BONFIX Alupers: Multilayer Pipe & Press Fittings | Saniso

BONFIX Alupers: which multilayer pipe and press fittings do you need?

For drinking-water and central-heating pipework, BONFIX Alupers multilayer pipe with matching Alu-press brass press fittings gives you a complete press system on one brand.

At Saniso the BONFIX Alupers range covers 141 products: 23 multilayer pipes (13 bare + 10 ISO 6 mm insulated) and 118 Alu-press brass press fittings. Pipe diameters run 16×2, 20×2, 25×2.5, 26×3 and 32×3 mm; fittings continue through 40 mm. Browse Multilayer pipe, Press coupling and the size leaves Press coupling 16 mm, Press coupling 20 mm, Press coupling 25 mm, Press coupling 26 mm, Press coupling 32 mm and Press coupling 40 mm. They sit under Piping systems and Installation material. Saniso B.V. in Zwaag sells the BONFIX brand as a wholesaler and webshop.

What is BONFIX Alupers (multilayer pipe + Alu-press)?

Alupers is BONFIX multilayer pipe: a 5-layer tube with PE-RT II inner and outer layers and an aluminum interlayer (as stated on Saniso product specifications). Alu-press is the matching brass press-fitting line for that pipe. Together they form the in-scope assortment of 141 SKUs on saniso.nl — not the separate BONFIX brass compression (knel) fittings that also appear on the BONFIX brand page.

Example ISO pipe (example product): 48720375 — Alupers ISO 6 mm blue 32×3 mm. Example bare pipe: 48720104 — Alupers 16×2 mm (10 m). Example fitting: 48730410 — Alu-press T-piece 16×16×16.

Why use Alupers multilayer pipe for plumbing and heating?

Product pages list drinking water and CV (central heating) as the application for Alupers pipe. The same system text on pipe and fitting pages describes a complete piping system for drinking water and central heating.

Where the product page states them, Alupers claims include a lightweight, easy-to-bend tube, a smooth wear-resistant surface, low noise, corrosion resistance, and 100% oxygen-tight / diffusion-tight construction, with a continuous medium temperature up to about +70 °C. Fitting pages add brass bodies, a 304 stainless steel press sleeve, double EPDM O-rings, size colour coding, and Leak Before Pressed. Product-page claims also mention KOMO certification up to and including 32 mm, European UBA drinking-water requirements, an expected lifespan of about 50 years, a system warranty according to the manufacturer's terms, and press jaws TH, H, U, F and CH. Cooling and low-pressure compressed air appear only in that product-page text block (“Why BONFIX Alu press”), not as a fixed application field on the specifications.

Who typically buys these products at Saniso?

Product pages say the system is developed for installers. Saniso B.V. in Zwaag sells BONFIX as a wholesaler and webshop, so typical buyers are professional installers and trade customers ordering Alupers pipe and Alu-press fittings for residential, renovation and non-residential drinking-water and heating jobs.

Pipe vs fittings: how Alupers and Alu-press map together

Use Alupers for the pipe run and Alu-press for every press joint, branch, reduction, thread transition, wall outlet or end cap. Product information states that Alu-press fittings fit BONFIX Alu press pipes.

Alupers pipe — bare vs ISO 6 mm insulated

Bare example: 48720110 (16×2 mm, 100 m). ISO example: 48720270 (ISO 6 mm red 16×2 mm, 50 m).

Alu-press fittings — types by job (T-piece, socket, screw bushing, …)

Browse by size under Press coupling 16 mm through Press coupling 40 mm.

Choosing diameter and roll length (16–40 mm · 10–100 m)

Match the outside diameter × wall of the pipe to the press fitting size. On Saniso, Alupers pipe is sold as:

• 16 × 2 mm — bare rolls 10 / 25 / 50 / 100 m; ISO 6 mm rolls 50 m (red and blue)
• 20 × 2 mm — bare 10 / 25 / 50 / 100 m; ISO 50 m
• 25 × 2.5 mm — bare 10 / 50 m; ISO 50 m
• 26 × 3 mm — bare 10 / 50 m; ISO 50 m
• 32 × 3 mm — bare 25 m (48720170); ISO 6 mm red 48720315 and blue 48720375 — check the live product page for roll length

Alu-press fittings extend to 40 mm (for example T-pieces and sockets) even though Alupers pipe on Saniso tops out at 32 mm. Short trials often start with a 10 m bare roll; typical installs use 25 m or 50 m; long runs in 16 and 20 mm have 100 m bare coils.

ISO colour: red vs blue insulated pipe

On Saniso titles, ISO colour is the insulation colour, not the white multilayer core:

• Red ISO 6 mm — five diameters, e.g. 48720270 (16×2 mm, 50 m)
• Blue ISO 6 mm — five diameters, e.g. 48720375 (32×3 mm)
• Bare Alupers — white tube, no ISO colour in the title

Pick red or blue to mark circuits (for example flow/return or hot/cold) according to your site conventions; both are the same Alupers multilayer construction with ISO 6 mm insulation in the product title.

FAQ

How do you choose the right multilayer pipe diameter?

Start from the pipe size already on site or from the design drawing, then order matching Alupers pipe and Alu-press fittings in the same millimetre. Saniso pipe sizes are 16×2, 20×2, 25×2.5, 26×3 and 32×3 mm; fittings also cover 40 mm. Open the matching size leaf (for example Press coupling 16 mm) and pick T-pieces, sockets or screw bushings in that size.

When do you need ISO 6 mm insulated pipe instead of bare Alupers?

Choose ISO 6 mm when the product title’s insulated jacket (red or blue) is what you need for the run — for example distribution lines where insulation is specified. Choose bare white Alupers when you want the multilayer tube without ISO in the title, often in shorter 10 m or long 100 m coils. Compare 48720270 (ISO red 16×2 mm) with 48720104 (bare 16×2 mm, 10 m).

Which Alu-press fitting types go with Alupers pipe?

All 118 Alu-press brass press fittings in this guide: T-pieces, sockets (equal and tapered), screw bushings, end pieces, wall plates, end caps, elbows, gemini brackets, and adapters to compression, M-press or insert. Product pages state they fit BONFIX Alu press pipes. Example starter set references: 48730410 (T-piece), 48730110 (socket), 48730310 (screw bushing).

What roll lengths are available for Alupers multilayer pipe?

From product titles: bare 16×2 and 20×2 in 10 / 25 / 50 / 100 m; bare 25×2.5 and 26×3 in 10 / 50 m; bare 32×3 in 25 m. ISO 6 mm 16–26 mm rolls are 50 m (red and blue). For ISO 32×3 mm red (48720315) and blue (48720375), open the product page rather than relying on a single length figure here.

What is the difference between Alu-press fittings and brass compression fittings?

Alu-press fittings are press couplings for Alupers multilayer pipe — the 118 items in this assortment. BONFIX also sells separate brass compression (knel) fittings on the brand page; those 20 articles are outside this guide and are not part of the Alupers / Alu-press press system assortment covered here. Adapter sockets “to compression” inside Alu-press remain in scope as press→knel transitions.
