About the company
Caplugs, Inc., a Buffalo, New York-based manufacturer of plastic product-protection components including caps, plugs, and specialized equipment, operates as a prime contractor on federal purchase orders issued across twenty-one distinct customer agencies (94% of recent awards) and, infrequently, as a subcontractor on defense industrial programs. The company is not designated as a small business, HUBZone, SDVOSB, WOSB, or other SBA set-aside category, and competes on full-and-open solicitations. Caplugs maintains a named subsidiary, Shercon, Inc., which carries complementary manufacturing capability.
Caplugs' award portfolio is characterized by high frequency, low-dollar-value purchase orders. The company has received fifty-four total federal awards since 2007, with combined potential value of $583 thousand and combined obligated dollars of $828 thousand — indicating fulfillment above initial ceiling values. Recent activity shows three awards in 2021, one in 2023, four in 2025, and one in 2026. Caplugs' primary NAICS categories span All Other Plastics Product Manufacturing (17 awards), Current-Carrying Wiring Device Manufacturing (12 awards), and Air-Conditioning and Warm Air Heating Equipment Manufacturing (4 awards); PSC coding reflects Hardware Commercial (14 awards), Laboratory Equipment and Supplies (7 awards), and Miscellaneous Electric Power and Distribution Equipment (5 awards). Concrete named work includes an $866 purchase order from Naval Sea Systems Command for polyethylene plugs (ultimate completion September 2025), a $51 Naval Sea Systems Command order for poly plugs (April 2025), and a $17,803 purchase order from the National Institute of Standards and Technology for a MOKON WS-5 ICEMAN portable chiller model WS4J05CH (awarded February 2023, completed September 2023).
Customer concentration sits with defense and research agencies. The top five funding agencies by award count (59% coverage) are Naval Sea Systems Command (11 awards, $14 thousand combined potential value), Department of Army Materiel Command Communications Electronics Command (7 awards, $3 thousand combined potential value), and three distinct Bureau of Prisons facilities plus CDC Pittsburgh. By potential value, concentration shifts: Department of Army Materiel Command Research Development and Engineering Command leads with three awards worth $268 thousand combined, followed by CDC Pittsburgh (4 awards, $90 thousand combined), Air Force Wright Patterson (1 award, $64 thousand), and USDA Agricultural Research Service (1 award, $33 thousand). Caplugs holds one indefinite delivery contract task-order vehicle (N0001924D0104) under the Department of the Navy. In its subcontractor role, Caplugs supplied outdoor process chillers to Fluor Marine Propulsion on naval nuclear laboratory management and operations support and circulating oil temperature equipment to an unnamed prime on test facilities operations maintenance and engineering support; Northrop Grumman Systems Corp engaged Caplugs for plastic component manufacturing on FMU-139D/B bomb fuze system production. The recompete window carries minimal risk — activity is episodic and dollars are small — but the broad agency customer base and eighteen-year track record signal reliable supply-chain positioning in niche manufacturing categories.
