The Naval Supply Systems Command (NAVSUP) intends to issue a sole source award to Petroleum Analyzer Company, LP (PAC) for Herzog Multi-Range Viscometer repair parts. Market Research has determined that Petroleum Analyzer Company (PAC) is the sole manufacturer and service provider for the Herzog brand of equipment. This notice of intent is for information purposes only. All sources eligible to provide this requirement must respond in writing. Responses must be supported with clear and convincing evidence to clearly articulate the ability to provide this requirement as outlined above. A request for documentation will not be considered as an affirmative response. If no responses are received, within two (2) calendar days after publication of this notice, to the effect that comparable items are available, and that it is more advantageous to the Government than obtaining this product through a sole-source contract, then a sole source acquisition award will be made.
