Fire Coupling Factory Direct Sales

Fire coupling is a hose used to transport flame retardant liquid such as high pressure water or foam. The traditional fire coupling is lined with rubber, and the outer surface is wrapped with linen braid. The advanced fire coupling is made of polymer materials such as polyurethane. Both ends of the fire coupling have metal joints, which can be connected to another hose to extend the distance or to the nozzle to increase the liquid nozzle pressure.

Fire coupling is divided into two types: lined and unlined. Lined fire coupling include cotton, nylon rubber lined hose, polyester rubber filled hose, Hemp plastic coated water hose. The unlined water hose includes cotton water hose, linen water hose and ramie water hose. According to the working pressure, it is divided into six categories: 0.8MPa, 1.0MPa, 1.3MPa, 1.6MPa, 2.0MPa and 2.5MPA. According to the diameter, it is divided into four categories: 50(2 inches), 65(2.5 inches), 80(3 inches) and 100(4 inches). According to the weaving method, it can be divided into plain water hose and twill water hose. The length of water hose generally set to 20 meters.
