Corrugated Stainless Steel Flexible DN 1/4-12 INCH Corrugated Hose With Assembly
The flexible metal hose can be used widely in systems like water, steam, hot oil, and gas with their resistance to pressure and flexible structure.
They are utilized for conducting liquids, compensating the problems originating from installation, and absorbing vibrations and expansions.
Flexible metal hoses may be strengthened by double braiding in order to increase their resistance to pressure and environmental conditions. It is also possible to reinforce them by springs with different wire thicknesses or by strip wounds to lengthen their service life for more severe environmental conditions.

Flexible corrugated metal hose
Construction of Flexible Metal Hose
Inner Core:
Corrugated Stainless Steel
· Flexible metal hose stainless steel core strengths are available in 304, 321 and 316L stainless steel
· Stainless steel tubing formed into corrugations parallel to one another
· Helical / Convoluted option available upon request
Outer Core:
Braided Stainless Steel Layers
· Purchase corrugated core hose with no layers, single or double braided
· Flexible metal hose outer braid layers made from 304 stainless steel
· See braid layer code key at the bottom of this table
Benefits of Flexible Metal Hose
· All metal hose - corrugated stainless steel core, sold standalone or with braided steel layers
· Pressure tolerances include full vacuum to those listed in the spec table below
· Application Temperature ratings from Cryogenic to 1500° F
· Meets or exceeds ISO 10380 at a maximum working pressure
Corrugated metal hoses have a bendable and bendable structure; Reliable, quick and easy connection with time-saving, pressure and temperature-resistant hoses.
Flexible metal hoses without braids eliminate the problems of rigid connection. With very short distances between pipes and equipment, such as elbows, cuffs and sleeves instead of mounting with elements, these hoses less time spent, you can save time.Corrugated metal hose is a general purpose industrial hose and is available in different grades of stainless steel including ss304, 321, 316L
Comflex metal hoses with long service life; practical, safe, quick and easy installation. Thanks to their flexible structure, they are safe against vibration and noise.
