A double radius curve branch taking two connections into a 100mm Traditional Express stack at one level.

The Traditional Express double radius curve branch takes two connections into a 100mm push-fit cast iron soil stack at the same level, through swept 87.5° curves on opposite sides.

It is used where two WCs, or back-to-back bathrooms, share a stack at one floor. One fitting replaces two branches, saving height and joints on the elevation. For a single connection, use the single radius curve branch.

Size: 100mm (4″), 87.5°.

Cast iron to BS 416, with rubber joint seals to BS EN 681-1. Supplied in a factory black finish that can be overpainted, including in our linseed oil finish.

All FAQ
What is the TX Double Radius Curve Branch used for?
It joins two secondary branch lines into the main Traditional Express soil stack, each connection made with a smooth 87.5 degree radiused curve rather than a sharp junction.
Why choose a radius curve branch over a standard branch?
The curved profile reduces flow resistance and turbulence at the junction compared with a sharp-angled branch, which can benefit drainage performance.
What size is the TX Double Radius Curve Branch?
It is 100mm diameter with two 87.5 degree radiused branch connections.
Is this fitting suitable for listed building installations?
Yes, it is part of the Traditional Express cast iron push-fit soil pipe system, the authentic choice for listed and period buildings.
How do I get a price for the TX Double Radius Curve Branch?
Prices for each size and option are shown on this page, ex VAT. For a full schedule or a project quotation, please call 0333 987 4452 or use the contact form.
