    When in the shop, I asked about the use of polytetrafluoroethylene
    (ptfe) tape as such things were once recommended (although I don't
    remember exactly what pipes they used to be recommended for - perhaps
    household gas plumbing) and they said that ptfe tape should
    definitely NOT be used for oxygen pipe joints as the ptfe contains
    oil and the oxygen in the pipes will (or is likely to) react
    explosively if the tape is used. They do NOT recommend its use for
    any of the fuel gases either. The chap said that the modern fittings
    are designed to be gas tight when tightened correctly. Presumably
    they use some sort of compression fittings with collapsible olives
    or the like in the UK.
