Engineered Seal Products Inc.

Engineered Seal Products Inc., doing business as ESP International, manufactures and distributes o-rings, preformed packing materials, gaskets, and other custom-engineered sealing components to the U.S. Department of Defense as a prime contractor operating exclusively in full-and-open and total small business set-aside competitions. ESP International is a for-profit Subchapter S Corporation headquartered in Cedar Rapids, Iowa, with SAM registration dating to 2002 and over fifty years of operational history supplying military sealing solutions.

The vendor's federal footprint concentrates almost exclusively with the Defense Logistics Agency. The Defense Logistics Agency Land and Maritime accounts for 461 of 480 total awards (96% of volume) and $5.1 million of $5.2 million combined potential value across the tracked award population. DLA Aviation holds thirteen awards valued at $17 thousand, while the Army Materiel Command's TACOM Life Cycle Management Command, DLA Troop Support Hardware, and the Department of the Army account for the remaining six awards. The concentration is extreme: one customer funds over 98% of ESP International's federal contracting activity.

Capability framing flows directly from the award record. ESP International's work centers on o-ring procurement (407 awards) and packing and gasket materials (68 awards), with smaller volumes in fabricated wire products, engine parts, bolts, and hoses. Representative named contracts include a $79,000 purchase order from DLA Land and Maritime for o-rings (September 2023), a $6,421.60 purchase order for o-rings under NSN 8510396708 (January 2024), a $57,084 total small business set-aside purchase order from DLA Aviation for packing with retain items (December 2023), and a $2,709.03 purchase order from DLA Land and Maritime for o-rings (January 2026). The vast majority of awards fall in the $50 to $10,000 range, reflecting DLA's procurement pattern for consumable seal components.

ESP International holds seven active Indefinite Delivery Contracts with DLA Land and Maritime, each capped at $250,000 and designated as either total small business set-asides or full-and-open. These IDCs carry completion dates extending through September 2025 and serve as the parent vehicles against which DLA places the bulk of task orders. The contracts cover multiple National Stock Numbers for o-rings, preformed packing materials, and packing with retainers, with guaranteed minimum quantities and estimated order frequencies (typically 1–12 orders per year per IDC). Recent task orders under these vehicles include delivery orders valued at $2,483.46 and $2,978.40 for preformed packing and o-rings respectively.

Activity trajectory shows contraction. The source data spans twenty-seven years and records 480 awards across that period, but award velocity has declined sharply: 259 awards in 2022, 164 in 2023, 31 in 2024, 20 in 2025, and one in 2026. This pattern reflects either a shift in DLA's sourcing behavior, consolidation of small orders into fewer larger purchases, or migration of demand to other suppliers. The most recent award dates to January 2026.

ESP International competes exclusively as a prime contractor with no subcontract footprint in the source data. All work is performed at the contractor's Cedar Rapids facility. The vendor does not hold positions on government-wide vehicles such as GWACs or GSA Schedules; activity is confined to DLA-specific IDCs and spot purchase orders. Set-aside posture shows mixed designation: several IDCs carry total small business set-aside markings, while others are full-and-open. A notable September 2025 award carried a total small business set-aside flag, as did December 2023 and December 2023 aviation-sector purchases.

The combined obligated dollars across all tracked awards total $462 thousand against $5.2 million in combined potential value, implying that most of ESP International's awarded work remains unfulfilled or only partially billed at the time of source capture. This low invoke rate is consistent with the vendor's role as a supply-on-demand partner for consumable parts under indefinite delivery vehicles.
