Turbo Oil Drain Tubes



Turbo Oil Drain Tubes by Senior FlexonicsDiesel Thermal Management and Fluid Conveyance Solutions for Light-Duty, Commercial, Heavy-Duty and Off-Highway Applications.

Turbo oil drain tubes and feed tubes are a vital connection between the turbo and the oil lubrication system. Due to extreme heat, thermal expansion must be controlled to protect the turbo housing. The typical automotive engine compartment is a very hot and corrosive environment. The thermal expansion differences between the turbocharger and a short rigid pipe causes excessive loading against the turbo housing. The use of rubber hose is limited by temperature, adds assembly labor, and creates possible leak paths.

Senior Flexonics Advantage

Senior Flexonics has developed turbo oil tube solutions, utilizing our thin-wall, flexible metal tubing technology, that address engine vibration and thermal dynamics issues to ensure total system durability while aiding in assembly. A large variety of end configurations is available to reduce assembly time and reduce the number of components. Our unique ability to manufacture a simple one-piece design can also reduce the number of joints that are often prone to failures with many other designs.

Our design process includes many stages such as:

Initial Design

During the initial design stage of turbo oil feed tubes or drain tubes, we consider bolt access, clearance, orientation, and assembly to ensure there are no concerns.  Temperature fluctuations and movement frequencies are all analyzed and contemplated so the correct engineering course is taken as well as the correct materials are utilized for a durable final product. Often specialized stainless steel metal bellows are utilized by Senior Flexonics in the final tube assembly to mitigate thermal expansion and contraction as well as inherent engine and external vibrations at high frequencies. This is one of many differentiators in our approach vs. a simple rigid tube supplier.

Knowledge and Expertise  

Senior Flexonics is uniquely positioned in the industry as we have accumulated decades of field data regarding thermal management and movement characteristics.  This valuable information is applied to our products.  We understand metal characteristics and their inherent benefits of one type vs. the other.  Having the necessary on-site testing facilities to do extensive durability analysis including FE analysis to study heat and movement means we can assist you with complex 3D geometries and customize the flexibility vs. stiffness of the tube to meet installation constraints.

Manufacturing Capabilities

Senior Flexonics’ production facilities are equipped with an extensive range of dedicated tooling for bending, forming, and joining complete assemblies including advanced multi-axis Computer Numeric Control (CNC) bending machines, hydroforming and brazing to name a few. Some of these manufacturing cells are augmented by robotics for large production runs of OEM parts.

One Stop Shop

We are familiar with all standard turbo oil feed tube and turbo oil drain tube fittings (i.e. O-rings, heat shields, flanges) and can offer precision custom end fittings as required by the manufacturer. We further understand cleanliness requirements on feed and drain tubes are critical with extremely tight requirements that must be maintained. Our extensive experience with medical devices and strict ISO quality measures affords Senior Flexonics an additional industry leading advantage.


Senior Flexonics supplies flexible stainless steel turbo oil feed and drain tubes to many well-known vehicle brands. The turbo oil feed tube leads oil to the turbocharger of diesel and gasoline engines. Conversely, turbo oil drain tubes drain the oil from the turbocharger back into the block of diesel and gasoline engines. Our products are trusted by vehicle manufacturers because we understand the critical importance of:
