88-90 Chevy & GMC C/K Truck Suction Fitting w/Charge Port

This is the fitting that connect the accumulator, to the evaporator upper fitting at the firewall. The original did not have a charge port but our replacement one does, allowing the use of other compressor and hose assemblies that do not have the low side port. Compatible with R12 or 134a refrigerant, but the charge port is R12.
