10 Different Types of Nipples for Pipe Fittings

When it comes to pipe fittings, nipples play a crucial role in connecting and extending pipelines. Nipples are short pieces of pipe with male threads at each end, designed to join or extend various sections of piping. They come in a multitude of types, each tailored to specific applications.

10 Types of Pipe Fitting Nipples

  1. Extension Nipples: Extension nipples are precisely what the name suggests - they extend the length of a pipe. They have male threads at both ends and are typically used to add length to existing pipes. These nipples come in various lengths, allowing for customization to fit the required extension.
  2. Hexagon or Hex Nipples: Hex nipples, also known as hexagon nipples, are distinguished by their hexagonal section in the middle. This design serves a dual purpose: it provides a gripping surface for wrenches during installation, and it allows for better flow control. Hex nipples are commonly used in applications where a tighter seal and flow adjustment are necessary.
  3. Close Nipples: Close nipples have male threads at both ends and are very short in length. They are ideal for joining two female-threaded fittings that are extremely close together. These nipples eliminate the need for a longer piece of pipe, providing a compact and efficient connection.
  4. Welded Nipples: Welded nipples, as the name implies, are designed for welding onto pipes. They have male threads at one end and a plain end for welding at the other. These nipples are commonly used in industrial settings where pipes need to be securely joined through welding.
  5. Swage Nipples: Swage nipples are used to connect pipes of different sizes. They have different-sized male threads at each end, allowing for a seamless transition between pipes with varying diameters. Swage nipples are especially useful when a reduction in pipe size is required.
  6. Barrel Nipples: Barrel nipples, also known as close nipple or pipe nipples, have male threads at both ends and are typically equal in length. They are used for short extensions and are often employed in low-pressure applications.
  7. PEX Nipples: PEX nipples are specifically designed for cross-linked polyethylene (PEX) piping systems. They have PEX-compatible ends that can be easily connected to PEX pipes without the need for soldering or threading. PEX nipples are commonly used in residential plumbing systems.
  8. Stainless Steel Nipples: Stainless steel nipples are known for their corrosion resistance and durability. They are suitable for a wide range of applications, including water, gas, and oil pipelines. These nipples are often used in environments where rust and corrosion are a concern.
  9. Brass Nipples: Brass nipples offer excellent resistance to corrosion and high temperatures, making them suitable for a variety of applications. They are commonly used in plumbing systems, water heaters, and industrial settings.
  10. PVC Nipples: PVC nipples are designed for use in PVC piping systems. They are lightweight, easy to install, and corrosion-resistant. PVC nipples are frequently used in irrigation, drainage, and other applications involving PVC pipes.
