Heater Core Fittings
Replacement heater core fittings in billet aluminum construction, intended to replace the OEM standard plastic units. Plastic units become brittle with time, and are prone to failure and breaking. These billet aluminum units will bolt into the factory location, protrude through the firewall at correct factory angle, include new mounting hardware and new o rings. These replacement nipples do not include a built-in valve common to what some OEM applications may have. This means that when heat is turned off there will still be flow through the heater core. This is remedied by the hvac box diverting air away from the heater core. This may result in needing to turn your air a bit colder to achieve a middle ground temperature-wise in the mid range.
Offered in two variations: OEM standard barb and 10AN.
Applications: r32, s13, z32 (LHD applications flip barbs 180 degrees)
