Panduit XG-FSK7 FlexFusion Door Seal Kit 700mm

Panduit XG-FSK7 FlexFusion Front/Rear Door Sealing Kit

Air bypass around cabinet doors undermines hot-aisle/cold-aisle containment strategies, forcing CRAC units to overcool and driving up operational costs. The Panduit XG-FSK7 door sealing kit eliminates gaps at the perimeter of 700mm-wide FlexFusion cabinet doors, creating a compression seal that reduces recirculation between supply and return plenums. Designed for data centers running active containment systems, this kit ships with front and rear door gaskets, adhesive-backed for fast retrofit or new-build installation. RoHS-compliant black construction matches FlexFusion aesthetics while meeting environmental directives for IT infrastructure.

Key Features

• 700mm Cabinet Compatibility: Pre-cut gasket lengths sized specifically for Panduit FlexFusion 700mm-wide cabinets—no field trimming required
• Front & Rear Coverage: Includes sealing material for both cabinet doors, addressing bypass at all vertical edges and top/bottom interfaces
• Adhesive-Backed Installation: Peel-and-stick application bonds to door frames in minutes, eliminating mechanical fasteners and cabinet modifications
• Hot/Cold Aisle Optimization: Closes air gaps that short-circuit containment systems, improving delta-T across cooling coils and reducing fan energy
• RoHS Compliant: Meets EU Directive 2011/65/EU for restricted substances, required for projects under green building certifications or European deployments

The XG-FSK7 uses a closed-cell foam elastomer that compresses under door closure to form a continuous seal around the cabinet perimeter. Material thickness is calibrated to accommodate typical door-to-frame tolerances in FlexFusion enclosures without interfering with latch mechanisms or requiring hinge adjustments. The adhesive backing uses a high-bond acrylic formulation that adheres to powder-coated steel surfaces common in cabinet construction, maintaining hold through repeated thermal cycling in 18–27°C data center environments. Installers clean the door frame with isopropyl alcohol, remove the backing liner, and press the gasket into place along the marked application zones—total install time per cabinet is under 10 minutes. The kit ships as a single package containing pre-cut sections for one complete cabinet (front and rear doors), with excess material for field adjustments if doors have been modified or non-standard latches installed.

Deploy the XG-FSK7 when commissioning new containment corridors or retrofitting existing racks that show elevated mixed-air temperatures at the cabinet face. Thermal imaging surveys often reveal air bypass around door edges as hot spots in cold aisles or cold intrusion in hot aisles—sealing kits address this without the cost of replacing entire door assemblies. In hyperscale or colocation environments running variable-speed CRAC systems, closing these leaks allows controls to reduce airflow rates while maintaining target supply temperatures, directly cutting fan power consumption. The sealing kit pairs with Panduit's cabinet blanking panels and brush strips for a complete air-management retrofit: blanking panels block unused rack units, brush strips seal cable-entry points, and door seals eliminate perimeter bypass. For projects pursuing ASHRAE 90.4 compliance or LEED data center credits, documented air-containment measures—including door seals—support energy-efficiency narratives in commissioning reports. Black coloration ensures the gaskets remain visually unobtrusive on FlexFusion's black-frame cabinets, critical in customer-facing colocation suites or executive data center tours where aesthetic consistency is a deployment requirement.

RoHS compliance certifies that the foam and adhesive formulations contain no lead, mercury, cadmium, hexavalent chromium, or restricted flame retardants, aligning with procurement policies at organizations under EU regulations or voluntary green IT initiatives. The single-pack format (one kit per cabinet) simplifies ordering for large deployments—procurement teams multiply cabinet count by one to determine total kits required, avoiding over-ordering or partial-kit waste. Field-proven in Panduit FlexFusion installations across enterprise, hyperscale, and edge data centers, the XG-FSK7 delivers measurable thermal performance improvements through a simple, low-cost retrofit that integrates directly with existing cabinet hardware.
