35mm Billet 10AN Turbo Drain Oil Flange for Mid-Frame Turbochargers

Stop fighting with generic, cast drain flanges that never quite seal right. This precision-machined 35mm billet 10AN turbo drain flange is built to do the job properly the first time.

Why This Flange Belongs on Your Build

Billet Construction, Not Cast

Machined from billet aluminium for a tighter grain structure, cleaner sealing surfaces, and far better durability than the cast flanges flooding import listings. This is the kind of part you install once and forget about.

Exact 35mm Bolt Pattern

Engineered specifically for mid-frame turbochargers with a 35mm centre-to-centre bolt spacing. No adapting, no guessing, and no mocking up multiple flanges before you find one that fits.

10AN Male Port

The -10 AN male port drops straight onto a standard braided stainless return line, helping keep your oil drain plumbing clean and leak-free whether you are running a gravity-drain or a scavenge pump setup.

Compact, Clearance-Friendly Profile

The low-profile design gives you the fitment flexibility you need when engine bay real estate is tight, which is a genuine advantage on builds where packaging matters.

Made in Canada by BSI Inc.

Produced domestically by Black Sheep Industries, this flange ships without the border delays, import duties, or currency-conversion headaches that come with ordering from U.S. suppliers. It is a quality Canadian-made part at a competitive price point, full stop.

A Clean Upgrade Over OEM

Whether you are replacing a worn factory cast flange or building fresh from the ground up — gas or diesel, street or race — the 35mm billet 10AN turbo drain flange is a straightforward, no-compromise upgrade.

Engineered for builders who expect precision — because your oil return line is no place to cut corners.
