The 1PC 1/8' NPT to 3/8' NPT Male Hex Nipple Reducer Brass Pipe Fitting Connector is a singlepiece brass fitting with two male NPT threads of different sizes. One end is 1/8' NPT male and the other end is 3/8' NPT male. The hex body provides easy grip and wrenchassisted tightening for reliable installation. Key benefits Provides a compact, reliable size transition between 1/8' NPT and 3/8' NPT female ports in plumbing, pneumatic, and light hydraulic applications. Brass construction offers natural corrosion resistance and durability for a range of fluids and environments. Hex design enables secure grip and precise tightening, reducing the risk of crossthreading and leaks. Precision NPT threads support a tight seal when used with appropriate thread sealant or PTFE tape. Key attributes Functionality: NPT male to NPT male reducer nipple connecting 1/8' NPT and 3/8' NPT female ports. Compatibility: standard NPT thread; suitable for fittings and ports that accept 1/8' NPT or 3/8' NPT female threads. Size: 1/8' NPT male on one end, 3/8' NPT male on the other; hex body; singlepiece construction. Material: brass. Performance: durable and corrosion resistant; designed for reliable sealing when installed with proper thread sealant or PTFE tape. How to use Align the matching female ports (1/8' NPT and 3/8' NPT) and thread the reducer onto each, using the hex surfaces for wrench tightening. Apply appropriate thread sealant or PTFE tape as required by your system and test for leaks after installation. Use cases Pneumatic systems: connects a 1/8' NPT female sensor port to a 3/8' NPT air line port. Plumbing applications: bridges a 1/8' NPT female drain or fitting to a 3/8' NPT female port in compact spaces. Small hydraulic or irrigation setups: adapts between 1/8' and 3/8' NPT female components where space is limited. This fitting adheres to standard NPT specifications and is intended for use in assemblies requiring a 1/8' NPT to 3/8' NPT male hex nipple reducer in brass.
