Tigris K1 Press Fit

Tigris K1 is a multilayer pipe system designed for potable water and heating applications. It is ideally suited for installation on commercial projects such as educational establishments, apartment blocks and hotels. The system comprises multilayer composite pipe and high quality polyphenyl sulphone (PPSU) fittings with a fixed stainless steel sleeve, in sizes 16mm, 20mm, 25mm, 32mm, 40mm, 50mm, 63mm, and 75mm. An extensive range of fittings, accessories and tools complements the system.


The aluminum layer in the pipes reduces thermal expansion, making them comparable to copper. The cross-linked PEXc inner layer makes the pipes flexible. This means fewer connectors, simplifying installation and reducing cost.

Long-term performance

All Tigris K1 components deliver long-term performance under the most demanding conditions and temperatures. They are certified by major European agencies including WRAS, KIWA and DVGW.

Simple, secure and versatile

Simple connectors and a range of dimensions from 16-63 mm make installation fast and efficient. Use Tigris K1 in all types of developments, including the most demanding environments such as hotels and hospitals.

Reliable connections

Tigris K1 connectors are made from high performance PPSU to resist corrosion and encrustation. Their patented sculptured nose gives a secure connection with minimal push-in force. If an installer forgets to press, connectors are designed to show immediate visible leakage during pressure testing.
