Professional Applications of Double Jacket Fire Hose
It is specially suitable for fire fighting at tough conditions. Besides, it can serve in ship, petrol, chemical, agriculture and mine. Double jacket fire hose is specially designed for fire fighting. Besides the wild, it is also suitable for fire fighting in office, store room, super market and building.
Durable Construction: It absorbs polyester as the raw material. While polyester is one of the best synthetic fibres, it is famous for being durable and strong. Together with the braid tech, it becomes more strong in structure.

Superior Performance & Strength
Double jacket fire hose can bear higher pressure than single layer hose. Besides, it has better abrasion resistance. Therefore, it has a longer service life, which is 2-3 times that of a single layer hose.
In-depth Analysis of Lining Materials
As for the lining, we offer you PVC, rubber and PU.
PVC Lining: Light in weight and flexible. It is very cost-effective; however, it can be brittle at very low temperatures. Once affected by external force, PVC may crack and age over time, potentially releasing toxins at high temperatures.
Rubber Lining: Can withstand both low and high temperatures. It is resistant to oil and ozone. Presently, rubber lining fire hose is the most commonly used option in the industry.
PU Lining: Develops rapidly with the best temperature resistance. It remains flexible at -40℃ and can work at 200℃ for the long term. It resists chemical corrosion from acids and alkalis, making it ideal for transferring water from rivers to farms where sand and impurities are present.
Frequently Asked Questions
Why choose a double jacket fire hose over a single layer hose?
Double jacket fire hoses can withstand much higher pressure and offer superior abrasion resistance, resulting in a lifespan 2-3 times longer than single layer hoses.
What are the primary applications for this fire hose?
It is ideal for tough firefighting conditions, including marine, petroleum, chemical, agricultural, mining, and commercial building environments.
What is the advantage of PU lining in fire hoses?
PU lining offers extreme temperature flexibility (-40℃ to 200℃) and excellent chemical resistance against acids and alkalis, along with better pressure properties.
Is rubber lining still a good choice?
Yes, rubber lining is currently the most widely used due to its ability to handle both high and low temperatures and its resistance to oil and ozone.
Can these hoses be used for agricultural water transfer?
Absolutely. Specifically, the PU lined hoses are designed to handle the corrosion from sand and impurities found in river water used for farming.
Are there any drawbacks to PVC lined hoses?
While cost-effective and light, PVC can become brittle in extreme cold, may crack under pressure, and can age or release toxins at high temperatures.
