Cast Iron’s inherently irregular surface along with corrosion & repeated repairs often make it very difficult to properly seal. The Lifetime Tool® EasyFit™ is both incredibly quick & extremely cost effective. Our patented technology includes an 18″ black ASA polymer cap stock for extreme weatherability (over PVC for strength & impact) and a thick-walled coupling. The three flexible seal rings provide stability and prevent the downdraft of sewer gases. The tap in no-glue compression cap provides superior crush resistance against heavy snow loads. Finish the system installation with the Ultimate Pipe Flashing®.
