Nozzle Pipe Assembly
If fluid leaks occur in the pipelines on the spray boom, it is necessary to check the gaskets. The pipe fittings need to be
disassembled to locate the gaskets. Occasional maintenance of the gaskets and pipe assemblies is recommended.
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 objects.
In Case of Leaks
DO NOT over-tighten the pipe fitting. Follow this procedure instead:
1.
Disassemble the pipe fitting.
2.
Check condition and position of O-ring or gasket. Replace it if damaged or cracked.
3.
Clean and lubricate the O-ring or gasket. Lubricate all the way around using a non-mineral lubricant.
4.
Reassemble the O-ring or gasket and pipe fittings. When tightening the fittings, a little mechanical leverage may be
used.
