SPD Oil return flex pipe SPD flex pipe in stainless steel is a simple solution to an oil return. Buy this and bend it to the right shape immediately and don't have to think about whether the pipe will fit the turbo you have chosen or another application. This can be used, for example, for oil filter removal, crankcase ventilation, oil cooler, vacuum, oil, water and more and also has swivel ends for easy installation. The tube is extremely flexible and can be bent to a small radius of only 9cm and is also made of stainless steel so it lasts a long time. Because the SPD flex hose is made of high quality stainless steel, this flex hose can be installed in the most exposed areas where it gets very hot near the cylinder head, exhaust manifold, turbo and exhaust system without the risk of damage or leakage damage to the flex hose Specification : Outer diameter : 27mm Total length : 550mm Size of clutches before flex : 44mm Thread:  AN10 Swivel Female Bending radius:  9cm~
