gpd 8221235 HVAC Heater Hose Fitting 5/8" Hose x 1/2" Male NPT

The gpd 8221235 is an HVAC heater hose fitting designed to connect heater hoses within a vehicle's cooling and heating circuit. Heater hose fittings like this one serve as the interface between the engine's coolant passages and the heater core, allowing hot coolant to flow into the cabin heating system and return to the engine. This fitting is sized at 5/8" hose x 1/2" Male NPT, making it a direct-connect solution for the appropriate heater hose and threaded port pairing.

Manufactured by gpd, this replacement fitting is built to restore a secure, leak-free connection in the heater circuit. Proper fitment of hose fittings is essential to maintaining coolant flow efficiency and preventing loss of cabin heat or coolant leaks at the hose junction.
