This 1 piece brass pipe fitting is a male hex nipple reducer that connects 3/8' NPT to 1/2' NPT. Both ends are male NPT threads, and the hex body provides a convenient grip for tightening in tight spaces. Brass construction offers durability and good corrosion resistance for a range of piping and pneumatic applications. For a reliable seal, apply thread sealant or PTFE tape to the threads during installation. Key features and benefits Reduces from 3/8' NPT to 1/2' NPT with male threads on both ends, enabling a compact size transition in piping or tubing systems. Brass body delivers durability and corrosion resistance suitable for plumbing, air, and light industrial uses. Hex design on the body allows easy tightening with standard wrenches in tight or awkward spaces. Onepiece construction reduces potential leak points and simplifies installation. Compatible with standard NPT threaded components and fittings that use 3/8' and 1/2' NPT sizes. What's included 1 piece brass male hex nipple reducer, 3/8' NPT to 1/2' NPT Material and compatibility Material: Brass Ends: 3/8' NPT male to 1/2' NPT male Type: Hex nipple reducer Fits standard NPT threaded piping, valves, and fittings designed for 3/8' and 1/2' sizes Typical applications Connecting a 3/8' NPT valve, regulator, or connector to a 1/2' NPT line in a compact space where a direct connection is not possible or retrofit projects where two components with different NPT sizes must be joined General purpose use in plumbing, pneumatic, or light industrial systems that utilize NPT threads Installation notes Clean threads before installation Use appropriate thread sealant or PTFE tape on male threads to ensure a proper seal Handtighten, then snug with a wrench for a secure connection This description reflects the product's core design and intended use: a compact, durable brass hex nipple reducer that joins 3/8' NPT to 1/2' NPT with a singlepiece construction for reliable performance in various piping and pneumatic applications.
