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.

POWERCHK COUPLINGS
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.

At Pumpkin Center VFD, we strive to give our members quality equipment to use at all times. We’ve found over the years that small details make huge differences. Our equipment committee is always asking the question “Is something better out there?” We stay abreast of current industry trends and investigate the latest and greatest from equipment manufacturers to make sure our guys and girls have what they need to do the job and do it well. In 2009 we were tired of the fire hose we had been purchasing and bought some Niedner XL-800. The hose is still in service today. During this time we’ve found that in addition to being durable, it rolls up extremely tightly, packs tightly in hose beds and is lightweight, which lessens fatigue on members. With a comparable friction loss rate to much other hose in the industry, our committee has yet to find a reason to leave Niedner. We had several sections of cloth Niedner 4 inch supply hose before switching to 5 inch as well. It was the best supply hose I’ve ever seen or used.
