Abstract
A spring-loaded pressure indicator inside the low side quick-coupler of the automotive air conditioner recharge hose. As the user adds refrigerant, the user can look at the pressure indicator on the quick-coupler to determine either the correct refrigerant charge has been reached or that it is approaching the correct refrigerant charge so that the user can stop charging and check the vent temperature in the passenger compartment.
