Our quality of high pressure fuel injection tube for diesel engine is with high standard according to ISO8535, DIN73000.
Withstand high pressure: The oil drawing process makes the surface smooth which can improve its pressure bearing ability and make the fuel atomization process more completely. Then again the fuel can be burned more completely which increases the fuel efficiency and enlarge the accelerate power. The normal working pressure of our tube can be above 300bar.
High precision: Our tube tolerance OD and ID can control to +0.05/-0 or +0/-0.05
High elongation: The elongation can be controlled above 40%. After flaring, no defects can be found. And no crack exists after complete flattening and bending. The tube is suitable for complicate bending processing.
