Joints and Joint Faces

Remove all traces of old jointing materials prior to reassembly. Inspect joint faces for scratches or burrs and remove with a fine file or oilstone; do not allow swan' or dirt to enter tapped holes or enclosed parts. Blow out any pipes, channels or crevices with compressed air, refitting or renewing any O-rings or seals which have been displaced by the compressed air.

Always use the specified gaskets. Use jointing compound only when recommended, otherwise fit joints dry. When jointing compound is used, apply in a thin film to metal surfaces; take great care to prevent it from entering oilways, pipes or blind tapped holes.
