We all know or should know what a nipple is (as it relates to our industry of course). A nipple is a short pipe typically with male threading at both ends to connect two other pipes or fittings. However, the size or type of nipple greatly depends on the application for which it is being used. It is important to get the proper nipple that is needed for the job. Three specific types of short or barrel nipples can confuse how to use them in their applications. In this article we will introduce you to, or familiarize you with; hex nipple or close nipple, hex plugs, and odd-length nipples.
The hex nipple typically has male threading on both ends of a hexagonal bolt shape in the center. This allows for easy torquing, tightening, or loosening using a wrench.
Hex nipples come in handy during applications that require you to connect two brass or steel pipes, both with female ends. Common applications involve automotive, plumbing, or industrial. You can also find these parts in HVAC systems as well.
Given the name, you may have figured out the purpose of a “Close Nipple.” The use of a close nipple allows you to create a closed, tight connection between two female-threaded steel pipes or fittings. Very little of this nipple is left exposed, making a complete seal.However, there is a downside to closed nipples. The only way to tighten or loosen a closed nipple is to grip the threaded portion with a wrench.
While it creates a tight closed seal, it becomes easy for the applicator to damage the threading, requiring the replacement of the nipple. Damaged threading can cause issues with your connection if not addressed. These issues may include leaking air, water, or other fluids depending on what application the nipple is being used for. There are special tools available to assist in their use!

Many Michigan cities are currently updating their old, or outdated plumbing systems. Cities such as; Flint, Ann Arbor, Saginaw, and Pontiac, MI are working to improve their old outdated plumbing or water systems. In dealing with these older systems, plumbers and technicians find many uses for odd-length and custom-size steel pipe fittings. Even if you don’t live in Michigan, we can help you. Historical buildings and other older building often need custom nipples to make sure everything is connected correctly.
In addition to the hex pipe nipple, the hex pipe plug is a very popular fitting. Hex pipe plugs are an important pipe fitting. Just like a hex pipe nipple, it has a hexagonal shape. It was made to stop the flow. Threaded at one end with the solid hex plug at the top makes it easy for a plumber to close and seal a pipe or tube connection. Gas instrumentation labs use these pipe fittings and plugs as well.

Black steel pipe nipples are made from carbon steel welded pipe that create a long lasting product with durability. The black nipples have practical applications jobs that deal with steam, natural gas, and oil. This is because of the fire and corrosion resistant materials they are made of. Corrosion can also be slowed by the schedule number of the pipe. With higher numbers, you will get a thicker pipe, which will affect the rate of corrosion.
For example in a steam pipe system schedule, 40 pipe is often used whereas a schedule 80 steel pipe will be used for a condensate pipe. Also, the reason for this is that the condensate is corrosive and thicker steel will provide a longer service life for the condensate pipe.
