One-Piece Coupling is typically refers to a type of coupling or connector designed as a single, integrated unit without multiple separate components. These couplings are often used in various applications to connect, join, or secure two pieces or parts together.

One-piece couplings are designed for simplicity and ease of use. They typically do not require the assembly of multiple parts, making them convenient for quick connections.

Many one-piece couplings are constructed from durable materials such as metal or high-quality plastic to ensure strength and longevity.
