Metal hose
Metal hose with 2S-shape lock, round, springy, high flexible, non-hermetic. The hose is mostly applied for mechanical protection of electric wiring (cables), tubes etc..
The metal hose consists of a protective jacket made by squeezing between rolls.
The jacket is a twisted tube made of a metal band which throughout the manufacture process is being profiled and spirally twisted in a flexible pipe. Connection and sealing between the spiral turns is achieved due to 2S-shape lock (see the picture of 2S-shape lock below). The material for the jacket is stainless band 0,3х8,0, 12Х18Н10Т, GOST 4986-79.
