Hose assemblies are fabricated by welding the stem and butt of the hose ends together and welding the fittings onto the metal flex hose
Reasons to choose metal flex assemblies
Need for the strength of a steel tube with the flexibly of a hose.
Great heat resistance
High pressure rating
Reasons to consider alternative solutions:
Fabrication of metal flex hose assemblies involves welding the seam and butt as well as a fitting attachment. If not welded correctly, a leak path can be created.
Metal flex assemblies are not readily available in most markets
A combination of the hard lines and flexible hoses can also be a great solution to unique challenges. It would be the most desirable combination if vibration is severe
