This brass male hex nipple reducer provides a reliable, compact connection between pipes with different NPT sizes. It transitions from 3/8 NPT on one end to 1/2 NPT on the other in a single 1 piece fitting. The hex body allows easy wrench tightening in tight spaces, while the allbrass construction delivers durability and corrosion resistance for a range of plumbing and pneumatic applications. Key benefits Size reduction and connection: connects a 3/8 NPT male thread to a 1/2 NPT male thread, enabling adapters between differing pipe sizes without additional parts. Durable brass construction: offers solid corrosion resistance and ageresistant performance in water, oil, and air systems. Easy installation: hex body facilitates wrench grip for secure tightening in tight spaces; compatible with standard NPT threads when used with pipe sealant or PTFE tape. Leakresistant performance: designed for reliable metaltometal seals when properly installed with appropriate sealing compounds. Compact profile: compact onepiece design fits into restricted or crowded installation areas. Key attributes Type: hex nipple reducer, male to male Ends: 3/8 NPT male on one end; 1/2 NPT male on the other Material: brass Quantity: 1 piece Connection standard: NPT (National Pipe Thread) Compatibility and suitability Fits standard 3/8 NPT and 1/2 NPT fittings and piping components Suitable for plumbing, irrigation, and light pneumatic systems that use NPT threads Works with pipe sealing methods such as PTFE tape or thread sealant to ensure a tight seal Applications Plumbing projects where a 3/8 NPT outlet must connect to a 1/2 NPT inlet Replacing or upgrading adapters in residential or light commercial water lines Bridging mismatched sizes in sprinkler and irrigation systems or compact workshop pneumatic lines Installation tips Clean threads before assembly and apply appropriate pipe sealant or PTFE tape to ensure a leak connection Handtighten first, then apply a wrench for a final snug fit; avoid overtightening to prevent thread damage Inspect the connection after installation and recheck for leaks during initial operation Notes This product is a 1 piece brass male hex nipple reducer with ends sized 3/8 NPT and 1/2 NPT Ensure compatibility with your system's pressure and material requirements before use Use with compatible fittings and care for brass components in accordance with standard plumbing practices
