Nissan RB20DET RB25DET + Stock Garrett T3 Turbo Oil Drain Hose Kit

Oil Drain Solution for RB Engines Using the Factory Garrett Turbo

The factory-equipped Garrett T3 turbocharger used on RB20DET, RB25DET setups relies on a clean, unrestricted oil return to maintain CHRA health.

Over years of heat cycles, the original metal drain pipe and rubber hose on RB engines often become brittle, restricted, or begin leaking—a common cause of oil seepage, smoking, and poor turbo drainage.

When servicing the OEM turbo, replacing aging factory components, or refreshing a high-mileage RB engine, a new oil drain hose kit ensures proper routing and eliminates flow restriction while retaining compatibility with the original Garrett drain flange.

This Gryphontek turbo oil drain hose kit includes a CNC-machined factory-style Garrett drain flange, high-temperature NBR oil drain hose, mild-steel fittings, a 1 mm non-asbestos gasket, and high-tensile hardware, delivering a leak-free and dependable oil return system for RB engines still running the OEM turbo.
