Puddle Flanges

Fiber Glass System’s Pipex puddle flanges are suitable for casting into concrete blocks, walls and slabs, providing cable and service penetration points specific to individual project specifications.

Available in standard or bespoke sizes, our unique offsite manufacturing capabilities ensure we can fabricate to any size, diameter or configuration required, with multiple cable entry points and optional bell mouth entries.

Connections can be plain end, or we can supply them complete with machined connectors or double “o” ring sockets to suit the incoming cable/service duct system.

Our puddle flanges are engineered from robust, corrosion resistant thermoplastics with an embossed impregnated surface finish for bonding to concrete structures.
