Fernco Concrete Manhole Adapters improve grouted connections where plastic or cast iron pipe passes through a concrete manhole or similar structure. The flexible elastomeric PVC adapter provides an interface between the pipe and grout while permitting lateral pipe movement without destroying seal integrity. Corrosion-proof and unaffected by acids or alkalis, CMAs are suited for sanitary sewer, stormwater and wastewater structures where concrete will not adhere directly to the pipe. Sealing performance depends on grout quality, workmanship, groundwater and field conditions; this product is not warranted as a positive water seal.
