Stainless Steel Capillary Tube

We offer welded and seamless Stainless Steel Capillary Tube in wide range sizes, with small diameter and bore, 304 and 316L stainless steels are available, they have high strength and good corrosion resistance characteristics, withstanding high pressure。

Capillary tube is usually component of device, it has 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, the internal diameter is often smaller, surface should be clean both inside and outside surface, free from oil, grease and other particles.
