Round 4 inch stainless steel Instrument Tubing Seamless EN10216-5 TC1 A+P OD 1/2''
Hydraulic tubes and instrumentation tubes in a comprehensive range of corrosion-resistant stainless steels and nickel alloys covering outside diameters from (OD) 1.59 to 50 mm (0.0625 to 1.968 in.). All sizes are supplied with smooth surfaces and close dimensional tolerances reducing the risk of leakages when connecting tubes with couplings.
Standard delivery form for Spezilla hydraulic and instrumentation tube is straight lengths of 6 meters, but our tubes can also be delivered as coiled tubing, contributing to reduced installation costs.
Tubes with high cleanliness
Spezilla hydraulic tubes and instrumentation tubes are characterized by high cleanliness, and tubes with OD larger than 5 mm (0.196 in.) are delivered with plugged ends for transport protection against inside contamination.
