Capillary Tubes

Merinox offers a wide range of Seamless Capillary tubing, available in the following Stainless Steel, Nickel Alloys and Titanium grades: 316, 316L, 316Ti, 6Mo, 400, 825, C276 and Titanium Grade 2, either annealed (hardness < 180HV) or hard-drawn (hardness 260-330 HV).
Tolerances are according to EN10216-5 TC1/ISO 1127 D4/T3 or ASTM A 269/A 213.

Our capillary tubes are characterised by tight tolerances with precise dimensional accuracy, smooth bright surfaces and are also cleaned free from oil, grease and other       particles. This ensures an optimised flow of liquids and gases for a variety of industrial applications.

Our stock range starts from 2mm OD, available in thin, standard or heavy wall.
