Hose wall made of ether grade (microbes and hydrolysis resistant) abrasion resistant Polyurethane (wall thickness between the spiral 0.4mm) with copper coated spring steel wire reinforcement. A very light and extremely flexible hose with good tensile strength and ultimate elongation. shore A ~85. Free of softeners, halogen and cadmium free and produced in line with FDA regulations. Hoses up to 90mm ID comes in roll form, whereas hoses from 100mm ID and above comes in compressed form for the sake of cost effective transportation. As the same is compressed after production, the hose will not retain the original measurement afterwards. Hence you may measure the same after fully elongating under pressure or go on counting rings as 1 Meter =41/42 rings for measurement purpose or use. The advantage of hose in compressed form is that the same can be ideally used between moving parts like CNC router etc as the hose behaves like a spring during onward and backward movements.
The above compressed variety can be produced with wall thickness 0.6mm and 0.9mm also (between the spirals), in case any of the applications demand such heavy hoses, but shall be supplied against specific orders only.
Also available in flame retardant and antistatic varieties.
