Product details

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.

Improved grouted connection. Helps improve the seal where pipe passes through a concrete manhole or similar structure.

Better interface for difficult surfaces. Useful where concrete will not adhere directly to the pipe, including plastic pipe.

Flexible fit. 4CMA has a 4.10 in. ID and fits pipe ODs from 4.20 in. to 4.50 in.
