In the basic configuration our heating hoses have armatures made of machining steel. We also offer armatures made of stainless steel (1.4301 / 1.4571) or other materials. The durability of the heating hose and armature should correspond. On request, the heating hoses can be equipped with loose flanges or integral flanges, according to DIN and ASA.
Please consider that armatures narrow the passage of the hose! See table on right.
