Tuscan Mechanical BS416 Soil Boss Pipe Double at 90°

£137.10 ex VAT (£164.52 inc VAT)

Coupling-jointed cast iron soil and waste system, compatible with BS 416 pipework. Boss Pipe Double at 90°. Cast iron, supplied factory coated.

Product code: MS4055.

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

The Tuscan Mechanical BS416 Soil range is a coupling-jointed cast iron soil and waste system, dimensionally compatible with BS 416 pipework. Plain-ended pipes and fittings are joined with bolted ductile iron couplings, so there are no caulked or sealed sockets. A stack goes together quickly, and individual fittings can be taken out later without disturbing the rest of the run. Conversion couplings join it to existing socketed LCC pipe, which makes it a practical choice for repairs and extensions to older stacks as well as new work.

Product code MS4055. Nominal weight 2.2 kg.

Typical use: Two small-bore waste connections into a stack at one level.
