Start with the Connection You Need

Choose the primary connection family first. Metallurgy, braid construction, overall length, and application-specific requirements are selected or reviewed within the product family.

Fast path to standard configurations

Standard & Quick-Ship Configurations

Use this path only when a standardized configuration fits the job. Supported online families use controlled size, OAL, connection, and pricing rules; specialty requirements route to engineering review.

Typical selection sequence

  • Nominal hose size
  • Overall length
  • Hose and braid metallurgy
  • Single or double braid
  • End connection type
  • Fitting material
Pressure and temperature are engineering inputs—not marketing badges.

Validated ratings depend on hose construction, size, braid, temperature and fitting limitations. Use the technical data or submit operating conditions for review.

Metal hose anatomy

Know What You Are Specifying

A metal hose assembly is a system of hose, reinforcement, transitions and end connections. Correct selection depends on the complete assembly—not only the nominal hose diameter.

Double-braided stainless metal hose assembly used to illustrate typical assembly components
Shown product: 316SS double-braided flanged metal hose assembly. Component details vary by selected assembly.
Corrugated hoseFlexible pressure-containing hose element; metallurgy and geometry are product-specific.
Outer braidReinforcement used to control pressure thrust and support the hose construction.
Optional second braidUsed only on products/configurations designed and validated for double-braid construction.
Braid band / collarCaptures and transitions the braid at the end of the flexible hose section.
Weld transitionJoins the hose/braid termination to the specified end fitting construction.
End fittingThreaded, flanged, grooved, JIC or specialty connection as supported by the selected product.
Overall lengthAssembly end-to-end dimension used for configuration, installation and pricing where enabled.
Bend-radius considerationsMinimum bend requirements are specific to hose construction and motion; do not infer them from appearance.

Shop by application

Start with the Piping Problem

Use dedicated application paths when service conditions matter more than connection style.

Engineering calculators

Calculate Before You Specify

Use the engineering tools to evaluate pressure derating, thermal growth, hose geometry, pressure drop, guide layout, and seismic project conditions before selecting an assembly or submitting an RFQ.

Secondary engineered products

Supporting Metal Hose Systems

Flex Pipe USA is focused on metal hose as the primary product path. Rubber expansion joints, metal compensators, seismic V-Loops, and pipe anchors remain available as secondary engineered-product paths.

Metal CompensatorsAxial pipe compensators and related metal expansion products remain available as a secondary engineered-product path.Rubber Expansion JointsRubber expansion-joint requirements route through RFQ and application review rather than the primary Metal Hose navigation.Seismic V-LoopsBraided flexible metal-hose loop products for seismic piping movement.Pipe AnchorsSteel-pipe and copper-tube anchor clamps for engineered piping restraint applications.

Seismic movement solutions

Seismic V-Loops for Multi-Axis Piping Movement

Use the Seismic V-Loop family when piping must accommodate building or structural movement in multiple directions. Standard product paths include 2 in. and 4 in. movement classes with threaded NPT, Class 150 flanged, grooved, weld-end, and copper-sweat connection families.
