The U.S. Coast Guard Surface Forces Logistics Center is seeking quotations for 8 units of a retaining seal plate (NSN 5340-01-665-3439, Fairbanks Morse part number 2251526) for use in WMEC raw water and jacket water pumps. This is anticipated to be a non-competitive sole source award to Fairbanks Morse or an authorized distributor; substitute parts are not acceptable, and each item must be individually packaged and marked per Coast Guard requirements. Interested parties capable of supplying genuine OEM parts must submit complete information, including an OEM authorization letter, to demonstrate their capability. The government intends to award a firm fixed-price contract on a lowest price technically acceptable basis, all or none, under simplified acquisition procedures. No budget or performance location is specified.
