PPR-CU Antibacterial Copper-Lined Pipe — Manufacturer & Private-Label Supply
PP-R plus an inner copper layer for hygienic potable hot & cold water. Hitze PPR-CU fuses the corrosion-free, leak-free performance of German-standard PP-R with the oligodynamic (antibacterial) action of an integrated copper bore.
Engineered in Germany to DIN 8077/78 and EN ISO 15874, SKZ-tested. Available OD 20–63 mm for wholesale and private-label programs across 118+ export markets.
Trade & OEM only — for distributors, importers and private-label brands sourcing certified antibacterial pipe by the container, not a retail listing.

The Product
See the Copper-Lined Antibacterial Pipe
A PP-R body you already know how to weld, with a copper bore you can market as a hygiene upgrade. (Cut-section and copper-bore photography is being finalized; captioned frames show exactly what ships.)
What It Is
What Is PPR-CU Pipe? PP-R With an Antibacterial Copper Bore
Standard PP-R is already the workhorse of modern potable plumbing: corrosion-proof, scale-resistant, and heat-fusion welded into fully homogeneous, leak-free systems. PPR-CU takes that base and bonds a thin metallic copper layer to the inner wall of the pipe.
Standard PP-R (Random Copolymer Polypropylene) carries water reliably and joints homogeneously — but a plain plastic bore does nothing to control what grows inside it. PPR-CU bonds a thin metallic copper layer to the inner wall, and that copper surface delivers two things a plastic bore cannot:
- Antibacterial action (oligodynamic effect): trace copper ions released at the wetted surface disrupt bacterial cell membranes, suppressing biofilm and microbial colonization inside the pipe — a passive, chemical-free hygiene mechanism that works continuously over the pipe’s service life.
- Smooth, low-scale bore: the copper-lined inner wall stays clean and slick, minimizing scale build-up and preserving flow rate and water clarity in long-run potable systems.
The result is a pipe that carries water like PP-R but keeps the water pathway hygienic like copper — without copper’s corrosion, cost, and jointing complexity. Hitze produces PPR-CU across the full PP-R family range, OD 20 mm to OD 63 mm, to DIN 8077/78 and EN ISO 15874.

Where It Wins
Built for Potable, Hospital & Hotel Water Systems
PPR-CU is not a general-purpose upgrade — it earns its premium exactly where microbial control matters most.
Hospitals & Healthcare
Water systems where biofilm and waterborne pathogen risk (e.g. a Legionella management strategy) demand every hygienic advantage. The antibacterial copper bore is a passive line of defense inside the pipe itself.
Hotels & Hospitality
Long, intermittently-used risers and branch lines where stagnant water and scale are chronic problems. The smooth, low-scale bore protects guest-water quality and flow.
Residential Potable Hot & Cold
Homeowners and developers specifying a premium, hygiene-first potable system for kitchens and bathrooms, without switching material families.
Commercial & Institutional
Schools, care homes, and food-grade facilities where potable-safe, cleanable pipework is a spec requirement.
For any of these, PPR-CU installs on the same heat-fusion workflow and the same Hitze PP-R fittings your crews already use — so the hygiene upgrade adds no new tooling and no new failure modes at the joint.
Size & Fusion
Size Range: OD 20–63 mm, Fully Fusion-Weldable
Hitze PPR-CU covers branch runs through main risers in one homogeneous, weldable system — from fixture branches to high-flow feeds.
| OD (mm) | Typical Use |
|---|---|
| 20 | Fixture branches, short runs |
| 25 | Room / floor branch lines |
| 32 | Sub-mains, apartment risers |
| 40 | Distribution mains |
| 50 | Building risers |
| 63 | Main risers / high-flow feeds |
- Base material: PP-R random copolymer with integrated inner copper layer.
- Service: hygienic potable hot & cold water.
- Jointing: socket heat-fusion welding, identical to standard PP-R, using Hitze PP-R fittings — no transition fittings, no galvanic joints, no new tooling.
- Full dimension / SDR / pressure-class table: available on request in the technical data sheet (exact SDR & model list — coming soon).
The Copper Bore
How the Copper Layer Keeps the Water Pathway Hygienic
The hygiene benefit is not a coating claim — it is a metallic copper surface working passively against biofilm every hour the pipe is in service.
Copper has long been recognised for its oligodynamic effect: at the wetted surface, trace copper ions disrupt bacterial cell membranes, suppressing the biofilm that would otherwise colonise a plain plastic bore. Because the mechanism is the copper itself — not a chemical dose or an additive that leaches out — it keeps working continuously across the pipe’s whole service life.
- Passive & chemical-free: nothing to top up, nothing to wear out — the copper bore is the hygiene system.
- Low-scale, high-flow: the smooth copper-lined wall resists scale, protecting flow rate and water clarity on long risers and intermittently-used branches.
- Potable hot & cold: engineered for drinking-water service, built to DIN 8077/78 and EN ISO 15874 and SKZ-tested.

Hitze is the house brand of GERMANY Hitze INDUSTRY CO., LTD — founded 1974, over 50 years of pipe engineering — a 120,000 m² production base with 1,000+ employees, exporting to 118+ countries. German trademark registered at the Deutsches Patent- und Markenamt, Munich (Reg. No. 30 2020 005 484).
Every PPR-CU pipe is built and verified against:
- DIN 8077 / DIN 8078 — German dimensional and quality standards for PP-R pipe.
- EN ISO 15874 — European standard for plastics piping systems for hot and cold water installations.
- SKZ-tested — verification by the SKZ, Germany’s plastics testing and certification institute.
For potable and regional market access, Hitze holds and asserts the relevant certificate families — NSF/ANSI 61 (potable contact), WRAS, DVGW, cUPC/UPC, CE + DoP — across the applicable range. Certificate numbers are supplied in the Hitze Cert Pack on request (we assert the families; we never publish numbers we can’t evidence).
