Concrete Manhole Adapters
Improve grouted connections between plastic or cast iron pipe and concrete manholes or similar structures.
A Better Interface Between Pipe and Concrete
Designed for grouted pipe penetrations where concrete may not adhere directly to the connecting pipe.
Fernco Concrete Manhole Adapters provide an interface between plastic or cast iron pipe and the grout surrounding a concrete structure penetration.
Their flexible construction permits lateral pipe movement without destroying seal integrity, helping the connection accommodate movement commonly encountered in underground piping systems.
Built for Grouted Pipe Penetrations
A practical solution for improving connections where plastic or cast iron pipe enters a concrete manhole or similar structure.
Improves Grouted Connections
Helps improve the connection where pipe passes through the wall of a concrete manhole or similar structure.
Accommodates Pipe Movement
Flexible construction permits lateral pipe movement without destroying seal integrity.
Plastic and Cast Iron Compatible
Designed for plastic and cast iron pipe connections to concrete manholes and similar structures.
Where Concrete Will Not Bond Directly
Concrete Manhole Adapters are particularly useful with smooth plastic pipe, where concrete or grout may not adhere directly to the pipe surface.
