Quick Summary
The Department of the Navy, specifically NAVSUP Weapon Systems Support Mechanicsburg, is soliciting proposals for a BALL,SEAT SET for a 1-inch Ball Valve. This opportunity is designated as a Total Small Business Set-Aside. The required material is classified as SPECIAL EMPHASIS due to its use in crucial shipboard systems, necessitating stringent quality control and traceability. Proposals are due by June 25, 2026.
Scope of Work

Seats must be MD71-GG Mearthane (Graphite Filled Urethane) from Mearthane Products Inc., Cranston, RI, meeting specific property values (Hardness, Specific Gravity, Tensile Strength, Compression-Deflection, Tensile Impact, Water Absorption).
- Testing & Certification: Required certifications include Hydrostatic Test (Ball), Dye Penetrant Inspection (Ball), and Non-Destructive Tests (Weld Repair/Production Weld). Detailed pressure and test time tolerances are provided.
