    Abstract - (Show below) - (Hide below)

    Describes the characteristics of, and performance requirements for, the tube connector (compression) end(s) of twin ferrule connectors made of stainless steel.

    Scope - (Show below) - (Hide below)

    This British Standard specifies the characteristics of, and performance requirements for, the tube connector (compression) end(s) of twin ferrule connectors made of 316 stainless steel. It also specifies requirements for 316 stainless steel tubes.

    The twin ferrule connectors in this standard are suitable for use with annealed stainless steel tubes with outside diameters from 2 mm to 38 mm and 1/16 in to 2 in.

    This British Standard is applicable to twin ferrule connectors that are intended for the connection of plain end tubes to other tubes and to ports in accordance with BS EN ISO 6149-1, BS EN ISO 1179 and BS EN ISO 9974-1, and other ports agreed between the purchaser and manufacturer. It provides external envelope, tube-end-to-tube-end and tube-end-to-port dimensions that facilitate designing systems that use twin ferrule connectors.

    NOTE These twin ferrule connectors can also be used with other austenitic stainless steel tubes, typically 304, 316L, 321, etc.
