Transdigm Inc.

Transdigm Inc. Adelwiggins Group Division, doing business as Adel Wiggins Group-Preece, manufactures specialized fluid transfer components and aerospace hardware for the Department of Defense as a prime contractor on firm fixed-price purchase orders, with 92% of recent awards as prime and 8% as subcontractor work. The division is a for-profit manufacturer of goods and a child entity of publicly traded Transdigm Group Incorporated, headquartered in Commerce, California, with operations at East Los Angeles, California and no SBA set-aside designations across its prime footprint—all awards compete on an unrestricted basis.

Adelwiggins Group's capability portfolio centers on quick disconnect couplings, nonmetallic hose assemblies, metal tube assemblies, swivel joints, and related fluid transfer equipment for military platforms. Representative prime work includes a $218.5 thousand DLA Aviation purchase order for 49 coupling half quick disconnect components (August 2025), a $208.3 thousand DLA Land and Maritime order for 39 metal tube assemblies (September 2025), and a $184.7 thousand DLA Land and Maritime order for 90 quick disconnect coupling halves (February 2025). The division also supplies specialized components such as fuel cap assemblies, tube caps, safety relief valves, and protective dust caps. Across product lines, work spans NAICS 326122 (Plastics Pipe and Pipe Fitting Manufacturing), NAICS 332996 (Fabricated Pipe and Pipe Fitting Manufacturing), and related fluid systems categories; PSC 47-P dominates (Hose, Pipe, Tube, Lubing, and Railing Fittings across 124 awards).

Customer concentration is extreme and heavily weighted to DLA Land and Maritime. The top five funding agencies account for 97% of awards, led by Defense Logistics Agency Land and Maritime with 180 awards valued at $6.5 million combined potential value. Defense Logistics Agency Aviation accounts for 14 awards at $529 thousand, Naval Sea Systems Command for 19 awards at $415 thousand, the Army's PEO Ground Combat Systems for 4 awards, and the Department of the Navy for 3 awards. DLA Land and Maritime dominates both volume and dollars; this single customer represents 79% of all prime awards and 85% of combined potential value. The division has no presence on multi-award government-wide vehicles or umbrella contracts; all awards flow through individual DLA and Navy purchase orders ranging from under $1 thousand to $237 thousand.

Activity has grown significantly: 32 awards in 2022, declining to 15 in 2023, then rising to 43 in 2024 and 74 in 2025—demonstrating strong momentum in the most recent reporting year. Ten distinct federal customer agencies appear across the portfolio, but DLA Land and Maritime's dominance means competitive and recompete risk is concentrated there. Thirteen awards valued at $472 thousand reach ultimate completion within the next twenty-four months and will face recompete.

In its subcontractor role, Adelwiggins Group supplies fluid quick disconnect couplings and related components to Electric Boat Corporation on Virginia-class and Ohio-class submarine programs (SSBN 826 and SSN 804 construction), to Lockheed Martin on F-35 aircraft long-lead procurement and JASSM/LRASM programs, to BAE Systems Land & Armaments on M109A7/M992A3 self-propelled howitzer production, and to General Dynamics Mission Systems on Navy software engineering services. Sub work reflects the same core capability—fluid transfer components—but channels it through major defense primes rather than direct DLA procurement. The division operates as an established supplier within the defense industrial base, serving as both a direct DLA source and a qualified subcontractor for prime contractors across aviation, maritime, and ground vehicle platforms.
