This opportunity involves procuring adapters for maintenance and installation activities at Norfolk Naval Shipyard in Portsmouth, VA, with materials only—no installation services required. The requirement is a sole-source acquisition from Dibert Valve & Fitting Co., Inc., as the authorized distributor of SWAGELOK equipment, since the parts are direct replacements for existing shipyard equipment and must match OEM specifications to avoid malfunctions. The award will be a Firm-Fixed-Price (FFP) contract, and no substitutes are allowed. Quotes must be all-inclusive, covering shipping and all associated costs, with no additional charges accepted after award. No budget amounts or submission timelines are specified in the description.
