TURBO OIL DRAIN ADAPTER

Turbo oil drain adapters are critical components that allow you to connect an oil return line to your turbocharger's bearing housing, typically using a flange with two bolt holes. Choosing the right one depends primarily on your turbo's bolt hole spacing and your preferred fitting type (like -10AN or a hose barb).

Key Selection Factors
Bolt Spacing: Common sizes include 38-44mm (small frame/GT series) and 50.8mm (standard T3/T4). Measure your turbo's outlet before buying.
Sealing: Modern adapters often use an O-ring seal rather than a paper gasket, which is generally more reliable against leaks under high heat.
Clearance: If your turbo housing is bulky, look for extended or angled (e.g., 20° or 45°) adapters to ensure the drain line can clear the compressor or turbine covers.

Our Turbo Oil Drain Adapter with O-ring seals eliminates the use of a gasket for a positive leak-free seal.
