11 Brass Fitting Types and How They Work

Brass Fitting Types

Brass is one of the preferred materials for fittings, mainly due to its superior qualities, which range from durability and corrosion resistance to aesthetics. Different brass fitting types are also available for use by plumbers and construction experts. This article provides an overview of these types of brass fittings, including their features and specific applications.

Brass Fittings

Let’s begin by understanding brass fittings. These are fittings made from brass, an alloy made by mixing copper and zinc. Brass fittings are hardly mistakable with their characteristic yellow or golden colors, making them visually appealing.

Brass fittings can be entirely brass or combine brass and plastic parts, sometimes brass and rubber. Available in a broad range of sizes and configurations, they’re useful in many different domestic and industrial applications. Let’s see some of these uses.

What are Brass Fittings Used For?

The use of brass fittings cuts across different industries: brass fitting for water lines (both residential and commercial), brass fittings for gas, brass fittings for maritime applications, and brass fittings for automotive and HVAC systems. In these different uses, the parts may serve these functions:

  • Redirect the flow of a liquid or gas
  • Control or regulate flow
  • Connect two pipes together
  • Act as On/off valves
  • As pressure relief valves
  • For drain pipes

Brass Fittings Types

As mentioned, brass fitting manufacturers make the product in many different designs. As a result, it’s available in various configurations, each serving a specific purpose when installed. Here below is a list of the most common brass fitting types today.

① Brass Compression Fittings

Brass Compression Fittings

The above image shows these fittings comprise a compression nut and sleeve. The purpose of the two components is to press against each other when installed, creating a leak-free connection. Compression brass fittings are suitable for water lines. They are sold in various configurations, from elbows and adapters to tees. You can use them to connect copper, aluminum, or plastic pipes.

② Brass T Fitting

Brass T Fitting

  Brass T, or brass tee fittings, as their name implies, form a T shape consisting of three ends. This design allows you to split a line into two or merge two lines into one. These brass fitting types are designed in different sizes for use in different applications and can be threaded or welded types. Their applications range from irrigation to HVAC or home heating systems

③ Brass Union Fitting

Brass Union Fitting

A brass union fitting allows you to link or join pipes. More importantly, it will enable you to disconnect these pipes without cutting them since they use a separation ring to produce a temporary connection. This allows easier repair and deconstruction. These brass fitting types are common in the following installations: gas piping, Marine networks, and hydraulic systems.

④ Brass Adapter Fittings

Brass Adapter Fittings

These fittings are helpful when you want to connect two different pipes. These can be pipes that have varying diameters that make them incompatible. The fitting lets you do that by altering the pipe end. Brass adapter fittings can be slip-on or threaded, built in different shapes and sizes. Their most common applications are water lines, such as filtration and sprinkler pipes.

⑤ Brass Y Fitting

Brass Y Fitting

A brass wye fitting is a fitting that feature a Y design. Ideally, it splits your single flow line into two. It finds application in systems where gases or liquids are to be sent in two different ways from a single line. Such application cases include venting pipes, gas pipes, and sewage lines.

⑥ Brass Coupling Fitting

Brass Coupling Fitting

A brass coupling fitting is used to join or connect two types, providing a smooth flow of a fluid, whether gas or liquid. Unlike unions, they form lasting connections that will not need to be taken apart. These fittings can, depending on their required results, allow you to connect pipes of similar or different diameters since they come in many different sizes.

⑦ Elbow Brass Fitting

Elbow Brass Fitting

An elbow brass fitting is a type of fitting that is used to change a plumbing’s direction, with the aim of either redirecting the flow or allowing pipes to avoid obstacles located within the plumbing network. Available in different angles that vary from 45° to 90°, elbow fittings mostly find application in general plumbing lines and drainage pipes.

⑧ Brass Nipple Fitting

Brass Nipple Fitting

A brass nipple fitting is used when two female ends of a piping system need to be joined together. It comes with male threads on either end, forming a tight connection between the two pipes or between a pipe and fitting. Like any other brass fittings, these are sold in various sizes to suit varied application needs.

⑨ Brass Cap Fitting

Brass Cap Fitting

A cap is a type of fitting that goes over the end of a pipe to seal it, especially if it will not connect to another. These types of brass fittings, in addition to providing a simple way to seal pipes, are designed to install in different ways. So they can be threaded fittings or the type that is to be glued or soldered to the pipe.

⑩ Brass Plug Fittings

Brass Plug Fittings

Unlike caps, brass plug fittings function as temporary seals to pipes, and are commonly used when piping systems have to be blocked for maintenance. They also go into the pipe and not over it like caps do. These brass fittings are available in many different design features including hex, countersunk, and square hex.

⑪ Brass Valve Fittings

Brass Valve Fittings

Brass valves are used in fluid control and plumbing systems. They help regulate the flow of fluids such as liquids and gases, and connect to other fittings and pipes. Brass valve fittings are durable, safe to use with both potable and non-potable water, and resistant to the corrosion that different materials would cause. Just like the valves of any other material, they can be different types.

Conclusion

Brass fittings are versatile products that last a long time and resist corrosion, among other characteristics. The brass fitting types in this article are the most common and what you’re likely to use in applications that range from residential to commercial or industrial. That includes when you want to control the flow of a fluid, change its direction, and so on.
