Threaded stainless fittings constitute the most common connection type for water, waste and ventilation systems made from stainless steel. Tibnor offers a wide range of threaded stainless fittings, encompassing sleeves, nipples, bushings, T-joints, bends, connectors and nuts. The material in these items is exclusively stainless steel of acid-resistant type, EN 1.4401 or 1.4404. These grades are in practice equivalent but formally, a slightly higher carbon content is allowed in 1.4401. Manufacture of stainless threaded fittings is usually based upon bar or hollow bar which is turned, milled or threaded.
