Commercial hoses quotation/request form
There are 4 main questions we will need to ask when contacting us for a quotation comcerning your fire hoses and connectors to be able to quote effectively.
Hose type
We can offer 3 different types of Layflat Fire Hose.
- Type 1 (Starflex Uncoated)
- Type 2 (Starflex Coated)
- Type 3 (Nova)
all have a rubber inner lining.
Type 1 and 2 are a canvas type hose which is used on occasions or low use.
Type 3 Hose is premium hose which has a PVC outer jacket rather than a canvas jacket. This make it more hard wearing and is resistant to oil etc (see data sheets). The Type 3 Nova hose is used by professional Fire Fighters.

Hose length
The hoses come in standard length which are 15mtrs, 18mtrs, 20mtrs, 23mtrs, 25mtrs, 30mtrs and 60mtrs.
Diameter
The hose diameter can come in the following sizes: 38mm (1.5”), 45mm (1.75”), 52mm (2”), 64mm (2.5”) and 70mm (2.75”). Other sizes are available but not as common 25mm (1”), 76mm (3”) etc.
Sometimes the diameter is dictated by the couplings as they will only come with a set size tail. Eg. The biggest tail on a Nakajima 50A will be 52mm (2”) therefore 2” hose will be needed to use this coupling.
A common problem is that people measure the hose flat and think this is the diameter, but is not the case. Click on the PDF datasheet below to work out the size.

Couplings
Couplings are an important part of the fire hose as different vessels have different types and sizes. It is important to identify the correct type and size. (See attached a Characteristic sheet to help identify the main differences between each type).
The couplings are available in both light alloy or Gunmetal/Brass however most marine customers will want the Gunmetal/Brass couplings as this is more suited to the salt water and harsh environment were as Light Alloy will corrode in time.
Couplings are generally wired on to the hose as per the BS 6391:2009 Standard. This states that 2.5” Instantaneous Couplings to BS 336 are tied in by binding (’bound in’) with galvanized mild steel wire of a diameter 1.6mm and applied over a hose guard of synthetic fibre. However this only applies to BS 336 Couplings (2.5” Inst) but is still good practise to wire the coupling on. Other couplings such as Storz and other European fittings are commonly wired on without guards. Also multi serrated type couplings must be secured by 20 continuous turns of wire and ribbed type couplings by at least eight continuous turns on both sides of the rib.
There are other ways of fitting the couplings to the hose for example using clips etc, however we would always recommend that couplings are fitted using wire.
