Features twenty (20) integrated clearance through-holes designed to accept standard 5/16\" high-tensile fasteners on a standard bolt circle diameter. This configuration allows standard pass-through bolting against matching clearance-hole or tapped vacuum chamber ports, providing maximum versatility across multi-flange structural manifold stacks. 02 Bore Specification: 6.75\" Nominal ID (Weld-Neck Clearance Sleeve) The center bore is precision-machined to exactly 6.75 inches (171.45 mm / 6-3/4\") ID, purposely engineered to serve as a slip-fit weld socket over standard 6-inch Schedule 5S or Schedule 10S industrial stainless steel piping (which carries a true 6.625\" OD). This smooth profile eliminates internal structural pockets or mechanical dead zones, maximizing molecular gas conductance and fundamentally blocking virtual leaks or process gas turbulence. Engineered specifically for heavy-walled industrial processing lines where thin-walled fractional tubing would fail under extreme atmospheric load or high-temperature structural twisting cycles. 03 Forensic Sealing & Through-Hole Audit: Verified USED Excellent Technically audited (Tier 3). The circular 8.0\" ConFlat (DN150CF) sealing ridge is sharp, uniform, and completely free of cross-axis radial gouges, deep scratches, tool driver slips, or drop nicks. Faint, uniform concentric installation witness marks are present from a previous installation cycle but sit safely within standard, predictable operational tolerances. Verified to create an immediate, airtight metal-to-metal copper gasket cold weld. All 20 through-holes have been checked for roundness, lack of burs, and structural warping.

BLUE DIAMOND INTEGRITY CLAUSE: This premium pristine 8.0\" ConFlat vacuum hardware node qualifies for Free 30-Day Domestic Returns. In accordance with platform-standard seller protection guidelines, any returned asset must arrive back at our facility in its identical shipped baseline state. Since this item is listed in excellent used condition, the opening of cleanroom protective bags, the introduction of new knife-edge damage signatures (such as driver tool slips, radial scratches, edge flattening, or dropped dents), or chemical/atmospheric grease contamination from exposure to unvetted laboratory lines will result in an immediate, mandatory 50% refund deduction due to the total loss of technical utility and uninstalled industrial resale value.
