Pemko PK55D Silicone Seal Perimeter Fire/Smoke Gasketing - Dark Brown
The Pemko PK55D 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 operation. It provides an exceptional barrier against smoke, air, and weather, while its Dark Brown finish blends seamlessly into bronze-anodized aluminum or dark wood-grained doors.
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 won't become brittle over time.
- Low Closing Force: Engineered to begin compressing at 3/16" and seal gaps down to 1/16", allowing for a secure seal without making the door difficult to close or latch.
- Superior Environmental Protection: Boasts an outstanding ozone resistance rating and is impervious to UV rays, preventing degradation in sun-exposed exterior or interior openings.
- Compression Set Resistance: Features excellent recovery properties even after being compressed for extended periods, ensuring the gasket maintains its sealing integrity.
- Safety & Life-Safety 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 rated up to 90 minutes.

Pro-Tip for Facility Managers
The Pemko PK55D is the ideal "low-profile" solution for high-traffic commercial doors that must meet strict NFPA 105 smoke assembly standards. For a professional, long-lasting bond, always clean the frame header and jambs with an alcohol-based cleaner to remove grease and dust before applying the pressure-sensitive adhesive. This ensures the gasket remains anchored during the heavy cycles of a busy commercial entrance.
