Are you looking for an answer to the topic “How do you measure a fire hose nozzle?“? We answer all your questions at the website Chiangmaiplaces.net in category: +100 Marketing Blog Post Topics & Ideas. You will find the answer right below.
Inside Diameter – 1-3/4″ Inches. Lay Flat Width – About 3-1/4″ Inches. Length – 50 Feet / 75 Feet / 100 Feet. Couplings – Choose 1.5″ NH/NST (Fire Hose Threads) or 1.5″ NPSH (Straight Pipe Threads) Hardcoat Anodized Aluminum T-6061.The standard three sizes of hose lines are 1½, 1¾ and 2½ inch. Depending on the size and severity of the fire, hose line requirements vary to get the job done efficiently. Selecting the incorrect one from the start can cause delays in fire suppression and exhaustion.
- Check the female coupling for numbers like 1.5 or 2.5.
- Measure the inside diameter of the male coupling. Do not measure the female coupling.
- Check for numbers stenciled on the hoses.
- Do not measure the hose laying flat.

What is the standard size of fire hose?
The standard three sizes of hose lines are 1½, 1¾ and 2½ inch. Depending on the size and severity of the fire, hose line requirements vary to get the job done efficiently. Selecting the incorrect one from the start can cause delays in fire suppression and exhaustion.
How do you measure a hose connector?
Using a ruler or vernier, measure across the outside diameter of a male or hose tailpiece thread or measure the inside diameter of a female thread. If the thread measures 0.5″ it is not a 1/2″ BSP thread.
Is fire hose measured from the inside or outside diameter?
On straight threaded hose couplings, measure the “Outside Diameter of the Male” (ODM) or the “Inside Diameter of the Female” (IDF) from peak-to-peak of the threads.
How many types of fire nozzles are there?
The two main fire hose nozzle types we offer are deluge tip and smooth bore tip, but there are also economy, forestry, municipal, and Coast Guard-approved fire hose nozzles.

What is the NFPA Standard for fire hose?
NFPA 1962: Standard for the Care, Use, Inspection, Service Testing, and Replacement of Fire Hose, Couplings, Nozzles, and Fire Hose Appliances.
How much water does a 1 3 4 fire hose flow?
In real life, an 1-3/4” handline can comfortably and safely flow from 100 to 180-GPM on the fireground, and any flows over 150-GPM are best run through low pressure combination or smooth bore nozzles to reduce nozzle reaction forces.
What is the normal pressure head in the nozzle of the fire hose?
In order for a conventional nozzle with a fixed opening to operate at the correct nozzle pressure of 100 psi, the proper gpm flow must be supplied. For example, a selectable gallonage nozzle with settings of 30, 60, 95 and 125 gpm will only deliver those flows of 100 psi of nozzle pressure.
What is Type 2 fire hose?
The Elite type 2 layflat fire hose is principally used by Municipal and Industrial fire brigades. However it is a multipurpose hose also commonly used within the shipboard and marine industry, on refineries and construction sites, in agriculture and irrigation, general industrial use and for all wash-down applications.
How do I know what size hose bib I have?
The outlet of your hose bib likely matches the size of the water pipes inside your home. Pipes that are 3/4 inch have greater water pressure than those that are only 1/2 inch wide. So, if you want good water pressure coming out of your garden hose, you should go with a 3/4-inch hose bib.
How do you measure couplings?
For the female part of the coupling, (also known as the coupler) the size is obtained by measuring the diameter of the open end, or inside diameter (ID). For the male part of the coupling (adapter), the size is obtained by measuring the diameter of the adapter end, or outside diameter (OD).
What are the three diameters of fire hoses most commonly found on ships?
6. Fire Hose and Nozzles: Fire hoses with a length of at least 10 meters are used in ships. The number and diameter of the hoses are determined by the classification society. The nozzle of diameters 12 m, 16 m and 19 m used on the ship are of dual-purpose types- Jet and spray mode.

What psi are fire hoses?
The usual working pressure of a firehose can vary between 8 and 20 bar (800 and 2,000 kPa; 116 and 290 psi) while per the NFPA 1961 Fire Hose Standard, its bursting pressure is in excess of 110 bar.
What is the cone setting on a hose for?
Cone: The cone setting gives you a circle of spray so that you can water a ring of plants all at once. Jet: The powerful jet spray pattern will damage plants, but it is a great setting for powering dirt and debris from walkways, driveways, and patio furniture.
