AIS PPSU
Preserves water quality
The PPSU prevents metal migration into the water, ensuring it remains pure and free from contaminants.

AIS PPSU
Ideal for installations in hard and aggressive water areas
PPSU does not corrode and prevents incrustations.

AIS PPSU
Resistant to chlorination
This system is highly recommended installations where disinfectant treatments are mandatory.

AIS PPSU
Reduced weight, increased efficiency
Made of PPSU with a density 6.5 times lower than brass, these fittings are easier to transport and install, reducing logistics costs and installation effort.

AIS PPSU press-fitting system for multilayer pipes
AIS PPSU system offers a complete range of press-fittings made of PPSU (a high-performance polymer), perfectly combined with AIS multilayer pipes, designed for drinking water, domestic plumbing, and heating installations. AIS PPSU fittings provide an excellent alternative to metallic fittings, delivering comparable performance while preserving water purity and maintaining a stable and competitive price. This makes them an attractive option for modern installations prioritizing both quality and cost-efficiency.
PPSU system benefits
)
BENEFIT
Preserves water quality
Manufactured in high-quality PPSU, these fittings prevent metal migration into the water, ensuring it remains pure and free from contaminants, without altering its color, taste or smell. This is particularly important in the current regulatory context, which emphasizes the protection and quality of drinking water.
BENEFIT
Ideal for installations in hard and aggressive water areas
PPSU does not corrode and prevents limescale and incrustations ensuring greater durability and maintaining an optimal flow rate over time, even in extreme conditions.
BENEFIT
Chlorine resistant
AIS PPSU fittings are highly recommended for installations where disinfectant treatments are mandatory. This system is optimal for plumbing and heating installations in buildings like hospitals, care homes, food industry facilities, etc.
BENEFIT
Reduced weight, increased efficiency
With a density 6.5 times lower than brass, these fittings are easier to transport and handle, reducing logistics costs for distributors and minimizing effort for installers. This results in a faster and more efficient installation process.
PPSU system advantages
Access to data sheetWide range and versatility
Available in diameters from 16mm to 63mm. AIS PPSU are multi-jaw fittings. From 16mm to 32mm compatible with U, TH, H and RFZ profiles and from 40mm to 63mm compatible with U and TH profiles.
Quick and reliable installation
Press-fitting system allowing a quick installation. Our fittings have an inspection window that allows to check the right introduction of the pipe.
Maximum efficiency without flow reduction
PPSU and multilayer pipes low roughness prevents the formation of limescale, ensuring plumbing and heating systems maintain an optimal flow rate over time.
Mechanical strength
Despite their reduced weight, AIS PPSU fittings offer high mechanical strength, ensuring durability and reliability in demanding installations.
