Brass Reducing Coupling 1/2" X 1/8" Female NPT Pipe Fitting Adapter Reducer This brass reducing coupling features a 1/2" NPT female thread on one end and a 1/8" NPT female thread on the other, making it ideal for connecting pipes, hoses, or fittings of different sizes in compressed air, gas, oil, or water systems. It's a reliable solution for creating compact, in-line transitions between components with mismatched thread sizes. Made from corrosion-resistant yellow brass, this fitting offers excellent durability and performance across a wide range of temperatures. With an overall length of 1-1/8", it delivers a secure and leak-resistant connection while maintaining a small footprint—perfect for tight spaces and general-purpose fluid handling.
