Brass tee fittings come in a variety of sizes and configurations to accommodate different piping systems and applications. These fittings are designed to provide a convenient way to split or divert the flow of fluids or gases in plumbing, heating, cooling, and other systems.

In terms of sizes, brass tee fittings are available in a range of dimensions to match the diameter of the pipes they are intended to connect. Common sizes include 1/4 inch, 1/2 inch, 3/4 inch, 1 inch, and larger, with variations in between to suit specific requirements. The size of the tee fitting must match the size of the pipes it is connecting to ensure a proper fit and reliable performance.

Brass tee fittings come in various configurations to accommodate different piping layouts and connection types. These configurations include:

1. Equal Tee: A tee fitting where all three openings are the same size, allowing for an equal split in the flow of fluids or gases.

2. Unequal Tee: A tee fitting with one or more openings of a different size, enabling the flow to be divided unequally or to accommodate pipes of different diameters.

3. Female Tee: A tee fitting with female threads on all three openings, allowing for connection to pipes or fittings with male threads.

4. Male Tee: A tee fitting with male threads on all three openings, suitable for connecting to pipes or fittings with female threads.

5. Compression Tee: A tee fitting designed for use with compression fittings, featuring compression sleeves or ferrules to create a leak-proof seal when tightened onto the pipes.

These different sizes and configurations of brass tee fittings provide flexibility and versatility in designing and constructing piping systems for various applications, ensuring compatibility and efficient fluid or gas flow management.
