Differential Pressure Instruments, Inc.

Differential Pressure Instruments, Inc., doing business as Differential Pressure Instrument, manufactures and supplies precision differential pressure gauges, calibration services, and related measurement equipment to the U.S. Navy as a prime contractor, competing on an unrestricted basis (no set-aside designation across recent awards) despite holding self-certified small disadvantaged business, veteran-owned small business, and woman-owned small business designations.

The vendor's customer base is almost entirely Navy-concentrated. Naval Sea Systems Command (NAVSEA) dominates the portfolio, accounting for 53 awards worth $487 thousand in combined potential value — 90% of all awards by count and 76% by potential value. The United States Pacific Fleet Forces places the second-largest volume, with 12 awards ($64 thousand), followed by Naval Supply Systems Command (5 awards, $25 thousand) and Naval Air Systems Command (2 awards, $17 thousand). Across 82 total prime awards tracked in the source data, ten distinct Navy commands and offices have issued purchase orders; the top five account for 96% of combined potential value.

Differential Pressure Instruments manufactures differential pressure gauges — predominantly ITT Barton models across various ranges (0-200 inches H2O, 0-220 inches H2O, and others) with stainless steel housings and bellows — and delivers calibration and repair services for pressure measurement equipment. Representative work includes a $25,158 firm fixed-price purchase order from NAVSEA in February 2025 for six ITT Barton Model 288C differential pressure gauges (0-220 inches H2O, 1% accuracy) supporting the Trident Refit Facility in Kings Bay, Georgia; a $12,455 Total Small Business set-aside purchase order from NAVSEA in May 2025 for differential pressure gauges; and a $6,439 purchase order from NAVSEA in April 2026 for a Barton Model 227C differential pressure gage (0-200 inches H2O, 1/2% accuracy, 316 stainless steel housing). The vendor also provides repair services for Barton pressure gauges, as evidenced by a $5,579 December 2024 purchase order from NAVSEA.

The vendor's primary NAICS category is Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables (56 awards), with secondary exposure in Totalizing Fluid Meter and Counting Device Manufacturing (7 awards). Top PSC categories align: Pressure, Temperature, and Humidity Measuring and Controlling Instruments (37 awards) and Liquid and Gas Flow, Liquid Level, and Mechanical Motion Measuring Instruments (26 awards).

Activity has been modest but steady, with two awards in 2021, two in 2023, one in 2024, four in 2025, and two in 2026 (through April). The combined potential value across all 82 awards is $635 thousand, with $667 thousand obligated to date, indicating that invoiced delivery has exceeded the stated ceiling by 5 percent. Only two awards carry ultimate completion dates inside the next twenty-four months, totaling $13 thousand in recompete exposure. The vendor operates as a 100% prime contractor with no subcontract footprint in the source data.
