Braid Layer Code Key

  • AP is an alternative braid design to allow corresponding pressures
  • 2x is braiding that matches up to corresponding pressures
  • Please contact us if you have any questions about braiding. Call 410-327-0758 or Email: sales@flexfithose.com
  • Please consider the performance/pressure impact of corrections for media temperature for your selected material


Select our flexible all metal hose for your applications that require flexible hose assemblies for more extreme temperatures, with similar pressures to our PTFE hose assemblies . Ranging from 1/4” up to 12” in diameter, the flexible metal hose is constructed with a corrugated stainless steel liner, and is sold alone, or reinforced with one or more outer covers of braided stainless steel to meet your process application requirements. Varying metal strengths of the corrugated liner and additional layers of braiding are available for the flexible metal hose as well. Please consult the data sheet, or contact us to determine which strength and reinforcement of braided stainless steel is needed to meet your process requirements. Industrial hose fittings , offered by FlexFit Hose, are welded onto the hose, providing a strong, flexible metal hose assembly. All metal hoses are an ideal option when you need a high temperature hose or flexible metal hose. These high temperature hoses are used in applications, from Cryogenic up to 1500° F, at varying pressures. Flexible metal hose is used for applications such as:

  • suction
  • conveying and transporting chemicals
  • liquid gas
  • coolants
  • steam transfer
  • oil
  • and more

If you are unsure which flexible metal hose type with varying stainless steel strengths and outer braid layers, you should purchase, be sure to submit our Request a Quote form , providing the media/chemical being transferred through the flexible metal hose, working pressure and temperature. We’ll respond promptly to help.

*larger sizes of flexible metal hose are available, please contact us if you are need of a size not listed.
