UPVC Female Adapter is a plug attached to a wire, cable, or piece of hardware and has one or more recessed holes with electrical terminals inside. It is designed so that a male connector with exposed conductors can be inserted snugly into it to ensure a solid physical and electrical connection.

A jack, outlet, or receptacle is another name for a UPVC Female Threaded Adapter (FAPT). The electrical conductors are not directly exposed when this type of connector is detached or removed. Therefore they are less prone to make unintended contact with exterior items or conductors.

A two- or three-prong electrical outlet, often known as a wall outlet, is the most common female connectors and fastners. Telephone jacks, headset jacks, coaxial cable chassis connections, and some D-shell connectors for computer serial and parallel ports are common types.
