Coupling Maintenance
Coupling Maintenance
The external threads identify male couplings. It is important that gaskets be placed in the female coupling so the connection between the couplings is watertight. Gaskets should be checked every time a connection is made, and be replaced if there are signs of wear, cuts, or if the gasket protrudes into the waterway. To facilitate making and breaking connections, (hooking hose together), couplings are furnished with rocker lugs. Rocker lugs are located on all male and female couplings with the exception of couplings found on booster hose. Booster hose couplings are equipped with small holes, which require a special spanner to tighten.
A new generation of quick connect couplings are being utilized on brush apparatus. The “Powerchk” couplings are slotted on both the male and female threads allowing both couplings to be instantly seated against the gasket. Also, the “Powerchk” coupling has two lugs as opposed to the standard three-lug coupling. In order to make or break the “Powerchk” coupling simply align the two lugs of the male coupling match up to the two lugs of the female coupling. When using the “Powerchk” coupling with a standard coupling, it is important to line up the higbee notches of opposing couplings.
All couplings are attached to the hose jacket by an expansion ring. This expansion ring is pressed outward, securing the hose jacket to the coupling.
STORZ COUPLINGS
Should be lubricated at least twice a year depending on usage. The dry silicone lubricant used will not be affected by heat or cold, nor attract dirt or sand.
The lug portion, the locks, and the raceway of the coupling should be lubricated.
Do NOT lubricate the gasket or seals.
THREADED COUPLINGS
The only maintenance required is to replace the gaskets periodically.
