DnF Below SAT - Part 12 (Brand Name - Circle Seal Check Valves_Redacted)_Redacted.pdf

This is a Determination & Findings (D&F) document for a sole source purchase order by the Air Force Life Cycle Management Center (AFLCMC/HNCKIA).

The acquisition involves a brand name purchase order for 300 Circle Check Valves, part number 259A-1PP-15, manufactured by Circle Seal Controls. The contracting activity justified the sole source procurement under RFO 11.204(a)(2)(ii) (Brand Name authority), determining that the particular brand name is essential to the Government's requirements and that market research confirmed no similar products from other companies meet the agency's needs. Technical Application Products requires this specific brand because the Circle Seal check valve is a replacement component authorized and approved by the unit's Configuration Control Board. The valve is designed to address a specific seal failure issue due to tight sealing service requirements, and no other brand of check valve meets the agency's minimum needs. The customer conducted market research confirming the product is commercial and available through multiple distributors of the Circle Seal manufacturer. The Contracting Officer determined the sole source action is justified under the applicable regulation. The document is signed by a Contracting Officer and dated 7 July 2026.
