Pemko PK55 PemkoPrene® Adhesive Perimeter Gasket
The Pemko PK55 PemkoPrene® Adhesive Perimeter Gasket is a commercial-grade, self-adhesive seal designed for tighter door frames. Additionally, it features extremely low closing force, allowing doors to close smoothly while maintaining a reliable seal against smoke, fire, air, sound, and weather. Because the gasket begins compressing at 3/16″ and seals gaps up to 1/16″, it provides precise, long-lasting protection for fire-rated door assemblies.
Moreover, the PK55 is made from high-temperature PemkoPrene® material, which is self-extinguishing, non-toxic, and resistant to sunlight, ozone, and UV exposure. In fact, it is impervious to fungus and mildew, ensuring durability in commercial environments. Furthermore, it is easy to install with its self-adhesive backing and can be applied to the top and sides of steel, composite, and wood fire doors.
