Machined from billet aluminum for strength and corrosion resistance, they let you repair the original breather plumbing quickly without resorting to permanent or costly modifications. The fittings are engineered specifically for 6.6L Duramax engines from model years 2001 through 2010 and are compatible with the factory locations and mounting hardware.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these fittings restore a damaged breather system?\u003c\/h3\u003e\n\u003cp\u003eThe PPE repair fittings replicate the factory connection points and thread sizes to replace stripped or corroded breather fittings.
