About W. & O. Supply, Inc.

Written by GovTribe AI ·

W. & O. Supply, Inc. Seattle Division is a for-profit maritime equipment and pipe-fitting supplier operating as a subsidiary of the Jacksonville, Florida-based parent W. & O. Supply, Inc., competing as a prime contractor (98% of awards) on full-and-open federal purchase orders with no set-aside designations. The vendor supplies piping materials, valves, fittings, reducers, elbows, flanges, unions, bushings, tees, pipe hangers, strainers, and related maritime components to support naval vessel maintenance, repair, and construction across domestic and international locations, with a secondary footprint in subcontract work supporting shipyard modernization efforts.

The customer concentration is extreme and narrow. The Department of the Navy Naval Sea Systems Command accounts for 380 awards and $968 thousand in combined potential value — representing 73% of all awards in the portfolio and dominating both volume and dollar rankings. The Department of Homeland Security US Coast Guard ranks second with 38 awards and $482 thousand, while the Department of the Navy United States Pacific Fleet Forces, Defense Logistics Agency Land and Maritime, and Naval Supply Systems Command round out the top five. Together, these five customers account for 95% of recent awards. The two rankings track closely; NAVSEA's preponderance in both volume and value reflects the vendor's core relationship with the Navy's primary shipboard logistics buyer. Award values are characteristically small — the portfolio shows $1.8 million in combined potential value across 521 awards, averaging under $3,500 per award, with individual purchase orders typically ranging from several hundred dollars to low five figures. One notable outlier, a $96,323.26 check-valve order to NAVSEA in February 2025, anchors the high end of the vendor's historical range.

Activity volume has grown modestly in the last five years, rising from five awards in 2022 to twenty-one in 2024 and eighteen in 2025. The recompete cliff is negligible: only one award with combined potential value of $1 thousand reaches ultimate completion inside the next twenty-four months, indicating minimal near-term recompete exposure. Top product service codes center on hose, pipe, tube, lubrication, and railing fittings (291 awards), nonpowered valves (58 awards), and pipe, tube, and rigid tubing (45 awards), reflecting the vendor's primary focus on standardized maritime supply items. Category concentration across NAICS spans other metal valve and pipe fitting manufacturing (103 awards), ship building and repairing (78 awards), and industrial valve manufacturing (64 awards), grounding the vendor's profile as a maritime supply-chain component supplier rather than a systems integrator.

W. & O. Supply operates on two parent vehicles: Indefinite Delivery Contract W56HZV17D0086 (3 task orders) and Indefinite Delivery Contract N3943021D2229 (1 task order). As a subcontractor, the vendor supplies specialized piping and valve components to Vigor Works LLC and Vigor Marine LLC on ship modernization projects, including USS Kidd depot modernization periods and USNS Guadalupe delivery work. The subcontractor role includes support to Marine Ventures International for the M/V Independence valve replacement work. Across both prime and sub portfolios, W. & O. Supply's competitive posture is straightforward: low-dollar, high-volume supply of standardized naval maritime components on firm fixed-price purchase orders to a single dominant customer (NAVSEA), with secondary volume from Coast Guard and defense logistics sourcing and structured teaming relationships with regional shipyards.
