Sure-Flex PVC Split Pipe Seals are fabricated flashings made of 60-mil (1.52 mm) reinforced PVC membrane for pipes. Overall height of the flashing is 11" (280 mm). A split (cut) and overlap tab are incorporated into these parts to allow the Split Pipe Seals to be opened and wrapped around a round pipe with an obstruction. Such obstructions prevent the use of a standard molded pipe seal. Split Pipe Seals are packaged in boxes of eight and come with universal clamping rings. Carlisle's PVC Split Pipe Seals are part of the Certified Fabricated accessory (CFA) program. certified Fabricated Accessories are the only factory-fabricated PVC accessories that meet the stringent quality tolerances required to be included in a Carlisle warranted roofing system.
