Riverstone Parts Co

Riverstone Parts Co, a self-certified small disadvantaged business based in Sugar Land, Texas, supplies industrial valve and pump components to the Department of Defense as a prime contractor exclusively through full-and-open purchase orders placed by the Defense Logistics Agency's Land and Maritime division. The vendor operates 100% in the prime role, with all six awards issued by a single customer agency across a two-year snapshot (2025–2026).

Riverstone's federal footprint is narrow and specialized. The vendor has delivered rotary pump parts kits, solenoid valves, float valves, and hand bypass valves in support of DLA's military logistics and inventory operations. Representative awards include two identical $29,411 firm fixed-price purchase orders for rotary pump parts kits awarded under Total Small Business set-aside (January 26, 2026, and February 27, 2026, with ultimate completion dates of March 9 and April 10, 2026, respectively); a $33,328 solenoid valve purchase order (January 13, 2026, completion February 10, 2026); a $24,985 float valve order for 19 units (December 22, 2025, completion January 26, 2026); and a $15,134 hand bypass valve purchase order (August 28, 2025, completion September 17, 2025). One $2,940 solenoid valve purchase order (January 20, 2026) was awarded without set-aside designation. All work is performed in Sugar Land, Texas, with 20-day to 168-day delivery windows typical of component procurement.

Customer concentration is complete: 100% of awards and combined potential value ($135,000) flow from the Defense Logistics Agency Land and Maritime. The vendor competes under both Total Small Business set-aside and full-and-open designations, winning four awards under NAICS Industrial Valve Manufacturing and two under Measuring, Dispensing, and Other Pumping Equipment Manufacturing. Activity is nascent — two awards in 2025, four in 2026 — and dollar volumes remain sub-$150,000. All awards to date have reached ultimate completion or are scheduled to close by April 2026; no recompete cliff or ongoing task-order vehicles anchor the portfolio. Riverstone carries no subcontract relationships and no parent vehicle seats. The vendor's federal posture is transactional, buy-this-part order-by-order procurement with DLA, rather than strategic or multi-agency.
