CUSTOM METAL HOSE & ASSEMBLIES
Our MATCHLESS Corrugated Metal Hoses are designed as general all-purpose hoses for conveying liquids and gases, usually at high temperatures and pressures, while maintaining flexibility.
Braiding enables use at high pressures and attenuates vibration. Each annular corrugation is a separate element engineered to impart optimal flexibility for each size of hose we offer.

We offer a wide range of fittings to use in metal hose assemblies. Almost any fitting can be attached to corrugated metal hose. Welding or brazing must be compatible with the metals used.
METAL HOSE TERMINOLOGY
Annular: A Hose profile that is designed so each convolution
is a separate circle or ring.
Braid: Woven wire cover placed over hose which prevents
elongation of the hose and permits higher working pressure.
Close Pitch: More corrugations per foot which renders the
longest fatigue life and minimum bend radius.
Constant Flexing Bend Radius: The minimum radius to
which a hose can be repeatedly bent and render satisfactory
Constant Motion: Motion that occurs on a regular cyclic
basis at a constant travel.
Fittings: Parts attached to the ends of metal hoses so that
they can be connected to other components such as flanges,
unions, nipples, etc.
Flow Velocity: When the flow velocity exceeds 75 ft./second
liquid, 150 ft./second gas in braided hose, a flexible metal
liner should be used.
Intermittent Motion: Motion that occurs on an irregular cyclic basis.
Maximum Test Pressure: The maximum pressure a hose
assembly should be subjected to for testing purposes. Based
on 150% of the Maximum Working Pressure.
Media: Conveyant in a hose assembly such as gases,
Operating Conditions: Temperature, Pressure, Media,
Motion and Application involved.
Random Motion: Uncontrolled motion that occurs usually
from manual handling of hose.
Rated Burst Pressure: Pressure at which hose can be
expected to fail. Braid will normally fail before core burst.
Safety Factor: Difference between working pressure and
rated burst pressure.
Shock or Pulsating Pressure: Shock, pulsating or surge
pressure can cause premature failure of hose.
Static Bend: Minimum center bend radius to which flexible
metal hose may be bent for installation.
Vibration: High frequency, low amplitude
Working Temperature: Temperature to which hose will be
subjected during operation
