The DEKS Flat Seal PVC is designed to provide a reliable and watertight seal around pipe penetrations on flat roofs using PVC membrane systems. Ideal for sealing around service pipes, ventilation outlets and other roof penetrations, this flashing ensures a secure connection between the pipe and roofing membrane.
Featuring a flexible EPDM sealing cone, the flat seal offers excellent elasticity and long-term resistance to weathering, UV exposure and temperature fluctuations. The smooth PVC-compatible flange allows thermal welding directly to PVC membranes, creating a strong and durable bond.
The conical design includes pre-formed cutting grooves, allowing the seal to be trimmed precisely to suit a wide range of pipe diameters. Available in two size ranges, this flat seal is suitable for both small and large pipe penetrations across residential and commercial flat roofing applications.
Key Benefits
• Designed for use with PVC roofing membranes
• Smooth flange allows heat welding to membrane systems
• Flexible EPDM cone provides long-term durability and performance
• Pre-formed cutting grooves allow easy sizing to pipe diameter
• Provides a secure and watertight seal around pipe penetrations
