The Rectangular Pipe to Round Connector provides a transition fitting between a cast iron rectangular downpipe and a cast iron round downpipe, allowing the two pipe systems to be joined cleanly in a single run. Used where a rectangular pipe at the upper part of the elevation transitions to a round pipe — for example where the rectangular section connects to a round underground drainage system, or where an existing round pipe is being connected to a new rectangular installation above.

An important practical fitting on heritage restoration projects where the existing above-ground pipe is rectangular and the below-ground or transition pipework is round. Manufactured in cast iron to BS 460:2002. Available in sizes to suit the standard rectangular pipe range. For specification support, call 0333 987 4452.

What pipe connection sizes do your cast iron hopper heads accept?

What paint finish should I use on cast iron guttering?

What paint finish should I use on cast iron guttering?

Linseed oil paint is the most appropriate finish for cast iron guttering on listed and historic buildings. It is breathable, flexible, and penetrating — qualities that suit the movement characteristics of cast iron through seasonal temperature changes. Tuscan Foundry Products offers a curated range of heritage linseed oil colours. For modern applications, a high-quality exterior oil-based paint system over a metal primer is also acceptable.

What is BS 460:2002?

What is BS 460:2002?

BS 460:2002 is the British Standard governing cast iron rainwater goods — gutters, pipes, and fittings. It sets the dimensional tolerances, materials, and performance requirements a component must meet, so that joints seal, sections align, and the system performs as a whole rather than as isolated parts. All Tuscan Foundry Products components are manufactured to comply with BS 460:2002, which is worth citing directly in specification documents and listed building consent applications. The same manufacturing standard applies to bespoke and copy-cast work, even where the profile itself isn't from our standard range.
