Pemko PK55BL Silicone Seal Perimeter Fire/Smoke Gasketing - Black
The Pemko PK55BL is an architectural-grade Adhesive-Backed Perimeter Seal engineered for critical fire and smoke containment. Manufactured from high-performance PemkoPrene®, this gasket is specifically designed for tighter door frames where a standard bulb seal might interfere with door latching or closing. It provides an exceptional barrier against smoke, air, and weather, while its Black finish offers a clean, contemporary aesthetic that complements modern commercial hardware.
High-Performance & Durability Features
- Extreme Temperature Resilience: Stays flexible in environments ranging from -40°F to 250°F with high resistance to flex fatigue, ensuring the seal remains pliable and effective for years.
- Low Closing Force: Engineered to begin compressing at 3/16" and seal gaps down to 1/16", providing a high-performance seal without making the door difficult to operate.
- Superior Environmental Resistance: Boasts an outstanding ozone resistance rating and is impervious to UV rays, preventing the cracking or degradation common in lower-quality vinyl seals.
- Compression Set Recovery: Features excellent resistance to compression set, meaning the material returns to its original shape even after being compressed for long periods of time.
- Life Safety & Fire Certified: Fully tested under UL 10C (Fire) and UL 1784 (Smoke). It meets Category H and J requirements for steel frames rated up to 3 hours and wood doors up to 90 minutes.

Pro-Tip for Facility Managers
The Pemko PK55BL is the ideal "low-profile" solution for high-traffic commercial doors that must meet strict NFPA 105 smoke assembly standards. To ensure a professional, long-lasting bond, the frame header and jambs must be cleaned with an alcohol-based cleaner to remove grease and dust before application. This ensures the gasket remains firmly anchored during the heavy cycles of a busy commercial entrance.
