D & M Hydraulic Sales & Service, Inc.

D & M Hydraulic Sales & Service, Inc., a woman-owned small business based in Waipahu, Hawaii, supplies specialized hydraulic and pneumatic hose assemblies, fittings, gauges, and related components to the U.S. Navy and federal maritime agencies almost exclusively as a prime contractor under total small business set-asides. The company has operated continuously since SAM registration in 2001 and competes predominantly in small business set-aside vehicles, with all but two of its recent 325 federal awards designated as total small business set-asides.

The Naval Sea Systems Command accounts for the dominant share of D & M's federal work. Naval Sea Systems Command has placed 206 awards (95% of total award count) valued at $1.3 million in combined potential value, followed distantly by United States Pacific Fleet Forces with 87 awards ($188 thousand) and Naval Supply Systems Command with 9 awards ($164 thousand). The top three naval customers account for 95% of all awards. Customer concentration is extreme and stable: the Navy represents nearly all dollar value and volume, with minimal exposure to other federal agencies including the Department of the Army Pacific Command ($35 thousand) and the U.S. Coast Guard ($16 thousand).

D & M's capability portfolio centers on nonmetallic hose assemblies engineered for marine and naval vessel environments. Representative recent work includes a $162,170.10 total small business set-aside purchase order from Naval Sea Systems Command (July 2025) for 144 hose assemblies across three configurations (4-inch and 2.5-inch diameter, 25-foot to 50-foot lengths) with UV protection and abrasion resistance for Pearl Harbor freshwater and saltwater headers; a $105,328.22 purchase order from Naval Supply Systems Command (October 2025) for 4-inch by 50-foot hose; and a $71,399.80 purchase order from Naval Sea Systems Command (February 2026) for general hose assemblies. The company also supplies ancillary components including hydraulic pumps, pressure gauges, and pneumatic air hoses. Work is performed at the contractor's facility in Waipahu, Hawaii.

The top product-service categories tracked by NAICS reflect this portfolio: Other Metal Valve and Pipe Fitting Manufacturing (56 awards), Rubber and Plastics Hoses and Belting Manufacturing (50 awards), and Fluid Power Valve and Hose Fitting Manufacturing (41 awards). By PSC, Hose, Pipe, Tube, Lubrication, and Railing Fittings dominates with 116 awards, followed by Hose and Flexible Tubing (65 awards). Activity has grown modestly in recent years—two awards in 2022 to nine in 2025—though the company's annual award volume remains small and individual purchase orders typically range from $10 thousand to $162 thousand. The company has minimal subcontract exposure (one sub award on record for supply hoses under a POL Multiple Award Construction Contract).
