BS 5682 Medical Gas Outlets – British Standard Terminal Units

A BS 5682 medical gas outlet accepts the British standard probe used across the United Kingdom, the Gulf, much of Africa and South Asia. Mechanically it is the same Tecnomed terminal unit as the DIN version: a calibrated brass lower body, a gas-specific separator housing and an upper head that carries the socket. The probe is retained by four stainless-steel pins, connects with no more than 100 N and releases at 110 N, so equipment can be changed over quickly at the bedside.

Gas is interrupted by a check valve whenever the upper body is taken off, which keeps routine head maintenance out of the shutdown plan. Every gas-wetted part is brass, degreased for medical use; the MC model adds a brass upper body and the PC model an ABS plastic cover over the same block. The separator housing is nickel-free chrome-plated brass, the body-to-head joint is sealed with a gasket and all internal seals are silicone.

Ordering follows the same logic as the rest of TEC61: connection codes 05 to 08 identify the 45° pipe, 90° pipe, 45° union and rear outlet versions, and the .MC or .PC suffix fixes the cover material. Copper tails are 8 mm by 120 mm as standard, with 10 mm and 12 mm optional, and are plugged after degreasing. The same BS 5682 socket is also the basis of the Eva and Mega series and of the BS terminal wall boxes.
