A press-fit brass elbow is an important fitting used in plumbing systems to connect two pipes at an angle, usually 90 degrees, while ensuring a secure and leak-resistant joint. Its structure is composed of several components that work together to provide durability and ease of installation.

The main part is the brass body, which forms the core of the fitting. Brass is commonly used because of its strength, corrosion resistance, and ability to withstand both hot and cold water applications. The elbow shape allows pipes to be redirected without the need for complex installations.

Around the ends of the brass body are press sleeves, usually made of stainless steel. These sleeves are designed to be crimped or pressed using a specialized tool, which locks the pipe into place and creates a permanent, tight connection.

Inside the fitting, there is typically an O-ring seal, often made from elastomeric materials. The O-ring plays a crucial role in preventing leaks by creating a watertight seal between the pipe and the brass body once the press sleeve is secured.

Some press-fit brass elbows also include plastic separation rings or insulating elements. These components help maintain correct positioning of the O-ring and can reduce direct contact between different materials, which supports long-term reliability.
