Nozzle tubes and fittings
Poor seals are usually caused by:
• Missing O-rings or gaskets
• Damaged or incorrectly seated O-rings
• Dry or deformed O-rings or gaskets
• Foreign bodies
In case of leaks:
DO NOT overtighten. Disas-
semble, check condition and
position of O-ring or gasket.
Clean, lubricate and reassemble.
The O-ring must be lubricated
ALL THE WAY ROUND before
fitting on to the nozzle tube. Use
non-mineral lubricant.
For RADIAL connections only hand-tighten them.
For AXIAL connections, a little mechanical leverage may
be used.
