Main highlights

The only approved waste water inner reducers for vertical and horizontal installation that do not require a sleeve. Tested and approved by DIBt Z-42.1-366.
The nominal widths DN can be called differently at different suppliers or DIY stores, but it is still always the same dimensions or the same outer diameter or the same pipe or moulding: DN75 = DN70 (old designation) actual outer diameter pipe each 75 mm | DN110 = DN100 (old designation) actual outer diameter pipe each 110 mm. DN160 = DN150 (old designation) actual outer diameter pipe each 160 mm.
Low effort with the waste water inner reducer offered here: cut pipe with angle grinder flush to the ground. Insert waste water inner reducer to stop of reducer. It should seal well, possibly Chamfer inside and use lubricant.
Fits HT pipes (DIN-EN 1451-1), KG pipes (DIN-EN 1401-1). hot water (90°C). Tested fire behaviour according to DIN 4101 B2. Colour: dust grey RAL 7037. The seals comply with DIN EN 681, EPDM. Indoor use
Connection side 1: connection for the pipe into which the reducer is inserted with seal. Connection side 2: A stop and a reduced sleeve inside for the tip end of the pipe which is reduced. The flow direction is always from the tip end of one part to the sleeve of the other part and always from small diameter to large diameter. So it is always reduced against the flow direction.

Thanks to the great success on the market, the manufacturer has now phased out the standard HT and is now replaced by the naturally backward compatible HT Safe system.
HTSafe meets fire protection class B1 and is therefore considered flame retardant.
HTSafe meets all sound insulation levels from I to III and is therefore applicable in single-family homes, residential and commercial properties and hospitals.
HTSafe is the successor product of HT. Thanks to many improvements, it can be used in all areas of building construction.
Approval is not required, as HTSafe is manufactured according to European standard DIN EN 1451-1.
