3/8 NPT x 3/8 NPT solid brass male hex fittings, solid brass pipe adapter fittings, equal end connectors, 4 pieces

SIZE: 3/8 NPT to 3/8 NPT male brass equal hex fittings. CAUTION: The NPT tapered thread is a nominal size and does not represent the actual diameter. Please refer to the size chart for the specific thread diameter. The NPT thread has a 60° taper, which generally makes full tightening impossible.

MATERIAL: Premium solid brass fitting, thicker and stronger, durable, deep and precise thread, high corrosion resistance, low magnetic permeability, and high-temperature ductility. Quantity: 4 brass hex adapters.

FUNCTION: Allows you to connect female pipes of the same diameter or extend pipes. Suitable for plumbing, compressed air, hydraulic, refrigeration, instrumentation, and gas connections.

Working pressure: 1200 psi, temperature range: -53°C to +121°C. This type of connection is difficult to work with and, in most cases, does not require a gasket.

NPT tapered thread: The standard NPT tapered thread allows brass fittings to better conform to the object and strengthens the connection to prevent leaks. The thread is smoother, making installation easier and faster.
