The U.S. Coast Guard is requesting quotations for 600 fluid filter elements (NSN 4330-01-676-8523, Aqua-Chem Inc. part) for WMEC RO use, with each element individually packaged and marked, and orders in multiples of 15. Standard commercial packaging is unacceptable, and offerors must comply with the Coast Guard’s specific packaging and bar-coding requirements. The brand-name part is mandatory unless an equal product meets the specified salient characteristics and is approved by the Coast Guard. The award will be a firm fixed-price contract, made on an all-or-none basis to the lowest price technically acceptable offeror. Offerors must be registered in SAM and submit required representations and certifications with their quote.
