E36 heater core water pipe converter

all billet heater core hose adapter replaces the factory plastic part and allows use of standard heater hoses. The compact design allows easier routing of hoses for use on JZ swaps.

Machined from one piece of billet 6061 with OEM style O-rings seals, this adapter won't leak from any threaded hose barbs and installs easily with just the factory nut and stud from the original connection.

Machining from a single piece also make for a smaller profile giving more room for hoses in the cramped area BMW chose to put the connections.
