Threaded Flexible Metal Hose
Size DN6(1/4”)- DN100(4”)
Fustar introduced six threaded nut flexible metal hose automatic welding production lines in 2009 for the production of high-precision threaded flexible metal hoses, which greatly improved the quality of the hose and broke the metal hose length limits. The thread NPT female threaded nut flexible metal hose has a great progress than before.The net wrapping waveform tube is a main pressure-bearing part, as well as a protection parts for metallic flexible hose. It’s very important to various metallic hoses. Fustar match the layers of woven stainless steel wire or steel strip for customers according to the pressure in the pipe size and applications. You can find the threaded NPT flexible metal hose that you need. We also have a lot of other similar products, like helical flexible metal hose, stainless steel braided flexible metal hose, solar heating for pools solar flexible metal hose and so on, high quality and best price for all of you.

Features of Threaded Flexible Metal Hoses
· They threaded NPT flexible metal hose is accommodate expansion and movement, serve as a flexible connection between mobile and static elements of mechanical equipment, neutralise of vibrations, equalize unavoidable assembly tolerances. They are used as extinguishing and loading hoses, as fuel hoses, etc.
· For protection against mechanical influences, for example impermissible buckling and abrasion, we supply our stainless steel corrugated hoses with external or internal protective a graffe hose made of stainless steel.
· For protection against contact or for danger-free handling we equip our stainless steel threaded flexible hoses with external thermal insulation. Fustar stainless steel npt female threaded flexible metal hoses are used in all temperature ranges from - 196°C to +600°C, and from a high vacuum up to a pressure of 200 bar.
Applications of Threaded Metal Flexible Hose
Fustar stainless steel female threaded nut flexible hoses are universally applicable for practically all fluid and gaseous media as well as pumpable solid substances, if necessary using a PTFE liner as protection against especially aggressive media or to attain a non-adhesive inner wall.We provide various metal flexible hoses, you can choose corresponding products for your projects.
