Machined from aluminum alloy and finished with an anodized surface, the DEF flange replaces the factory drain flange when you need a larger AN hose, a serviceable fitting, or when retrofitting a hybrid turbo. The kit ships with a high-temperature O-ring and mounting hardware so it arrives ready to install.\u003c\/p\u003e\n\n\u003ch3\u003eWhich turbochargers will this drain joint work with?\u003c\/h3\u003e\n\u003cp\u003eThe DEF flange is designed for common oil-cooled turbine housings with the 2-inch bolt spacing found on many T3 and T4 variants. It fits many T3\/T4 designs, T3-T4 hybrids and several GT and T6x series turbos, but is not compatible with TURT60 housings.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible: T3, T4, T3\/T4 hybrid housings\u003c\/li\u003e\n  \u003cli\u003eAlso fits: GT30, GT32, T60, T61, T66, T60-1, T70, SUPER 70\u003c\/li\u003e\n  \u003cli\u003eBolt hole center spacing: 2.0 in (51 mm)\u003c\/li\u003e\n  \u003cli\u003eNot compatible: TURT60 housings\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does this adapter prevent oil leaks and withstand heat?\u003c\/h3\u003e\n\u003cp\u003eDEF includes a 450°C-rated O-ring to seal the flange-to-turbo joint, reducing the risk of leakage and deformation under high temperatures.
