High Purity Flexible Hoses

High Pressure Flexible Hoses
316 SS high pressure flexible metal hoses are designed for
strong, safe and flexible operation in demanding specialty gas
environments. Zero permeation characteristics do not allow
gas or atmosphere to pass through its wall in either pressure 1/4" Style S (shown with SS Male NPT
or vacuum applications. Ideal for flammable, toxic, high purity and Armor Casing)
and small molecule gases. 316L SS 316L SS corrugated inner core.
n SS core, double SS braid. Style S - 3,850 psi TIG weld Very close pitch for extreme flexibility,
argon purge
high flow, and longer hose life.
n SS core, double SS braid. Style H - 4,800 psi ~20 convolutions/inch, 2x the
industry standard

Monel Inner, Stainless Steel Braid
Monel high pressure flexible metal hoses with SS braid are
ideal for oxygen service where particle impingement failure is a
concern. The SS braid is more economical and allows higher
working pressures than Monel braid.
