## Long description

VIEGA stainless steel reducing coupling 18×15 mm SC model 436223 is a compact coupling designed to connect pipes of different diameters in plumbing and heating systems. Made from stainless steel, it offers corrosion resistance and mechanical strength for reliable joints in residential and commercial installations. The SC reducing coupling provides hydraulic sealing suitable for stainless steel pipes and other compatible materials, ensuring a compact connection with consistent flow characteristics.
Advantages
The stainless steel construction delivers long-term corrosion resistance and durability in potable water, heating and general plumbing applications. The reducing shape enables a smooth transition between 18 mm and 15 mm pipes while maintaining hydraulic integrity.
