About the company
Rudolph Brothers & Co (Rudolph Bros. & CO. Division) manufactures and distributes industrial adhesives, sealing compounds, corrosion-resistant coatings, and specialty chemical products to the Department of Defense as a prime contractor on multiple purchase orders and indefinite delivery contracts, competing predominantly full-and-open with no set-aside posture except where agency set-asides apply to individual orders. The vendor is a for-profit, self-certified small disadvantaged business headquartered in Canal Winchester, Ohio, with SAM.gov registration dating to July 2001.
Rudolph Brothers dominates a single customer's procurement landscape. The Defense Logistics Agency Troop Support Construction and Equipment division accounts for 1,396 awards (91% of the vendor's prime footprint) and $8.9 million in combined potential value. This concentration reflects the vendor's specialized role as a commodity supplier of adhesives, sealing compounds, gasket-forming compounds, rust-arresting coats, and polyurethane coatings for military aircraft maintenance, equipment repair, and construction operations. Two secondary customer clusters exist: the Department of the Air Force Materiel Command Oklahoma City Air Logistics Complex (4 awards, $14.3 million combined potential value), anchored by a $13.344 million indefinite delivery contract (FA812519DA002) for adhesive products supporting Tinker Air Force Base operations; and GSA Federal Acquisition Service (31 awards, $977 thousand). Recent representative work spans routine purchase orders — a $79.846 thousand adhesive procurement from DLA Troop Support in September 2024, a $74.932 thousand insulating varnish order from DLA Aviation in August 2024, and a $39.779 thousand sealing compound delivery to DLA Troop Support in July 2025 — along with the larger Air Force delivery order valued at $348 thousand awarded November 2022 for adhesive products.
Activity has grown measurably: eight awards in 2022, expanding to 31 in 2023, 29 in 2024, 45 in 2025, and 40 awards year-to-date in 2026 (through July). The vendor's primary parent vehicles are two indefinite delivery contracts issued by DLA Troop Support (SPE8ES17D5006 with 431 task orders at $128 thousand combined potential value, and SPE8ES17D5013 with 281 task orders at $96 thousand), plus the Air Force Tinker IDIQ noted above. GSA Schedule GS06FAA367 supports 14 task orders at $61 thousand combined potential value. The vendor holds no subcontractor footprint; one sub-award to ASRC Federal Facilities Logistics, LLC (February 2025) and isolated subs to Amentum Services and General Dynamics Mission Systems represent minimal engagement. Rudolph Brothers' portfolio is narrowly specialized: 1,400 of 1,534 total awards (91%) fall under NAICS Adhesive Manufacturing, with 1,379 awards (90%) under PSC code Adhesives. This extreme concentration reflects the vendor's character as a dedicated adhesive and specialty-chemical distributor rather than a full-service logistics provider — a single-product supplier competing on commodity margins and delivery reliability in a high-volume, low-dollar-per-order environment where DLA Troop Support placement and inventory replenishment dominate the business model.
