Detailed Description

Reducing adapters Female to Male NPT are used to connect pipes or instrumentation lines of different diameters in oil and gas systems. They allow a larger pipe or fitting to join with a smaller one without leaking, ensuring the flow of liquids or gases remains safe and controlled. These fittings are especially useful in situations where space is limited or existing piping needs to be adapted to new equipment.

They are made from high-quality materials such as stainless steel, brass, or carbon steel, which can handle pressures up to 10,000 PSI. The female NPT side threads internally to receive a male pipe, while the male NPT side threads externally to connect to a female fitting. This combination provides a secure, leak-resistant connection that is durable even under high pressure, vibration, or temperature changes.

Reducing adapters are widely used in oil and gas production, processing, and distribution systems.

They are ideal for connecting instrumentation, control systems, chemical injection lines, or any piping where size changes are required. Their compact design and simple installation make them a practical choice for engineers and technicians who need reliable connections in complex piping networks.
