Frequently asked questions
What sizes are hydraulic tubes available in?
OD 3 mm to about 127 mm (¼" to 5") typical, wall 0.5 mm to 12 mm; BWG or mm; straight lengths up to about 30 m, U-bent to drawing.
Which specifications cover hydraulic tubes?
Suits DIN 2353 / ISO 8434 fittings.
What are hydraulic tubes used for?
Clean, smooth bore. They're cold-drawn for precise dimensions, cleanliness and pressure capacity, in carbon steel (EN 10305-4) or stainless steel (ASTM A269 316L, duplex) for corrosive environments.
Which materials are hydraulic tubes available in?
Stainless steel, nickel alloys, carbon and alloy steel and non-ferrous metals, depending on the specification. See the material list above.
