Traditional Express Soil Pipe System Single Radius Curve Branch 87.5 100mm
CODE TX4030 Category

Single Radius Curve Branch 87.5 100mm

£108.40 ex VAT (£130.08 inc VAT)

An 87.5° radius curve branch for WC connections into a 100mm Traditional Express cast iron stack.

UK delivery from £30. Fittings are despatched boxed. See delivery rates.

The Traditional Express single radius curve branch joins a connection into a 100mm push-fit cast iron soil stack through a swept 87.5° curve, which directs flow downwards and reduces the risk of blockage.

It is the preferred junction for a WC connection. Where rodding access is needed at the junction, use the radius curve branch with door; for two connections at one level, the double 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.

Suitable for listed buildings and conservation area work. For specification advice, a full schedule or a quotation, call 0333 987 4452 or use the contact form.

All FAQ
What is the TX Single Radius Curve Branch used for?
It joins a secondary branch line into the main Traditional Express soil stack 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 Single Radius Curve Branch?
It is 100mm diameter with an 87.5 degree radiused branch connection.
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 Single 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.
