Fittings are designed to join, redirect, or terminate pipes and hoses in a system. They come in a range of shapes, such as elbows, tees, couplings, and reducers, allowing for flexible configuration of pipelines to meet specific operational needs. Made from materials like metal, plastic, or rubber, fittings are engineered to withstand pressure and temperature variations, ensuring a secure and leak-proof connection.

Adapters, on the other hand, are used to connect pipes or hoses of different sizes, types, or materials. They serve as transitional components that enable compatibility between dissimilar parts of a system, such as connecting a metal pipe to a plastic hose. Adapters are crucial for modifying systems to accommodate different standards or specifications, thereby enhancing system versatility and functionality.
