Different Types of Fire Hoses
Fire hoses are pipes that are used to attach with different firefighting systems to convey the water and other fire extinguishing agents from the source to the fire incident.
They are extremely helpful in carrying the fire extinguishing agents at long distances, at different heights, and at different angles.
The different types of fire hoses are available, so they can be used extensively in different environments.
Fire Hose Formation
Earlier cotton fire hoses were used but now fire hoses are made up of nitrile rubber tubes, insulated with a woven polyester jacket, but the fire hoses are classified into different types based on different factors, such as the material used in the manufacturing of fire hoses, their thickness, and the way they are constructed.
The different types of fire hosesย are mentioned below:
1- Single Jacket Fire Hose
In a single jacket fire hose, the internal rubber hose is covered with only a single layer of spun polyester fabric. Such fire hoses are best to use periodically or temporarily, and for long-term storage. Another plus for this type of fire hose is that it is the most economical among the other types of fire hoses.
2- Double Jacket Fire Hose
In the double jacket fire hoses, there are two layers of protective jacket over the nitrile rubber tube to add an extra layer of durability. The double-checked fire hoses are used by municipal fire departments and in heavy industrial applications. These advanced fire hoses are extremely useful in fire industries to operate many firefighting systems and apparatus.
3- Rubber Covered Fire Hose
The rubber-covered fire hoses are manufactured to resist different elements, such as ozone, oxidation, and petroleum/ chemical products. Their nitrile rubber tube is insulated with 100% synthetic yarn reinforcement.
This design is according to the ‘through-the-weave’ principle. It ensures that the fire hose will not be split when fuels, oils, and other low-concentrated liquids will flow through them.
These are the three basic types of fire hoses that can be combined to create the hoses used for various functions.
Further types of fire hoses include the supply lines and the booster lines.
4- The Supply Line Fire Hose
The supply line fire hoses are responsible for delivering the main water supply. Their inside diameter ranges from three inches to six inches. The supply lines are also known as the intake lines.
The supply line fire hoses should be constructed with an extremely durable fabric that is capable of handling enormous pressure, and they are not supposed to be very flexible. For this season, the fire hoses are layered with durable fabric making them able to handle a lot of pressure, and often the material has a low flexibility.
Large Diameter Hose (LDH)
In supply lines, large-diameter hoses are preferred, as they are capable of withstanding big flow even at low pressure. These fire hoses are capable of supplying large quantities of water from one place to another. There is a benefit of LDH over the small diameter hoses, that they can deliver water with less friction loss.
5- Booster Fire Hoses
Booster fire hoses are used to deliver a single stream of water. It can be handled in both ways, by a single person or by a team. Their diameter ranges from 1-3/4″ to 2-1/2″ and they are also known as the attack lines. The booster fire hoses are branched off.

Best-Suited Fire Hose Fabric for Different Purposes
The supply lines’ fire hoses are rigid and non-collapsible. These hoses have a rubber lining, layers of fabric, and often wire mesh reinforcements. To increase the flexibility, plastic mesh instead of the wire is used in many types of hoses. The hose materials are insulated with the polymer’s reinforcers, for additional strength, heat resistance, and pressure capacity. By adding such additives, the flexibility of these fire hoses changes, therefore these types are then known as ‘soft’ or ‘hard’. Both have their benefits.
The fire hoses made up of woven fabric or impregnated, are soft. These hoses are comparatively easy to handle and can be used repeatedly for a quick deployment. On the other hand, hard fire hoses have the benefit of rigidness and non-collapsibility. These are best suited for places where high-pressurized water is not available.
In addition, there are different types of fire hoses, designed for making them usable in different instances.
6- Industrial Mine Hoses
The industrial mine hoses are suitable for carrying out underground mining operations. To get reduced weight and increased flexibility, such hoses are built with a single jacket exterior woven from polyester. In this way, they also become capable of resisting gravitational pressure and hydrolysis of the hose.
7- Marine Washdown Hoses
Marine washdown hoses are suitable to cater to rough outdoor conditions, where they come across frequent exposure to raw, fresh, or salt water. They are perfect for ships and offshore facilities.
8- Industry Specific Hoses
Industry-specific hoses can be used diversely. Having such hoses means that you are capable of handling the fire in any situation.
Best Types of Fire Hoses Based on Water Supply
The fire hoses are distinguished by another factor which is the supply of water.
9- Municipal Fire Hose
In the cities, municipal water supply is readily available, so in these areas the municipal fire hoses are ideal. They are made up of soft fabrics because the water supplied to these hoses comes at a high pressure.
10- Forestry Fire Hoses
In villages, the municipal water supply is not available. The most common source of water supply is a lake or a river. For those areas, forestry fire hoses are the best. They are built in such a way that forestry fire hoses can resist the abrasive and irregular terrain. The firefighters put the hoses into the lake or the water pump, to get water. Here the rigid fire hoses are required to resist the water pressure. If a collapsible fire hose is used in such scenarios, it will collapse so a non-collapsible fire hose is required.
Conclusion
The fire hoses are the pipes to deliver water from the fire source to the fire, for extinguishing it. There are different types of fire hoses based on different factors such as hose fabric and water supply sources. The different types of fire hoses include single-jacket fire hoses, double-jacket fire hoses, rubber-cover fire hoses, supply line fire hoses, booster fire hoses, industrial mine hoses, marine washdown hoses, industry-specific hoses, municipal fire hoses, forestry fire hoses.
All these types of fire hoses are suitable for extinguishing the fire in different areas and different situations.
