This is a Justification for Sole Source document supporting a contract award for a Labyrinth Packing Assembly Overhaul Kit (Part Number 571L125-1) valued between $15,000 and $350,000. The procurement is restricted to Curtiss-Wright, the original manufacturer and sole source for this material, as documented under FAR 13.106-1(b).

The justification establishes that Curtiss-Wright is the original equipment manufacturer (OEM) of all GE and Dresser-Rand Government turbines and maintains proprietary rights to all detailed drawings required for the overhaul kit. The document specifies that interchangeability and functionality with installed equipment components must be made using proprietary detail drawings, making substitutes unavailable. The kit comprises internal components of currently installed OEM-designed High Pressure Turbines, with internal components requiring accurate dimensions and specifications per OEM drawings to ensure compatibility and functionality. The material is identified as a direct replacement part for existing brand-name equipment, with proprietary data (DWG 571L125 and associated item drawings) limiting competition. The contracting officer is with DLA Weapons Support Puget Sound, with the justification signed by a Mechanical Engineer on 3/5/2026, and an administrative date of 10/16/2025.
