Product Information
Full details
The ClassicBond EPDM Pressure Sensitive Pipe Seal is an essential component for professional roofers and DIY enthusiasts needing a reliable, watertight finish around roof penetrations. Designed for pipes between 25mm and 150mm in diameter, this pre-moulded flashing provides a durable, long-lasting seal that withstands harsh weather conditions; however, it is critical to note that users must purchase the ClassicBond EPDM Primer separately to ensure the necessary adhesion for a successful installation.

FAQs
Does this seal fit pipes larger than 150mm?
No, this specific model is designed for pipe diameters between 25mm and 150mm.
Is the primer included in the box?
No, the ClassicBond EPDM Primer (302060) is sold separately and is required for installation.
Can I use this on a non-EPDM roof?
This product is specifically designed for use with EPDM roofing systems. Compatibility with other materials should be verified with the manufacturer.
What tools do I need for installation?
You will need a sharp utility knife for cutting the collar, a cleaning agent for the surface, and a screwdriver or nut driver for the clamping ring.
How do I ensure the cut on the collar is accurate?
The collar is ribbed with markings; carefully follow the specific line that corresponds to your pipe's measured diameter.
Troubleshooting
The seal is not sticking properly to the EPDM membrane.
Ensure the surface was thoroughly cleaned and that ClassicBond EPDM Primer was applied to both surfaces before bonding.
Water is leaking through the top of the collar.
Verify that the stainless steel clamping ring is properly tightened and that the collar was cut to the correct, snug diameter.

Setup, Compatibility & Care
For optimal performance, ensure the roof surface is clean, dry, and free of debris before beginning. The most vital step in the setup process is the application of ClassicBond EPDM Primer (302060) to both the roof membrane and the underside of the pipe seal base; without this primer, the seam tape will not achieve the necessary bond strength. When cutting the ribbed collar, use a sharp utility knife and ensure the cut is smooth to prevent tearing. For long-term care, perform annual inspections of the clamping ring to ensure it remains tight and check the seal for any signs of physical damage or debris buildup around the base.
