#3 Dektite Dark Blue Round EPDM Pipe Flashing – DF103DB

The #3 Dektite Dark Blue Round EPDM Pipe Flashing (DF103DB) is engineered to provide a durable, watertight seal around pipe penetrations on metal roofing systems. Manufactured from premium dark blue EPDM rubber, this one-piece flashing offers outstanding resistance to UV exposure, ozone, weathering, and extreme temperatures, making it an excellent choice for long-lasting residential, commercial, agricultural, and industrial roofing applications. The flexible aluminum base easily conforms to a variety of metal roof profiles, creating a secure, leak-resistant seal.

Designed to fit pipe outside diameters from 1/4" to 5" (5–127 mm), the pleated cone features molded cutting guides for accurate sizing and easy installation. Its flexible design accommodates roof pitches from 0° to 40° (up to a 10/12 pitch) while allowing for normal thermal expansion and contraction without compromising the weatherproof seal. The DF103DB is ideal for plumbing vents, HVAC penetrations, and electrical conduit installations on metal roofs.
