PSP SEALS LLC

PSP SEALS LLC specializes in the design, manufacture, and supply of precision gaskets, packings, and sealing devices for mission-critical defense and industrial applications. Their technical expertise centers on high-performance elastomeric and metallic sealing solutions, including custom packing assemblies and pressure-retaining components used in aerospace, ground vehicle, and ordnance systems. The company demonstrates deep proficiency in material selection for extreme environments—such as thermal cycling, chemical exposure, and high-vibration conditions—ensuring leak-tight integrity in military-grade hardware. Their capability extends to precision fabrication of related fastener systems and wire-formed components, supporting complex assemblies requiring tight dimensional tolerances and repeatable performance under load. The contractor maintains a consistent and primary relationship with the Department of Defense, delivering sealed components for propulsion systems, hydraulic assemblies, and ordnance interfaces. Their work for DLA Land and Maritime focuses on standardized NSN-managed sealing parts, often under indefinite delivery contracts requiring rapid replenishment and logistics readiness. These engagements reflect a trusted supply chain role in sustaining fleet readiness across land and maritime platforms. Industry focus is firmly anchored in NAICS 339991, where they produce engineered sealing solutions for defense and industrial machinery, with supplementary experience in bolted joint systems, rubber hose assemblies, and valve components. Their market positioning is that of a niche, high-reliability supplier for systems requiring zero-failure sealing performance, particularly in applications where failure could compromise safety or operational continuity. PSP SEALS LLC is a small business based in Fort Wayne, Indiana, operating as a 2K entity with no active government certifications. Their geographic footprint is localized, but their supply chain integration with DoD logistics networks positions them as a dependable source for critical sealing components within the defense industrial base.
