Nozzle Pipe Assembly
If leaks of fluid 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 sealings 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 overtighten 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.
How To Disassemble Pipe Fittings
Pipe fittings assembled.
Unscrew the connector (A) on the steel pipe.
Pull the nozzle pipe (B) away from the T-piece (C).
A lock ring (D) and an O-ring (E) is located at the end of the pipe.
The O-ring can now be removed from the pipe for maintenance.
How To Reassemble Pipe Fittings
To reassemble the fittings, place the connector, lock ring and O-ring on
the pipe in that order. Tighten the connector onto the T-piece.
