EN 10305-4 Hydraulic Precision Steel Tube
Seamless precision steel tube to EN 10305-4 for hydraulic and pneumatic systems. Cold drawing brings the outside diameter and wall into a tolerance band that holds under bending and pressure, and the delivery conditions cover both bent lines and machined parts. Available from 6 to 100 mm outside diameter.
Price: quoted per specification. Steel prices move with the raw material market, so every quotation is confirmed at the time of order.
