Hydraulic tubing and instrumentation tubing

Hydraulic tubes and instrumentation tubes in a comprehensive range of corrosion-resistant stainless steels and nickel alloys covering outside diameter (OD) 3 to 50 mm (0.118 to 1.968 inch). All sizes are supplied with smooth surfaces and close dimensional tolerances reducing the risk for leakages when connecting tubes with couplings.

Standard delivery form for Sandvik hydraulic and instrumentation tube is straight lengths of 6 meters, but our tubes can also be delivered as coiled tubing, contributing to reduced installation cost.

Tubes with high cleanliness

Sandvik hydraulic tubes and instrumentation tubes are characterized by high cleanliness, and tubes with OD larger than 5 mm (0.196 inch) can be delivered with plugged ends for transport protection against inside contamination.

Tubes in sizes according to ISO/EN

Seamless, stainless tubes in sizes according to ISO/EN. For sizes below 13.5 mm, please refer to Sandvik website to the product page for hydraulic and instrumentation tubes for further details.
