Products Details

What is the Stainless Unbraided Hose with Straight Nipple ？

Stainless Unbraided Hose with Straight Nipple（Unbraided flexible sprinklers hose & fittings) assembly consists of an unbraided corrugated hose, inlet steel fitting to connect the branch line, outlet fitting to connect the sprinklers, and bracket assembly to mount on the ceiling.The fire hose is composed of stainless steel bellows hose, joint fittings and fixed bracket groups, which provides an innovative simple and efficient installation method for the end sprinkler of the fire sprinkler system, replacing the traditional installation method of short pipe sleeve + steel parts.

The advantage of Flexible hose fittings

● Safe & Reliable
All the parts fexible hoses are manufactured in corrosion resistant and high-powered stainless steel with 100% leak tested prior to leaving the factory and the environmental temperature resistance being as high as 107℃/225℉
● Easy and Quick installation
No special tools are required and It only needs the simple use of wrench, screw driver and pipe sealing tape, etc, in the installation with the minimal amount of time. The fexibility hose can be adjusted based on the installation space and can also be combined with 90’ elbow, which allows hose to be fxed in limited installation space.
● Economizing on cost With the unique connection mode of fexible hose, the MECH brand is much more time and cost saving and with no need of any machine against traditional hard pipe system installation.
● Environmental Friendly
The flexible hose can be re-shaped and relocated to suit the final sprinkler location on the ceiling without draining the system, avoiding the pipe wasted by the inaccurate measurement. No sprinkler displacement even after high pressure test and eliminating the need for an oversized ring around the sprinkler.
● Seismically
The stainless steel hose can absorb seismic shock, and protect the sprinkler system to maintain normal operation in the case of an earthquake.
