Buy DN/OD 160 — Guide & Tips
The DN/OD 160 category includes 84 items for sewer pipe systems with an outer diameter of 160 mm according to the metric nominal size standard DN/OD (Outside Diameter). These pipes are specifically designed for underground wastewater lines and sewerage and are connected via push-fit sockets. The material offers high mechanical load capacity, so the pipes remain permanently tight even under earth cover and traffic loads.
What should you look for when buying? The wall thickness is crucial: For public sewers and heavily loaded areas, pipes of class SN 4 or higher are recommended, while SN 2 is sufficient for private property drainage. Pay attention to the correct socket geometry – DN/OD 160 pipes are compatible with standard push-fit sockets that allow quick assembly without adhesive. For direction changes you need bends (usually 15°, 30°, 45° or 90°), for branches fittings such as branches or cleaning pipes.
Typical applications are house drainage, rainwater drainage and irrigation systems in garden and landscape construction. If you are expanding an existing sewer pipe system, check the existing nominal size: DN/OD 160 fits the common systems of KG pipes. For smaller diameters, take a look at the DN/OD 110 category , for larger cross-sections the DN/OD 200 variant.
A common mistake: using pipes with the wrong pressure rating. DN/OD 160 sewer pipes are designed for non-pressurized wastewater systems – do not use them in pressure lines. Also plan sufficient slope (at least 1–2%) to prevent blockages. With the right selection of fittings and seals, you can install a durable system that lasts for decades.
Popular DN/OD 160 products
These three product types cover the most common requirements in pipe installation: the 45-degree bend enables direction changes without flow separation, the cleaning pipe provides access for maintenance and inspection, and the branch connects main and secondary lines. Combine these fittings with straight DN/OD 160 pipes and matching seals to build a complete wastewater system. When selecting, pay attention to the angle specification – 45 degrees is suitable for gentle deflections, while 90-degree bends are intended for tight spaces.
Frequently asked questions about DN/OD 160
What wall thickness is recommended for DN/OD 160 pipes?
The wall thickness depends on the load class. For private property drainage, class SN 2 (2 kN/m²) is sufficient, while public sewers and areas with vehicle traffic require class SN 4 (4 kN/m²) or higher. Check the installation depth: from 1.5 m of soil cover, SN 4 is standard. The exact wall thickness varies by manufacturer – typical values for DN/OD 160 are 3.2 mm to 4.5 mm. When in doubt, choose the higher class, as the additional cost is low and safety increases.
Can I connect DN/OD 160 pipes with other nominal diameters?
Yes, using reducers or branches, connection to other diameters is possible. A typical example is the transition from DN/OD 160 to DN/OD 110 for house connections. Use special transition fittings with two different socket diameters for this. Ensure that the seals match the respective system – KG systems are compatible with each other, but not always with HT pipes (high temperature). For a tight connection, always use the appropriate push-fit socket with rubber lip seal.
How deep do I need to lay DN/OD 160 pipes?
The minimum installation depth depends on the frost line and the load. In Germany, the frost depth is about 0.8–1.0 m – lay pipes at least 1 m deep to avoid frost damage. Under traffic areas, 1.2–1.5 m is common. Plan a gradient of 1–2% (1–2 cm per meter) to ensure wastewater flows safely. For shallow depths, protect the pipe with a concrete slab or a sand bed. For exact requirements, consult the local drainage regulations.
Which seals do I need for DN/OD 160 push-fit sockets?
Standard rubber lip seals made of EPDM or NBR are used, which are integrated into the socket. These seals are suitable for wastewater up to 60 °C and resistant to common household chemicals. Ensure the seal is clean and undamaged – lightly grease it with silicone grease before assembly to make insertion easier. For repairs on existing pipes, you can purchase retrofit seals for smooth pipe ends. Do not use adhesives or sealants, as the system is based on a pure push-fit connection.
More categories in the drainage pipe system
The category DN/OD 160 is part of the overarching drainage pipe system, which offers various nominal diameters for different drainage volumes. If you need a smaller pipe for house connections or downpipes, DN/OD 110 is the right choice – it is the standard for washbasins, showers, and toilets. For larger wastewater volumes in multi-family buildings or commercial operations, DN/OD 200, which transports twice the volume of DN/OD 160.
The choice of nominal width depends on the number of connected drainage fixtures: a single-family home usually gets by with DN/OD 110 for the main drain, while DN/OD 160 is used for main collectors and rainwater downpipes. When planning a new build or renovation, you should calculate the maximum load – a plumbing professional can help with a simple calculation. All the mentioned categories use the same push-fit socket system, so you can combine fittings and gaskets.
In brief
DN/OD 160 sewer pipes with an outer diameter of 160 mm are the first choice for underground wastewater lines and sewerage systems. They are connected via push-fit sockets, are mechanically resilient, and are designed for gravity systems. When selecting, pay attention to the wall thickness (class SN 2 or SN 4), the correct slope, and suitable fittings such as bends, branches, and transition pieces. The category includes 84 items – from straight pipes to angles and adapters. For smaller or larger diameters, the sibling categories DN/OD 110 and DN/OD 200 are available.
