Solder fittings, also known as capillary fittings, are short sections of smooth pipe designed to slide over the outside of the mating tube. Solder wire is fed then around the edge of the fitting and heated to seal it. Stainless steel solder fittings benefit from the metal’s strength, resistance to corrosion and ease of cleaning.What are stainless steel solder fittings used for?Stainless steel solder fittings are used in many industries, including those which require pipes and fittings to transport and come in contact with food, beverages, or other products, and thus have strict hygiene practices.
