What is the difference between barrel nipples and hex nipples?

Both barrel nipples and hex nipples are one of many tools in a contractor’s arsenal. However, due to the vast amount of variety and applications, sometimes these devices can be confused between each other, and which is best used when.

At Anglo Stainless, we supply a vast amount of both appliances, and with such an extensive selection to choose from, making sure you have the right tool for the job is essential.

In this blog, we will be breaking down the difference between barrel nipples and hex nipples and which applications they are best suited for.

Barrel Nipples

Barrel nipples, also known as pipe nipples, are cylindrical fittings with male threads on both ends.

They are typically made from brass, stainless steel, or other materials suitable for plumbing applications. The term ‘barrel’ refers to their cylindrical shape, resembling a small barrel or tube.

Application

Barrel nipples are commonly used in plumbing systems to extend or connect pipes, fittings, valves, or equipment.

They are versatile fittings that can be employed in various industrial, commercial, and residential settings.

Hex Nipples

Hex nipples, also known as hexagon nipples, are fittings with male threads on both ends, similar to barrel nipples.

The distinguishing feature of hex nipples lies in their shape. As the name suggests, hex nipples have a hexagonal shape at the centre, providing a hexagonal surface for easy gripping.

Application

Hex nipples are commonly used in plumbing and fluid transfer systems where a secure and tight connection is required.

Their hexagonal shape makes them ideal for applications that involve frequent disassembly and reassembly, as they offer increased grip and torque.

When to choose a Barrel Nipple or Hex Nipple

The primary distinction between barrel nipples and hex nipples lies in their shape.

Barrel nipples have a smooth cylindrical design throughout their length, while hex nipples have a hexagonal shape in the middle, providing an advantageous gripping surface.

Selecting the appropriate fitting depends on the specific requirements of your plumbing or pipe system. Consider factors such as the desired level of grip, ease of installation, and nature of the application.

If a secure grip and easy tightening are essential, a hex nipple may be the ideal choice. Additionally, if a smooth flow path and length customization are more critical, a barrel nipple may be more suitable.
