Field service couplers connect to our special Enviro-Guard hoses to allow access to service ports on automotive R-134a A/C systems. The quick-connect design has an integral safety sleeve, which protects against injury and refrigerant loss if the coupler is disconnected under pressure.

Product Features:

• Compact design to easily fit into tight quarters, especially handy for retrofits
• Six-ball couplers provide a more stable grip on the fitting than do couplers with four balls.
