What Is NPT Hex Nipple?

NPT Hex Nipple refers to a type of pipe fitting used for connecting and extending pipe sections with male NPT (National Pipe Thread) ends. It is called a "hex" nipple because it has a hexagonal shape in the middle, allowing for easy tightening or loosening using a wrench.

Here are some key features and characteristics of an NPT Hex Nipple:

1. NPT Threads: NPT is a tapered thread standard used for pipe fittings in the United States. NPT threads create a tight seal by wedging the threads together. NPT Hex Nipples typically have male NPT threads on both ends, allowing them to be used as connectors between two female-threaded pipes or fittings.

2. Hexagonal Shape: The hexagonal shape in the middle of the nipple provides a convenient gripping surface for tightening or loosening with a wrench or other tools. The flat sides of the hex shape prevent the nipple from rotating while tightening or loosening, ensuring a secure connection.

3. Versatile Connection: NPT Hex Nipples can be used in various applications where a male-to-male connection is needed, such as joining two lengths of pipe, connecting different types of pipe fittings, or adapting pipe sizes. They are commonly used in plumbing, HVAC systems, hydraulic systems, and other industrial applications.

4. Material and Finish: NPT Hex Nipples are typically made from materials such as brass, stainless steel, or carbon steel. The choice of material depends on the application's requirements, including factors like pressure rating, chemical compatibility, and environmental conditions. They may also have different surface finishes, such as plain, nickel-plated, or galvanized, to enhance corrosion resistance or aesthetic appeal.

It's important to ensure that the NPT Hex Nipple is properly sized and matched with the corresponding pipe or fitting to ensure a secure and leak-free connection. The size and thread type should be selected based on the specific requirements of the piping system.
