This durable and versatile tool performs three time saving service tasks:

  1. Removal and replacement of service valve cores without losing system charge.
  2. Temporary removal of valve cores for quicker, more complete recovery, evacuation, and recharge.
  3. Calculation of superheat with excellent accuracy by reading refrigerant temperature and pressure from the same location in the system.
