We offer welded and seamless Stainless Steel Capillary Tube in a wide range of sizes, with small diameter and bore, 304/304L and 316/316L stainless steels are available, they have high strength and good corrosion resistance characteristics, withstanding high pressure.
Capillary tube is usually a component of the device, it has a tight and close tolerance so that precise enough to install and joint other parts, capillary tube can be a very long coiled length, and occupy less space, and the internal diameter is often smaller, the surface should be clean both inside and outside surface, free from oil, grease and other particles.
