PP-R Thermofusion Pipe and Fittings — Hot and Cold Water
Random polypropylene (PP-R) in a green line and a blue line, for hot and cold water inside buildings. It holds higher pressure than conventional plastic systems and is the system best suited to this job: more safety, longer service life, better quality of service. Pipe manufactured to ISO 15874-2, fittings to IRAM 13472.
The joint is made by thermofusion: pipe and fitting are heat-fused into a single piece of material, with no glue and no gasket. Threaded fittings carry a grooved male-thread metal insert, which grips teflon better and avoids isolation where the line couples to pipe of another material. Full catalog from 20 to 160 mm. Factory Direct by the container.

PP-R Line Specifications
PP-R PN 20 Pipe — Standard Line
The line’s everyday running sizes, all in 6 meter lengths.
| Diameter (mm) | Pressure class | Length (mm) |
|---|---|---|
| 20 | PN 20 | 6000 |
| 25 | PN 20 | 6000 |
| 32 | PN 20 | 6000 |
| 40 | PN 20 | 6000 |
| 63 | PN 20 | 6000 |
PN is the pipe’s nominal pressure class, in bar. The larger diameters — 50, 75, 90 and 110 mm — are listed in the next table.
Full Range and Pressure Classes
The three small sizes are also produced in PN 25. From 40 mm up, production is made to order, so those sizes get locked in when the container is built.
| Diameter (mm) | Pressure class | Length (mm) | Availability |
|---|---|---|---|
| 20 | PN 20 · PN 25 | 6000 | Running line |
| 25 | PN 20 · PN 25 | 6000 | Running line |
| 32 | PN 20 · PN 25 | 6000 | Running line |
| 40 | PN 20 | 6000 | Made to order |
| 50 | PN 20 | 6000 | Made to order |
| 63 | PN 20 | 6000 | Made to order |
| 75 | PN 20 | 6000 | Made to order |
| 90 | PN 20 | 6000 | Made to order |
| 110 | PN 20 | 6000 | Made to order |
Made to order means the size enters a factory run with the container, not that it does not exist. Send the diameter mix and we schedule it.
PP-R Fittings Catalog
All fittings are PN 20. Plain-end parts are joined by thermofusion; threaded parts carry a metal insert for coupling to pipe of other materials, valves, meters, and fixtures.

The metal insert
Threaded parts carry a grooved male-thread metal insert. The grooves grip teflon better, and the metal avoids isolation at the point where the PP-R line couples to pipe of another material. That coupling is where a mixed installation leaks first, and it is the reason the insert is there.
Where the PP-R Line Operates
Every application is the same one: pressurized hot and cold water inside a building, with joints nobody can inspect afterward.
Housing
Internal hot and cold water networks in residential construction — 20 and 25 mm on branches, 32 mm on the feed.
High-rise
Risers and floor-by-floor distribution, where PN 20 and a fused joint cover the pressure column.
Hospitality
Bathrooms and laundry on constant hot water, where a cemented or gasketed joint is the first thing to fail.
Domestic hot water
Runs from the heater or tank out to the fixtures, in green or blue depending on the site convention.
Retrofits
Replacing old internal networks, with threaded adapters from 1/2" to 4" to meet what is already in the wall.
Distribution
Counter assortment: 20, 25 and 32 mm with elbows, tees, stop valves and adapters — the core of the turnover.
Blue Line — Fittings Catalog
The blue line runs alongside the green: same PP-R material and same pressure class, in 20, 25, and 32 mm tubes at PN 20 and PN 25, and 40 to 110 mm at PN 20 on order. The color is a site convention that varies by market — tell us which you run and we build it that way.
Buying PP-R Wholesale — FAQ
What is thermofusion and why does it matter?
Pipe and fitting are heated and fused into each other: the joint becomes a single piece of material, not two pieces stuck together. There is no glue to degrade and no gasket to harden and seep. That is the main reason PP-R is the system specified for hot water in buildings — on a network that ends up inside a wall, the joint is the part nobody can inspect later.
What is the difference between PP-R and threaded PP?
The joint, and with it the job. PP-R is heat-fused and the installation is permanent: it belongs in in-wall distribution of hot and cold water. Threaded PP goes together and comes apart with a wrench, with no fusion tool and no cement, which is why it belongs on service connections and repairs where the line has to open again. Two different products from the same polypropylene family, not two versions of one.
What is the metal insert in the threaded fittings for?
For the point where the PP-R line couples to pipe of another material, to a valve, or to a fixture. The insert is a grooved male thread: the grooves grip teflon better and the metal avoids isolation at that coupling. Without it, the transition between materials is the first place a mixed installation leaks.
What is the difference between the green line and the blue line?
The color of the pipe. The material is the same random polypropylene to ISO 15874-2 and the pressure class is the same. In practice the color is how a crew keeps runs apart on site, and the convention changes from one market to the next. Tell us what your market runs and we set the green-to-blue split in the container.
Does this line suit a US plumbing wholesaler?
Usually not. This is metric goods to ISO 15874-2, sized in millimeters, and a US counter buys in inches to ASTM with NSF certification for potable water. Where this line does fit is Latin America and the Caribbean, where metric PP-R is the jobsite standard. For the US market the right conversation is PVC SCH 40 and the pressure line.
What is the minimum order?
Coverage is by the container, not the single stick. At 20, 25 and 32 mm the line is a running item; from 40 mm up, production is made to order in the run that ships with your container. If the pipe and fittings mix does not fill a container of its own, it combines with the rest of the water and drainage line. Send the SKU mix and destination and we put the configuration together.
