Cylinder Manifold Hose

Hose Guide

600mm with 5/8Ó BSP cylinder connector to 3/8Ó BSP manifold connector is suitable for nitrogen, argon, hydrogen, helium, carbon dioxide, etc.

The same assembly but at 900mm length would suit oxygen and oxygen mixtures (e.g. carbogen). We would recommend that a heat sink be fitted to the hose and, obviously, the hose has got to be cleaned to oxygen standard.

As you will, no doubt, be aware, the high pressure flexible hoses ('pigtails') that are used to connect gas cylinders to your manifolds should be routinely replaced every 5 years (non-metallic) and possibly more frequently (~annually) in the case of metallic 'pigtails' used for oxygen due to work hardening and cracking problems.

For some time we have recommended that such [high pressure] flexible hoses be fitted with an 'anti-whip' cable in accordance with BS EN ISO 14113. Clearly, the purpose of the anti-whip cable is to minimise the extent of personal injury occurring in the event of one of these lines bursting. An example of such a hose is shown here:

These parts are available in 4 standard lengths: 600mm, 900mm, 1,800mm and 3,500mm.

However, for most typical manifold applications, the 600mm and 900mm lengths would be most appropriate ( the longer hoses are mainly used for connecting cylinder packs to manifolds).
