Stainless steel flanged universal hose assembly consisting of stainless steel convoluted hose grade 321, complete with stainless steel outer protective braid grade 304. Fitted with fixed carbon steel flanges drilled to BS 4504 NP16.


Stourflex stainless steel universal hose assemblies are designed to absorb vibration, accommodate misalignment and lateral movement. They will provide the flexing movements required when piping up to non static machinery or equipment. In addition these assemblies can be used as final connections to oil or gas burners and other general pipework duties including sprinkler racking  systems etc. For use on chilled water, L.T.H.W, M.T.H.W, H.T.H.W, steam, oil, compressed air, and other hot liquids and gases.

  • Maximum working temperature 300ºC.
  • Maximum working pressure see table below.
  • Stourflex stainless steel universal hose assemblies should not be used at both their maximum working temperatures and pressures respectively.
  • Maximum test pressure = 1.5 x working pressure or 1.5 x flange rating whichever the lower.


Stourflex are now able to offer a tailor made flexible lagging jacket to help reduce heat losses on LTHW systems and heat gains & condensation on CHW systems. Please ask for pricing or more information.
