Precision Capillary AMS Seamless Tube is designed for aerospace, instrumentation, thermal control, and precision fluid transmission applications where small diameter, tight tolerance, and reliable material performance are required. With excellent straightness, roundness, concentricity, and surface quality, this product is suitable for high-precision systems that require stable flow, accurate assembly, and clean tube ends.
As a type of AMS stainless steel tubing, this precision capillary seamless tube can be supplied for aerospace projects requiring AMS 5560 tubing, AMS 5560 stainless steel tube, AMS 5570 tubing, and AMS 5570 stainless steel tube. It is suitable for customers who need small-diameter aerospace stainless steel tubing with strict dimensional control, material traceability, and certified documentation.
Compared with general industrial tubing, aerospace capillary tubing requires better control of inner diameter, outer diameter, wall thickness, length, surface finish, and end processing. Huashang can support customized production according to drawings, samples, AMS requirements, tube size, material grade, and inspection documents.
Capillary tubes have significant advantages in geometric accuracy and surface quality, not only possessing excellent straightness, roundness, and concentricity, but also controlling surface roughness at an extremely low level.

Its dimensional accuracy is excellent, with deviations in inner diameter, outer diameter, wall thickness, and length strictly limited to a very small range. At the same time, the quality of pipe end processing is superior, fully meeting the stringent requirements of high-precision application scenarios.
