What sizes of brass pipe fittings are available?

Hey there! I'm a supplier of brass pipe fittings, and I often get asked about the sizes available. So, I thought I'd write this blog to give you all the deets on the different sizes of brass pipe fittings you can get your hands on.

First off, let's talk about why brass is such a great material for pipe fittings. Brass is known for its durability, corrosion resistance, and malleability. It can withstand high temperatures and pressures, making it ideal for a wide range of applications, from plumbing in residential buildings to industrial piping systems.

Now, onto the sizes. Brass pipe fittings come in a variety of sizes to accommodate different pipe diameters and flow requirements. The most common sizing system for pipe fittings in the United States is the Nominal Pipe Size (NPS), which is a dimensionless number that roughly corresponds to the inside diameter of the pipe. However, the actual outside diameter of the pipe may vary depending on the pipe schedule (wall thickness).

Common Sizes

1/8 - inch and 1/4 - inch

These are some of the smallest sizes available. They're often used in applications where space is limited or where low flow rates are required. For example, they might be used in small - scale plumbing systems for appliances like coffee makers or in some types of pneumatic systems. If you're looking for small - sized brass pipe fittings like DOT Approved Pipe Long Street Ells in these sizes, you can check out DOT Approved Pipe Long Street Ells.

3/8 - inch and 1/2 - inch

These sizes are a bit more common in residential plumbing. They're suitable for supplying water to sinks, toilets, and other fixtures. You can use them for both hot and cold water lines. A lot of our customers use hex bushings in these sizes to connect pipes of different diameters. You can find a great selection of Hex Bushing in these sizes on our website.

3/4 - inch and 1 - inch

These are larger sizes that are typically used for main water supply lines in residential and small commercial buildings. They can handle higher flow rates, ensuring that there's enough water pressure throughout the building. Face bushings in these sizes are often used to make smooth transitions between pipes. Check out our Face Bushing options if you need fittings for these larger pipes.

Larger Sizes (1 1/4 - inch, 1 1/2 - inch, 2 - inch, etc.)

For industrial applications or large - scale commercial buildings, we offer even larger sizes of brass pipe fittings. These sizes are used in systems that require high - volume water flow, such as in factories, hotels, or large apartment complexes.

Specialty Sizes

In addition to the standard sizes, we also offer specialty sizes to meet the unique needs of our customers. Sometimes, a project might require a non - standard fitting size, and we're able to manufacture or source these for you. Whether it's a custom - sized elbow, tee, or coupling, we've got you covered.

Measuring and Selecting the Right Size

When it comes to choosing the right size of brass pipe fitting, it's crucial to measure the pipe accurately. You need to measure the outside diameter of the pipe, as the fitting needs to fit snugly over it. Using the wrong size fitting can lead to leaks, reduced flow rates, and other problems.

If you're not sure which size is right for your project, don't worry! Our team of experts is always here to help. We can guide you through the selection process, taking into account factors like the type of application, the flow rate requirements, and the pressure of the system.
