Manufacturer series reference. Confirm the exact order code, mating parts and stated conditions for the quoted configuration.
Overview
HMF is a formable corrugated metal hose for static routes where a straight rigid tube is impractical. The pictured complete hose is a series reference, not an exact length or port-size order code.
Construction and interfaces
The manufacturer specifies a 316L stainless corrugated hose and 316 or 316L stainless end connections. It is all-metal and intended to hold a manually formed shape after installation.
Selection
Published nominal hose sizes span 1/4 to 1/2 in.; the manufacturer gives a series working-pressure range from vacuum to 9.3 bar (135 psig). Confirm the selected size, ends, temperature and installed bend before using a value.
Configuration options
The official HMF order chart lists fractional/metric tube adapters, rotatable female/male FR fittings and tube-butt-weld ends, as well as selectable lengths. FITOK's example SS-HMF4-FT4-M500 decodes to a 1/4 in. HMF hose with 1/4 in. tube adapters at both ends and 500 mm overall length; it is an ordering example, not the unidentified photo configuration. Not all end combinations are available.
Application limits
FITOK's technical note says HMF is not suitable for dynamic applications. The selected ends, bend, temperature and finished assembly rating must be checked; no coolant-specific compatibility or bend-life result is claimed for this site.
