Fabricate custom c-seals for VMS instrument

This contract is a sole-source procurement under FAR 12.102(a) for the fabrication of 248 custom C-seals for the DAVINCI Venus Mass Spectrometer (VMS) instrument, awarded exclusively to Parker, via DBR Industries, Inc., due to the proprietary nature of the Parker C-ring design and the unique materials and processes required to meet NASA’s stringent performance standards. The seals, identified by specific Parker part numbers such as NH-762108 through NH-762111, are critical hermetic components for flanged interfaces on the QMS and GPS subsystems, and must replicate the quality and performance of seals successfully used in prior NASA missions like SAM, NGIMS, and MOMA. The work is performed at Parker’s facility in Connecticut, with delivery required to NASA Goddard Space Flight Center in Greenbelt, Maryland, within 20 to 27 weeks after award, with certain components having staggered delivery timelines. There is no competitive bidding process, as Parker is the only vendor with the proven qualification, testing history, and technical capability to meet the exacting requirements, rendering requalification of alternatives impractical. The contract mandates extreme adherence to cleanliness and leak rate standards, which are the two most critical evaluation factors, with no tolerance for deviation: each seal must achieve a maximum helium leak rate of ≤1×10⁻¹⁰ cc/std cm and be free of visible contamination, scratches, or gold nodules under 1X magnification, as defined by the VC-10X-1000 standard. All seals must undergo third-party cleaning in compliance with IEST-STD-CC1246A Level A in a controlled cleanroom environment using nitrile gloves and 99.99% pure nitrogen with 0.5-micron filtration. Each seal must be individually vacuum-sealed in Ultra Low Outgassing polyethylene bags with serialization including company name, lot number, part number, and manufacturing date; multiple sealed units are grouped in a common outer bag. A sample of at least three seals or 10% of the lot, whichever is greater, must be leak tested prior to shipment, and all deliveries must be accompanied by material certificates and test reports. While no formal FAR clause listing or financial details like CLINs or payment terms are provided, the estimated contract value is $27,000, and all documentation and delivery processes are managed through the NASA Shared
