Description
ISI-Certified RRL Hose Pipe (IS 636)
Overview
The ISI-Certified RRL Hose Pipe is a high-performance, flexible fire-fighting delivery hose designed for the reliable transmission of water, foam, and other fire-retardant fluids at high pressure. Bearing the prestigious ISI Mark — a certification from the Bureau of Indian Standards (BIS) — this hose conforms to IS 636:1988/2018 (Specification for Fire Hose Delivery Couplings) , ensuring uncompromising quality, safety, and reliability .
RRL stands for Reinforced Rubber Lined, a construction technology that combines a rubber inner lining with a circularly woven fabric jacket made from a special blend of cotton and synthetic yarn . This design provides the hose with exceptional flexibility, durability, and resistance to high pressure and demanding environmental conditions. The RRL technology means the hose is fabric-reinforced, offering advantages similar to a double-jacketed hose—a hose within a hose . This ensures that even in extreme circumstances where the outer jacket is severely damaged, the inner reinforcement can continue delivering water at operational pressures, averting an emergency situation .
RRL Hose Pipes are the most popular choice among experienced firefighters due to their lightweight construction, ability to withstand high backpressure, and ease of handling . They are an essential component for fire hydrant systems, fire engines, and industrial fire protection networks.
