The United States Coast Guard is seeking quotations for 50 units of a specific gas detector (GEOPAL SYSTEM A/S part GP-SA), a brand-name component for the 154' Fast Response Cutter's refrigeration system. Award will be made on a firm fixed-price, lowest price technically acceptable basis, and offers of equal products must meet specified salient characteristics. Vendors must comply with strict MIL-STD-2073-1E packaging, marking, and bar-coding requirements, or use a third party to do so, as standard commercial packaging is unacceptable. Quotations must be submitted via email, and offerors must be registered in SAM with a valid DUNS number. No budget amount or location for performance of services is specified in the description.
