For a rigid PVC pipe measuring 125 mm in outer diameter, the COYOUCO hard plastic pipe is the closest match in this product list. The Ventilazione 125 mm hose is a flexible option for ventilation, not a rigid plumbing pipe. The other three products are smaller U.S.-sized PVC items and are not substitutes for 125 mm pipe. Check the dimensions and intended use before choosing.

|---|---|---|
| COYOUCO PVC pipe | Short rigid-pipe projects | 125 mm outer diameter; 0.2 m length listed |
| Ventilazione ventilation hose | Air and vapor movement | 125 mm ventilation section |
| LR conduit bodies | Electrical conduit turns | 1-1/4-inch conduit size |

| Schedule 40 pipe, 1/2 inch | Small plumbing projects | 0.84-inch outer diameter |
COYOUCO 125 Mm Rigid PVC Pipe
This is the closest match for someone searching for a 125 mm rigid PVC pipe. The listed specifications give a 125 mm outer diameter and 3.1 mm wall thickness. The product is described as hard PVC for drainage, ventilation duct installation, home improvement, and DIY projects.
Best for: Buyers who need a short, rigid section with a stated 125 mm outside diameter. The listing shows a 0.2 m piece, while its features say other lengths from 0.2 m to 1.5 m are available.
Limitation: Confirm the selected length and connection dimensions before ordering. The feature text mentions compatibility with “50mm” fittings, which does not establish compatibility with a 125 mm connection.
Ventilazione 125 Mm Ventilation Hose
This product is a 125 mm ventilation hose rather than a rigid PVC pipe. Its stated purpose is to support air renewal and the quick evacuation of vapors and odors, making it more relevant to ducted ventilation than drainage or pressurized plumbing.
Best for: Buyers seeking a 125 mm ventilation component for moving air, vapors, or odors. It was selected because its listed diameter matches the search and its purpose is clearly ventilation.
Limitation: The supplied product details do not specify hose length, construction material, or pressure suitability. Do not treat it as a rigid pipe or assume it is suitable for water service.
LR PVC Conduit Bodies, 1-1/4 Inch
These rigid PVC conduit bodies are for electrical conduit runs, not general-purpose 125 mm drainage pipe. The LR design makes a 90-degree turn and provides access for pulling, splicing, or maintaining wiring. The listing describes two bodies with covers and gaskets, a flat back for close wall mounting, and installation using primer and solvent cement.
Best for: Buyers working with a 1-1/4-inch electrical conduit system who need an accessible corner fitting. It is included as a related PVC product, not as a 125 mm pipe match.
Limitation: Its stated size is 1-1/4 inch, so it is not a 125 mm pipe or fitting.
Schedule 40 PVC Pipe, 1-1/4 Inch
This short Schedule 40 pipe is listed for drainage, pool and spa installations, and cold-water applications. Its stated dimensions are 1.66 inches outer diameter and 1.38 inches inner diameter; the listing also gives a 370 PSI pressure rating.
Best for: Buyers seeking a small Schedule 40 plumbing pipe for one of the listed applications. It offers more useful application and pressure details than the conduit fitting, but it is not close to a 125 mm nominal pipe size.
Limitation: The listed length is 12 inches, and the product dimensions do not match 125 mm pipe.
Schedule 40 PVC Pipe, 1/2 Inch
This 12-inch Schedule 40 pipe is listed for residential plumbing, drainage, pool and spa installations, and cold-water applications. Its stated outer diameter is 0.84 inch, its inner diameter is 0.622 inch, and its listed pressure rating is 600 PSI.
Best for: Buyers who need a short, small-diameter Schedule 40 section for an application listed by the seller. It is included as a PVC alternative, not a size match for 125 mm.
Limitation: Its 1/2-inch nominal size is substantially smaller than 125 mm.
Buying Guide: How To Choose PVC Pipe 125 Mm
Do you need rigid pipe or flexible duct?
Choose based on the job. The COYOUCO product is described as rigid pipe for drainage and ventilation duct installation. The Ventilazione product is a hose intended to move air and evacuate vapors or odors. A flexible ventilation hose should not be substituted for rigid drainage pipe without confirming that the application and connections allow it.
Which measurement should you verify?
Check whether 125 mm refers to the outside diameter, inside diameter, or nominal size. The COYOUCO listing specifically gives a 125 mm outer diameter and 3.1 mm wall thickness. Fittings must match the relevant pipe dimension and system standard. Do not rely on a vague size label alone.
Is a U.S. Schedule 40 pipe an equivalent?
Not automatically. The listed Schedule 40 products are 1-1/4 inch and 1/2 inch nominal sizes, with their own stated dimensions. They are not presented as 125 mm pipe. Match pipe and fittings by their actual dimensions and intended standard rather than assuming metric and inch sizes are interchangeable.
What should you confirm before buying?
- Intended use: drainage, cold water, electrical conduit, or ventilation.
- Required pipe length and whether the selected product option supplies it.
- Inside and outside dimensions, wall thickness, and matching fitting size.
- Pressure suitability where the system carries water under pressure.
- Whether the product is rigid pipe, a hose, or a specialized fitting.
