4TAS LLC

4TAS LLC specializes in the precision manufacturing of mission-critical mechanical components for defense and federal systems, with deep expertise in sealing, fluid power, and mechanical actuation systems. The company produces high-integrity gaskets, O-rings, valve seats, pump units, and bearing assemblies that meet stringent military and industrial performance standards. Their technical capabilities span the design and fabrication of sealing devices, industrial valves, fluid power pumps, and fabricated wire products, all engineered for durability under extreme pressure, temperature, and vibration environments. A notable specialization lies in custom-engineered components for aerospace and defense applications, including aircraft gaskets and hydraulic system parts, demonstrating a strong grasp of materials science and tight-tolerance manufacturing processes. The contractor maintains a consistent relationship with the Department of Defense, supplying components essential to naval, ground, and aerospace platforms. Their work supports maintenance, repair, and overhaul operations, delivering replacement and upgrade parts that ensure operational readiness across weapon systems, vehicles, and aircraft. The single GSA contract indicates engagement in broader federal supply chain logistics, likely through schedule-based procurement channels for standardized industrial hardware. 4TAS LLC’s primary industry focus is on mechanical component manufacturing, particularly in gasket and sealing device production, fluid power systems, and industrial valve fabrication. These NAICS categories reflect a niche positioning as a supplier of mission-essential parts for ruggedized equipment, serving defense, aerospace, and heavy industrial markets. Their product portfolio suggests specialization in replacing legacy components with certified, fit-for-purpose alternatives. As a small business structured as 2K and headquartered in Richmond, Virginia, 4TAS LLC operates without federal certifications but maintains a focused presence in the defense supply chain. Their geographic location supports access to East Coast defense contractors and logistics hubs, enabling responsive delivery to military depots and maintenance facilities.
