Piping Penetration Seal Bellows

Piping penetration bellows are engineered covers designed to seal around process pipes as they pass through walls, floors, and roofs. These flexible boots help maintain pressure differentials between rooms and prevent air and water leakage. Their durable construction allows for both lateral and axial pipe movement, making them ideal for dynamic applications. With proven expertise in demanding environments, Dynatect is the trusted provider of piping penetration seals for nuclear and conventional power plants, chemical facilities, and refineries.

Product Details

Construction/Functionality

Manufactured of durable, elastomer-coated fabrics, these seals allow lateral and axial movement of pipes up to several inches. Both bellows type and cone shaped seals have a zipper option that permits easy installation after piping has been installed. Zippered units have an air flap seal which overlaps the zipper and may be sealed with silicone for additional sealing.
