Carlisle Hardcast 309991 Pipe Seal Flashing 1-6 in

Product Description

The CARLISLE HARDCAST 309991 is a pipe seal pipe flashing designed to create a weathertight seal around pipes that penetrate roofing and wall assemblies. It accommodates pipe diameters ranging from 1 to 6 inches, making it a versatile single-unit solution for a range of pipe sizes encountered on the job. Licensed roofers, plumbers, and general contractors install this type of flashing during new construction and re-roofing projects to prevent water intrusion at pipe penetration points. The 309991 weighs 1 pound, keeping it easy to handle and position during installation.

This pipe seal flashing is suited for use on residential and light commercial roofing applications wherever pipes pass through the roof deck or wall assembly. Typical installations include plumbing vent stacks, conduit penetrations, and gas service lines. Its 1 to 6 inch pipe range covers the majority of common penetration diameters, reducing the need to stock multiple flashing sizes for standard service calls.

Installation Notes

Pipe seal flashings of this type are installed by licensed roofers or plumbers following applicable local building codes and manufacturer guidelines. Before installation, ensure the pipe and surrounding deck surface are clean, dry, and free of debris. Follow the roofing system manufacturer's recommended adhesive or fastening method to secure the flashing base and create a continuous seal. Avoid stretching the flashing boot beyond its rated pipe diameter range, as doing so may compromise the seal integrity.
