NFPA 1963
The standard of fire couplings
Supply hose
From water source to apparatus
Attack hose
Transports water at increased pressure from apparatus to nozzle
Wet racking hose
Mould resistant
Draft hose
Lightweight and large
Wild fire hose
Self sweating for Ash
Male couplings
Expose threads
Female
Internal threats
High bee notch
Threaded firehose couplings are equipped with these notches or indicators to prevent cross threading
Nonthread coupling
Uses locks or cams rather than screws
Example, sortz couplings / wildland, quarter turn
Advantages of non-threaded
Sexless
Eliminate cross, threading
Cut down on adaptors
Disadvantages of non-threaded
Can be easily be disconnected
Can bind
Fire hose services in service
Annually
After being frozen
Attachment of a new coupling
New house
Services of fire hoses on racks
Every year
After any damage
Hard section hoses must be pressurized
And dry vacuum tested
Double male adaptor
Used to connect to female couplings of the same diameter and thread
Double female adapter
Used to connect to Male couplings of the same diameter and thread
Reducer
Connects two hoses of different diameters
Most common size is being 100 MM»_space; 65mm
65mm»38mm
Wye
Divide one hose into two or more
One female to two males
Gated
Handles to be shut off switches
Siamese
Two or more hose lines brought into one hose line
Two or more females into one male
Hydrant gate
Must be connected to the hydrant before opening
Saves you having to shut the second hose attachment
Drain valves
Relieves pressure
Drains unused lines
How to clean
Simply clean with warm, soapy, water, and bristle brush
