Product catalog summary
Product Description
The document describes a flame-resistant convoluted multilayer PTFE hose designed for demanding marine and offshore applications. It features a fiberglass covering and wire braid reinforcement. The hose is designed for easier crimping and offers a minimum 150K impulse cycle life expectancy at elevated temperatures. The convoluted profile improves vacuum resistance and allows for easier draining and a smaller bending radius. Available in virgin PTFE and carbon-lined anti-static versions, it supports the transfer of common fluids and gases.

Properties
  • Application: Suitable for installation on all vessels classed by DNV GL.
  • Design: Available in sizes from 3/8” to 2”, featuring flame-resistant PTFE helical convoluted lined hoses with fiberglass covering and wire braid reinforcement.
  • Inner Layer: Virgin and anti-static inner layer with a PTFE impregnated fiberglass cover.
  • Outer Layer: 304 or 316 Stainless steel braid.
  • Temperature Range: -50°C to +150°C.
  • Material: PTFE BS2782 Method 327A:1993, ASTM-D 882.
  • Certification: DNV GL class programme CP-0183 – Type Approval of flexible hoses of non-metallic material.

Specifications
The document includes a detailed table listing part numbers, descriptions, nominal inner and outer diameters, maximum working and burst pressures, minimum bend radius, and vacuum ratings for both standard and anti-static versions of the hoses.

Conclusion
The DNV GL range of PTFE hoses by Kongsberg Automotive is tailored for marine and offshore applications, offering durability, flexibility, and compliance with DNV GL standards. For bespoke assemblies, inquiries can be directed to the sales team.

DNV GL Range FLUID TRANSFER SYSTEMS Product Description Properties Application 3/8” - 2” Flame resistant PTFE helical convoluted lined hoses. Convoluted multilayer PTFE hose with fiberglass covering and wire braid reinforcement Inner layer Virgin & anti-static inner layer with a PTFE impregnated Fiberglass cover Outer layer 304 or 316 Stainless steel Braid Temperature Min/Max PTFE BS2782 Method 327A:1993 ASTM-D 882 Available in both virgin PTFE and carbon lined anti-static versions allowing the transfer of all common fluids and gasses used in marine and offshore applications. Accepted for installation on all vessels classed by DNV GL. Flame resistant convoluted multilayer PTFE hose with fibreglass covering and wire braid reinforcement for use on demanding marine and offshore applications. The convoluted profile ensures easier crimping of the hose and with the approved DNV GL fitting and ferrule range now offers a proven minimum 150K impulse cycle life expectancy at elevated temperatures. The new convoluted profile offers improved vacuum resistance where negative pressures may be detrimental to the life cycle of the hose assembly. The helically convoluted design allows for easier draining when compared to other nonPTFE hose types whilst also giving a smaller bending radius allowing the fitment of the product in tighter confines. DNV GL class programme CP-0183 – Type Approval of flexible hoses of non-metallic material DNV GL Convoluted Range Part Number Available as bespoke made assemblies from Kongsberg Automotive to exacting DNV GL standard.
