  • Front
  • Back

A flexible, portable tube manufactured from watertight materials in 50-100 foot lengths that is used to transport water from a source or pump to the point where it is discharged to extinguish fire

Fire Hose

Hose that is designed for the purpose of moving water between a water source and a pump that is supplying attack hoselines or fire suppression systems

Supply Hose

Hose that is used by trained firefighters to combat fires

Attack Hose

Point at which the fire department can connect into a sprinkler or standpipe system to boost the water flow in the system


Fire Department Connection

Large diameter, collapsible piece of hose used to connect a fire pump to a pressurized water supply source; sometimes incorrectly referred to as "soft suction hose"

Soft Sleeve Hose

Intake hose that connects pumping apparatus or portable pump to a water source

Suction Hose

Rigid, non-collapsible hose that operate under vacuum conditions without collapsing, allowing a pumping apparatus or portable pump to draft water from a static source

Hard-Suction Hose

Male or female coupling with a spiral thread

Threaded Coupling

Coupling with no distinct male or female components

Non-Threaded Coupling

AKA Storz Coupling/Sexless Coupling

Portion of a coupling that serves as a point of attachment to the hose


Special cut at the beginning of the thread on a hose coupling that provides positive identification of the first thread to eliminate cross-threading

Higbee Cut

Notches or grooves cut into coupling lugs to identify by touch or sight the exact location of the Higbee Cut

Higbee Indicators

Non-threaded (sexless) coupling with two hook-like lugs that slip over a ring on the opposite coupling and then rotate 90 degrees clockwise to lock

Quarter-Turn Coupling

Non-threaded (sexless) coupling commonly found on LDH. Non-threaded fire hose couplings have been used in the North American fire and emergency services since the early 1900's. With this type of coupling, the mating of two couplings is achieved with locks or cams without the use of screw threads

Storz Coupling

Small tool primarily used to tighten or loosen couplings; can also be used as a prying tool or a gas key

Spanner Wrench

Hose appliance with one female inlet and multiple male outlets, usually smaller than the inlet. Outlets are usually gated


Hose appliance used to combine two or more hoselines into one. Has multiple female inlets and a single male outlet


Any variety of hose appliances with one female inlet for 2 1/2 inch hose or larger and with three gated outlets, usually two 1 1/2 inch and one 2 1/2 inch

Water Thief

Device for connecting hose couplings with dissimilar threads but with the same inside diameter


Device that facilitates the connection of hoselines to provide an uninterrupted flow of extinguishing agent


Fitting used to attach a smaller hose to a larger hose. The female end has the larger threads, while the male end has the smaller threads


Specially designed tool used to open or close hydrants and to remove hydrant caps

Hydrant Wrench

Main hose carrying area of a pumper or other apparatus designed for carrying hose

Hose Bed

Arrangement of hose usually placed on top of a hose load and connected to the end of the load


Arrangement of fire hose in a hose bed or compartment in which the fire hose lies flat with successive layers one upon the other

Flat Load

Arrangement of fire hose in a hose bed or compartment in which the hose lies on edge with the folds adjacent to each other

Accordion Load

Arrangement of fire hose in a hose bed or compartment in which the hose lies on edge in the form of a horseshoe

Horseshoe Load

Extra fold placed along the length of a section of hose as it is loaded so that its coupling rests in proper position


Attack hose connected to a discharge when the hose is loaded; this shortens the time it takes to deploy the hose for fire fighting


Non-collapsible rubber-covered, rubber-lined hose usually wound on a reel and mounted somewhere on the apparatus and used for extinguishment of incipient and smoldering fires

Booster Hoseline

Hose appliance that is attached to the hydrant to permit additional supply hoses to be attached without interrupting the flow of water

Four-way Hydrant Valve

The end of a charged hoseline that is flowing water without a nozzle or valve to control the flow

Open Butt

Occurs when contact with an object or surface causes slices, rips, and abrasions on the exterior covering, crushed or damaged couplings, and cracked inner linings

Mechanical Damage

Can result from exposure to excess heat or cold temperatures

Thermal Damage

Caused when hose with woven-jacket of cotton or other natural fiber is stored wet

Organic Damage

Caused by exposure to petroleum products, paints, acids, or alkalis weakening the hose to the point of bursting under pressure

Chemical Damage

Chemical process in which metal is attacked by some substance in the environment and is converted to an unwanted compound that gradually weakens or destroys metal


Can cause deterioration and cracking between folds; may occur if hose is left hanging in tower for excessive periods of time

Age Deterioration

Used in pumper discharged and gated wyes

Ball Valves

Used to control flow from hydrant

Gate Valves

Incorporate flat baffle that turns 90 degrees

Butterfly Valves

Used in Siamese appliances and FDC to allow water to flow in one direction only

Clapper Valves

Protects hose from mechanical damage of dragging over sharp corners

Hose Roller

Can be installed when hoseline ruptures but must remain charged to continue the fire attack

Hose Jacket

Can be used to stop the flow of water in a hoseline for various reasons

Hose Clamp

Tightens or loosens couplings; has a number of other features built in

Spanner Wrench

Used to remove discharge caps from fir hydrant outlets and to open fire hydrant valves

Hydrant Wrench

Sometimes used to strike lugs to tighten or loosen intake hose couplings

Rubber Mallet

Help prevent damage to fire hose when vehicles must drive over it

Hose Bridge or Ramp

Device used to protect fire hose from vibrating and rubbing against other surfaces

Chafing Block

Used to carry, pull, or handle charged hoselines

Hose Strap, Hose Rope, and Hose Chain

Very weak and only found on occupant use fire hose. They often crack if reattachment to the hose is attempted

Cast Couplings

Usually made of aluminum or aluminum alloy, allowing for their lightweight and high strength. They are somewhat stronger than cast couplings

Extruded Couplings

Made of brass or other malleable metal and are the strongest and most expensive

Drop Forged Couplings

Series of tests performed on apparatus and equipment in order to ensure operational readiness of the unit. These tests should be performed at least yearly or whenever a piece of apparatus or equipment has undergone extensive repairs

Service Test
