Brass fitting, female-to-male reducer 3/8"X1/4"

The brass fitting, nut–male reduction 3/8" x 1/4" is a compact installation component designed for reliable transition between two different thread sizes in domestic and professional plumbing systems. It supports precise adaptation of pipework and accessories where a G3/8 connection must be safely reduced to G1/4.

The reduction features a nut–male connection type, so one side tightens with a wrench while the opposite male thread engages directly with the mating element. The 21 mm hex profile offers a secure grip for tools, which helps achieve a tight, stable joint and reduces the risk of leaks in everyday operation.

The solid brass body delivers high resistance to corrosion and mechanical wear, an important advantage in long-term water installations and radiator valve connections. With an overall length of 23.5 mm, the fitting remains discreet in confined spaces, yet provides enough thread engagement for a durable, serviceable joint.

This 3/8" x 1/4" brass reducer is a practical choice whenever a standard 1/2" to 3/8" valve adapter is not suitable and a more precise thread match is required, bringing order and reliability to both new installations and retrofit projects.
