Clark-Reliance LLC

Clark-Reliance LLC, doing business as Jacoby-Tarbox, manufactures precision industrial components—liquid sight indicators, gaskets, packing retainers, nonmetallic tubing, and related mechanical parts—and sells them as a prime contractor to the Department of Defense on purchase orders without set-aside designation or under small business set-asides.

The company is a for-profit manufacturer headquartered in Strongsville, Ohio, with a federal contracting history dating to January 1998. Clark-Reliance LLC operates through multiple subsidiaries and trade names including Jerguson Gage & Valve and Jacoby Tarbox Co., positioning itself as a specialized supplier to defense logistics and naval operations. Recent awards include a $111,860 firm fixed-price Competitive Small Business purchase order from Defense Logistics Agency Aviation on June 30, 2025, for 28 units of liquid sight indicators, a $36,000 firm fixed-price order from DLA Land and Maritime on September 12, 2023, for packing services, and a $33,465 firm fixed-price order from DLA Land and Maritime on March 10, 2025, for packing retainers. The company competes both full-and-open and under Total Small Business set-asides; of 31 recent prime awards, 11 carried small business set-aside designations and 20 were awarded full-and-open.

Customer concentration is heavily weighted to Defense Logistics Agency divisional activities. DLA Aviation dominates both volume and dollars, accounting for 15 awards carrying $261 thousand in combined potential value. DLA Land and Maritime follows with 9 awards ($109 thousand), while Department of the Navy Naval Sea Systems Command contributes 4 awards ($45 thousand). Together these three customer entities represent 100% of the award portfolio across 28 of 31 prime awards. The remaining two customers—DLA Construction and Equipment and Naval Supply Systems Command—account for three awards totaling $25 thousand. All five agencies rank identically on award count and potential value, reflecting the portfolio's consistency: small to mid-five-figure purchase orders with no concentration distortion between volume and dollar metrics.

Clark-Reliance LLC performs work at its Strongsville, Ohio headquarters and at subordinate locations including Portsmouth, Virginia for Naval Supply Systems Command deliveries. All 31 awards are purchase orders with firm fixed pricing; the company has not competed on IDIQs, GWACs, or BPAs. Activity has grown substantially—5 awards in 2023, 7 in 2024, 18 in 2025, and 1 in 2026—though the portfolio remains sub-$500 thousand in annual run-rate. The company operates exclusively as a prime contractor; no subcontract work appears in the source. Product line concentration follows NAICS and PSC coding: gasket, packing, and sealing device manufacturing accounts for 7 awards; instruments and process-control devices account for 6 awards; measuring and controlling devices account for 5 awards; bolts, nuts, screws, and washers account for 4 awards. By PSC, liquid and gas flow and liquid-level measuring instruments dominate at 15 awards, followed by packing and gasket materials at 8 awards.
