What Russtech Engineering does
Russtech Engineering, Inc. is a privately held, family-owned precision manufacturer founded in 1974 by Russell Fieberg and currently led by his son Don Fieberg. The company designs, manufactures, and sells aerospace-grade interconnect accessories and connector assembly tooling through four product families: the inFlite family of glass-filled Ultem (PEI) composite EMI backshells and slide latches for D-Sub and EN4165 connectors; the microFlite family of Micro-D backshells and Molex strain reliefs; the preFlite family of contact retention test tools, positive insertion tools, and calibration verification equipment; and the ENiX adaptor system bridging EN4165 with iX industrial connectors. Manufacturing is performed in-house via CNC milling, injection molding, and additive manufacturing at a Mukilteo, WA headquarters that consolidated from the prior Irvine, CA footprint in 2021, with an engineering support office in Everett, WA and global reach provided through an authorized distributor (Air Cost Control) plus three U.S. field sales representatives.
The company's revenue model is hardware-led with a thin layer of systems engineering and Value Methodology consulting services. Products are predominantly one-off hardware sales priced via quote, with replacement parts, calibration verification tools, and consumable probes generating recurring aftermarket revenue. Distribution combines direct field sales (Northeast, Midwest, and Southeast U.S. manufacturing reps), an authorized global distributor for backshell families, a regional distributor for tooling, and quote-based direct engagement via the website. Customers are aerospace OEMs, Tier 1 suppliers, defense/military primes, and MRO operators, with historical marquee relationships including Boeing (Top Tier Supplier 2007–2019), a major aircraft OEM selected in 1985 to replace an incumbent, and NASA's International Space Station program.
Qualification is the central commercial asset: Russtech holds AS9100D (re-issued June 18, 2025, certificate #22896), ISO 9001:2015, ISO 14001:2015, FAA Parts Manufacturer Approval, and RoHS/REACH compliance, and its products exceed DO-160 shock and vibration and meet FAR 25.853 smoke/flammability/toxicity requirements. The company also holds U.S. Patent No. 4,028,812 (1977) for its foundational Contact Retention Test Tool and claims proprietary EMI composite chemistry as a structural technology moat. The business is conservatively financed: no outside funding rounds are disclosed, ownership remains concentrated within the Fieberg family, and the company operates with 11–50 employees across two Washington state locations.
