RFP Title


Eliminating Leaks in Pressure Control Systems
RFP Description
NineSigma, representing a Global Regulator Manufacturer, invites proposals for novel Seat or Seal technologies that are compatible with high-pressure oxygen applications.

Pressure control systems ensure the safe and efficient regulation of gas flow. Highly specialized seats and seals provide a critical barrier in such operations, while preventing against leakage in the closed stage. For oxygen service applications, these components must not only withstand high pressure cycling at temperature, but also meet performance specifications for ignition testing.


Traditionally, seats and seals are manufactured from a limited range of materials:

  • Seats: Thermoplastics, PTFE, PCTFE, PEEK, Neoprene (Chloroprene), PA
  • O-Rings: EPDM, FKM, Nitryl, PTFE, Neoprene, silicone
  • Back-up Rings: PTFE, PA


However, these materials are prone to a variety of issues such as creep at temperature, compatibility with gases, deformation under load, and lack of resistance to ignition.


NineSigma’s client seeks to identify novel solutions for licensing or development that can improve upon current standards for function and durability in their seats and seals.  Solutions describing materials, manufacturing capabilities or novel component designs (including alternative geometries or integrated solutions) are of significant interest.





Key Success Criteria
The successful technology will:
  • Be compatible with reactive / flammable gases
  • Limit leak rate from 10^-4 to 10^-9 SCCS
  • Maintaining function and structural integrity over 5000 pressure cycles under the following conditions:
    • Application pressures from 150 to 6000 psi
    • Operating temperatures from -60F to 140F





Possible Approaches

Possible approaches might include, but are not limited to:

  • Cross industrial solutions
  • Novel material solutions
    • Co-molded materials
    • Engineered polymers or polymer blends
    • Coatings and surface treatments
    • Lubricants
  • Design-based solutions
    • Innovative component geometries
    • Integrated back up ring or design that does not require a backup ring
    • Energizing seal design


NineSigma’s client will consider partial solutions for collaborative development opportunities.



Approaches not of Interest

The following approaches are not of interest:

  • Material solutions that do not improve upon current performance characteristics for the traditional materials listed above
  • Fluoropolymer solutions are undesirable due to European standards.
