alpex L multilayer composite pipe

The high-quality multilayer composite pipe consists of a cross-linked polyethylene inner surface, a butt-welded aluminium core, and a heat-stabilised polyethylene outer pipe. The three layers are joined with a special adhesion agent to form a single durable product.

alpex L fittings

The alpex L fittings are made of high-performance PPSU or dezincification-resistant brass and are equipped with pre-assembled stainless steel sleeves. The four dimensions between 40 and 75 mm can be pressed quickly and easily using the alpex press jaw with F-contour.


alpex-plus® fittings

The base body of the alpex-plus fittings is made of high-performance PPSU (polyphenylsulfone), a material which has been tested in space and offers extremely good impact strength while being entirely non-toxic. Threaded adaptors and screw fittings with base bodies made of dezincification-resistant brass complete the product range. FRÄNKISCHE uses stainless steel for the sleeve and the fastening element, which makes the alpex-plus fittings particularly suited for heavy-duty applications. Reduced installation time through innovative push-fit technology, slim design and, in addition, full compatibility with the proven alpex F50 PROFI system for drinking water and heating installations.
