System Information

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.


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.

Versatile, long term performance

All Tigris K1 components deliver long-term performance and are certified by major European agencies including KIWA and DVGW. Simple connectors and a range of dimensions from 16-75mm make installation fast and efficient. Tigris K1 can be used in multiple development types from hotels to hospitals.
