Walz & Krenzer Inc.

Walz & Krenzer Inc., operating through its Mapeco Products Division, manufactures custom maritime hardware, gaskets, seals, mechanical components, and specialized watertight closures for federal defense and maritime agencies as a prime contractor (98% of recent awards) on a full-and-open, non-set-aside basis. The company is a for-profit Subchapter S Corporation headquartered in Oxford, Connecticut, classified under primary NAICS codes including Bolt, Nut, Screw, Rivet, and Washer Manufacturing (332722) and Gasket, Packing, and Sealing Device Manufacturing (332999). Work is performed in Oxford and Seymour, Connecticut.

Customer concentration is sharp and maritime-focused. The top five funding agencies account for 90% of recent awards by combined potential value, led by the U.S. Coast Guard (103 awards, $6.2 million combined potential value) and the Defense Logistics Agency Land and Maritime (406 awards, $4.3 million combined potential value), with Naval Sea Systems Command, Military Sealift Command, and DLA Aviation rounding out the active set. DLA Land and Maritime dominates by award count (406 awards) but the Coast Guard's portfolio carries higher average values per order. Award velocity has declined sharply: 122 awards in 2022 falling to 33 in 2026 year-to-date, driven by the transactional, small-order nature of Mapeco's primary DLA business model — the vendor fulfills purchase orders and delivery orders averaging low five-figure and sub-five-figure values for consumable spare parts and hardware components.

Mapeco Products holds five active Indefinite Delivery Contracts with DLA Land and Maritime, each ceiling-valued at $250,000 and running through 2026. These IDCs cover gaskets (NSN 5330015381008), piston rod guides (NSN 3040015126706), door wedges, and related maritime hardware, with standing estimates of three to nine task orders annually. A sixth IDC with DLA Aviation (expired January 2024) previously covered door wedges. Recent representative task orders include $8,000 for gasket delivery against the September 2024–September 2025 IDC (awarded November 2024, due January 2025), $6,150 for gaskets against an earlier IDC (April 2023), and $10,250 for gasket delivery orders (February 2024). Beyond DLA, Mapeco operates under Coast Guard contract vehicles including HSCG4015D60673 (13 task orders, $1.1 million combined potential value). Individual prime purchase orders include a $303,395 Naval Sea Systems Command order for USS Zumwalt (DDG-1000) door bay assembly (September 2023, due October 2024), a $240,900 Naval Supply Systems Command order for a 24-inch by 24-inch watertight hatch (April 2025, due October 2026), and multiple Coast Guard orders for specialized components such as hydraulic cylinder assemblies and locking cylinders valued in the $16,500 to $224,400 range.

Product portfolio spans fasteners (pins, screws, bolts, rivets, washers, nuts), seals and gaskets (metallic and nonmetallic), mechanical transmission components (gears, shafts, spindles, pumps), watertight and marine hardware (doors, hatches, hinges, wear plates, cylinders, dog assemblies), and emergency equipment (signal horns, hand pumps, tire assemblies). Top NAICS concentrations are Bolt, Nut, Screw, Rivet, and Washer Manufacturing (143 awards), Fabricated Structural Metal Manufacturing (95 awards), and Mechanical Power Transmission Equipment Manufacturing (86 awards). Top PSC categories include Packing and Gasket Materials (108 awards), Miscellaneous Power Transmission Equipment (100 awards), and Marine Hardware and Hull Items (98 awards).

Mapeco operates as a subcontractor to major defense primes on naval vessel modernization and new-construction programs. Named subcontract relationships include Huntington Ingalls Incorporated (DDG 1000/1001 modernization, including gaskets and watertight doors; LPD 17 class door components; NSC warranty and NCR work), KBR Services LLC (Marine Corps Prepositioning Program hinged hatches in Norway and Navy sustainment services), Marinette Marine Corporation (FFG(X) frigate construction hatch detail design), and BAE Systems Land & Armaments (material support for armored vehicle components). Marine Hydraulics International LLC engaged Mapeco for onsite technical representative support for flight deck ramp door repairs on USS Mesa Verde (LPD 19). Sub-award activity is minimal by count (21 awards, 2% of total portfolio) but strategically aligned with naval shipbuilding and sustainment programs.

Service Contract Inventory coverage is negligible — one FY2025 SCI record as a named subcontractor, 0.1 FTEs — reflecting Mapeco's business model as a goods manufacturer rather than a services provider. The SCI dataset captures service labor only and excludes the product-delivery work that constitutes the overwhelming majority of Mapeco's federal revenue.

Activity has contracted year over year from a peak of 122 awards in 2022 to 33 awards in 2026 year-to-date. No recompete cliff is evident in the source; the vendor's DLA IDC vehicles expire in 2026 and will likely roll to new awards or renewal competitions. Mapeco competes full-and-open with no active SBA set-asides or small-business designations, positioning the vendor as a mainstream industrial supplier to defense logistics and maritime customers rather than a set-aside beneficiary.
