Duramax Billet Heater Core Fitting Kit with Hose (WCF100699)

Preformed 1/2" heater hose with a billet aluminum quick-connect fitting that replaces the leak-prone factory heater core fitting on GM trucks. The billet fitting seals on serviceable O-rings and locks with a wire retainer clip, so it goes on and comes off without special tools.

Install the O-rings with lube and push the fitting on until the clip seats. Anodized billet aluminum.
