Rectangular Pipe to Round Connector

Price range: £265.40 through £444.00 ex VAT (£318.48 – £532.80 inc VAT)

Cast iron connector from 100x75mm to 150x100mm rectangular downpipe to 65mm, 75mm or 100mm round, in primer or black painted finish.

UK delivery from £45. Longer items are despatched palletised. See delivery rates.

The Rectangular Pipe to Round Connector changes a rectangular downpipe to a round section, for connection to a round pipe, a round gully inlet or an underground drain socket.

It is used at the foot of a run where the below-ground drainage takes a round pipe, or where a rectangular run must join an existing round system.

Round outlets are 65mm, 75mm or 100mm. The 100mm round outlet is not made for 125mm x 70mm pipe.

All fittings in our rectangular range are cast iron to BS 460:2002, made to the same moulded profile so pipes and fittings line up neatly on the elevation. Every fitting is supplied either in primer, ready for painting on site, or in factory black. For listed buildings and conservation areas we also offer hand-applied linseed oil paint in heritage colours, which stays breathable and flexible and is straightforward to maintain. Stocked items are usually dispatched within 5 to 7 working days; allow around 6 to 7 weeks where a linseed oil finish is specified.

Rectangular pipe sizes: 100mm x 75mm (4″ x 3″), 125mm x 70mm, 125mm x 100mm (5″ x 4″) and 150mm x 100mm (6″ x 4″).

Suitable for listed buildings, conservation areas and heritage restoration. For specification support or a project quotation, call 0333 987 4452.
