FLEXIBLE HOSE 27A UNBRAIDED

General Introduction

The flexible sprinkler hose is a water supply component designed with maximum flexibility, commonly used to connect the fire protection piping system to sprinkler heads. Thanks to corrugation technology, the hose can be bent in multiple directions without deforming or compromising its structure. This technology is also applied in flexible joints, electrical conduits, and gas pipelines.

Product Catalog: FLEXIBLE HOSE 27A

Structure

The hose is manufactured from stainless steel (commonly SS304) with corrugated design for flexibility, and an additional braided stainless-steel outer layer for reinforcement. This outer braid enhances resistance against bursting, cracking, and external impacts.

Manufacturers also supply a full range of installation accessories such as ceiling brackets, support bars, couplings, threaded outlets, and clamps to ensure quick installation and compatibility with different sprinkler systems.
