Pemko S44BL18 216" 18' SiliconSeal Adhesive Backed Fire and Smoke Gasketing Black Finish

The S44BL18 silicone perimeter gasket seals fire and smoke doors in commercial buildings where tight frames require low closing force. Installed around door frames, this adhesive-backed gasketing compresses to seal gaps as small as 1/16" while maintaining compliance with fire door and smoke control requirements. Pemko designed this extruded silicone gasket for applications where traditional gasketing creates excessive door resistance.

The high-temperature silicone construction resists extreme conditions while providing reliable sealing performance. The adhesive backing simplifies installation without mounting hardware. At 216 inches, this coil length suits most standard door applications in office buildings, healthcare facilities, and educational institutions.

This gasket meets UL 10C fire testing standards and UL 1784 air leakage requirements for smoke control assemblies. It also complies with ANSI/BHMA A156.22 door gasketing standards and ASTM E283 air infiltration testing. Fire door assemblies using this gasketing must undergo UL 10C positive pressure testing to maintain their fire ratings. For broader code context on door hardware integration, see ANSI A156.4 door closer requirements that work with low-force gasketing systems.
