6-2.6 Hose Lines and Appurtenances
a.
Hoselines proper do not require any lubrication.
b.
Attached appurtenances should be lubricated as follows on a routine basis.
"W"
1. Lubricate pivot points on quick disconnect camlock couplings with a light oil routinely. See Fig. 6-1.
"V"
2. Repack 6-inch hose swivels with lubricant when evidence of too much tightness (resistance to rotation) exists.
See Fig. 6-9.
"W"
3. Lubricate pivot points on grooved coupling clamps with a light oil. See Fig. 6-11 and 6-12.
6-2.7 Aluminum Pipe and Fittings
a. No lubrication of aluminum pipe per se is required.
"W"
b. Single groove and double grooved coupling clamp pivot points should be lubricated with a light oil routinely.
See Fig. 6-11 and Fig. 6-12.
6-2.8 Valves
"W"
a. Aluminum Gate Valves.
Clean and lubricate the valve stems. Do this when the valve is open. Use a film of light oil which will not harden and will
lubricate the packing as valve is operated. Never use grease. It will harden and collect dirt. See Fig. 6-19.
"W"
b. Ball and Needle Valves.
No lubrication other than that provided by the stem packing is required. The packing should be replaced when it is too
compressed to lubricate the valve adequately and when tightening the packing nut no longer stops a leak around the
valve stem. See Fig. 6-20 and 6-21.
"D"
c. Fueling Nozzles.
Lubricate pivot points and sliding surfaces lightly once per day to minimize wear. See Fig. 6-18.
6-2.9 Meter Strainer Assemblies
a. No routine lubrication is required for either the meter or the strainer
"V"
b. When a strainer is opened, it is recommended that the closure (head) face be lubricated lightly, after cleaning,
before it is replaced. See Fig. 6-23.
6-2.10 Bare Metal Surfaces
"V" It is recommended that any bare ferrous metal surface be lubricated by brushing or spraying on a medium grade oil
to minimize corrosion. If the surface is not a sliding surface, it is preferrable that it be cleaned and painted.
