1 Scope
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 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.
