Product Description
The NAS557-12B is a nonmetallic split grommet manufactured from polyamide per MIL-M-20693 Type 1 specifications. This component protects wires, cables, and tubing where they pass through aircraft panels, bulkheads, and equipment enclosures. The grommet prevents chafing and abrasion damage by creating a smooth, protective barrier around conductor pass-throughs.
Size 12 accommodates specific hole diameters and material thicknesses. Installation follows aircraft maintenance manual procedures, with the split design allowing quick placement around existing wiring without disconnection. Common in cockpit panels, avionics racks, and fuselage structural penetrations.
