Forensic Audit: structural Scaling Intelligence

01
Precision 4.5" to 1.33" Scale Transition Specifically engineered by MDC Precision (Vacuum Products Corp) to facilitate high-integrity reduction from major 4.50-inch OD (DN63) chamber ports to universal 1.33-inch (DN16) mini-conflat diagnostics. Enables the seamless integration of RGAs, leak valves, or diagnostic sensors into primary high-conductance manifolds without the Bolt-Lock constraints of zero-length adapters.
02
4.00" Optimized Axial Standoff (101.6mm) The calibrated 4.00-inch reach provides critical physical and thermal clearance for secondary instrumentation. This axial extension facilitates high-node diagnostic access, ensuring that delicate sensors or viewport electronics remain protected from the heat-flux or mechanical vibration of primary process lines.
03
Forensic Sealing Audit: Verified USED Status Technically audited (Tier 3). Both ConFlat sealing interfaces—the 4.50" (DN63) and 1.33" (DN16)—have been forensically micro-vetted under 10x magnification. Sealing knife-edges are verified **sharp and free of deep radial scoring**, ensuring absolute metallurgical seal authority. Monolithic 304 Stainless Steel construction is solvent-wiped (IPA) and verified for base pressures reaching the 1 × 10-10 Torr floor. Ready for immediate commission.
