About Grayloc Products, L.l.c
Grayloc Products, L.l.c, a Houston, Texas-based manufacturer of metal-to-metal bore seal technology and hydraulic connection systems, operates as a subsidiary of Oceaneering International Inc. and sells specialized fittings, seals, clamps, and gaskets to federal agencies as a prime contractor on purchase orders (87% of recent awards) and as a subcontractor to defense primes. The vendor competes full-and-open across all award categories with no set-aside designations in its federal footprint.
Grayloc's capability portfolio centers on precision-engineered seal rings, reflange fittings, high-temperature gaskets, and clamp assemblies for mission-critical applications in naval propulsion, aerospace, and munitions programs. Representative prime work includes a $176,692 purchase order from the Air Force Research Laboratory for Grayloc hubs, seals, and clamps supporting the Materiel Research and Evaluation Team (December 2021); a $30,205 delivery of replacement high-temperature gaskets for Grayloc reflange fittings to the NASA Shared Services Center (August 2022); and two recent seal ring purchase orders from Naval Sea Systems Command (February 2026, completion dates May 2026). Recent sub activity routes through Fluor Marine Propulsion, LLC on Naval Nuclear Laboratory and Naval Nuclear Propulsion Program support (January 2026 and August 2025 awards for Grayloc hardware and ion exchange fittings), and through Syncom Space Services LLC on Space Force BE-4 fabrication and installation materials (February 2024).
Customer concentration splits between Navy dominance on volume and Army on dollar value. Naval Sea Systems Command leads by award count (13 awards, $61 thousand combined potential value), while the Department of the Army Materiel Command's Chemical Materials Agency and Joint Munitions Command anchor the largest contracts ($1.6 million and $1.4 million respectively across five awards combined). The top five customer organizations account for 60% of awards and 92% of combined potential value. Grayloc places task orders under an Indefinite Delivery Contract (NNS15AA01C) with the Navy and under Army IDIQ W52P1J09G0005 ($1.4 million combined potential value across two task orders). The vendor's NAICS concentration skews toward miscellaneous fabricated metal product manufacturing (19 awards) and gasket, packing, and sealing device manufacturing (9 awards), with PSC work split across packing and gasket materials, chemical weapons equipment, vehicular components, and hose/pipe fittings. Activity has remained sparse and episodic — two awards per year in 2022–2024, one in 2025, and three in early 2026 — yielding $4.7 million in combined potential value across forty-seven awards since 2004. Obligated dollars have exceeded potential value ($5.1 million obligated against $4.7 million ceiling), signaling frequent contract modifications and expansions against existing order vehicles.
