This 1PC 45mm to 32mm OD 304 stainless steel weld concentric reducer is designed for homebrew piping systems. It allows a smooth, centered transition from a 45mm outer diameter tube to a 32mm outer diameter tube. The weld concentric design maintains alignment and minimizes flow disruption, providing a reliable, long lasting connection in brewing setups. Key benefits Concentric design for centered flow and reduced turbulence when changing pipe diameter from 45mm to 32mm OD. Welded construction for a strong, leak resistant joint suitable for hot liquids and brewing conditions. 304 stainless steel provides corrosion resistance and durability in water and wort contact. One piece construction minimizes leak points and simplifies installation. Compatible with standard metric sized tubing used in many homebrew systems (45mm and 32mm OD). Built for reliable performance in both temporary and semi permanent installations. Key attributes Functionality: weld concentric reducer to adapt pipe size while maintaining concentric alignment. Compatibility: suitable for 45mm OD and 32mm OD piping in homebrew setups. Size: transitions from 45mm OD to 32mm OD. Material: 304 stainless steel. Performance: corrosion resistant and durable for brewing environments. Quantity: 1 piece. Application: intended for homebrew piping and related equipment connections. Applications and use cases Connect a 45mm OD main line to a 32mm OD transfer line in a homebrew kettle, mash tun, or wort transfer path. Downsize from a larger diameter pump outlet to a smaller 32mm line to feed a filtration or transfer stage. Use as a replacement reducer in existing homebrew systems to restore a leak welded joint and maintain smooth flow. This product aligns with the specified 45mm to 32mm OD reduction, 304 stainless steel material, welded concentric design, and homebrew application. It is suitable for use in brewing environments where a robust, centered, and durable reducer is required.
