump. The blue hose is 5/16" ready to connect to the outdoor unit. The yellow is 1/4" for most vacuum pumps. The depicted valve isolates the gauge itself. This gauge also comes with a diagram on the packaging box.

  • is the fitting on the blue hose a low loss fitting?

    It is a flared, threaded connector. The service port uses a Schrader valve so some loss will be inevitable, the amount depends on how quickly it is disconnected.
