Singapore – Wavin, a world-leading solutions provider for the building and infrastructure industry, has expanded its line-up of innovative pipe and fittings solutions with the launch of the Wavin Tigris K5/M5. The Wavin Tigris K5/M5 is a brand-new press fitting series with a unique acoustic leak alert feature that sets new standards of water management for metal-plastic pipe connections. The Wavin Tigris K5/M5 offers a new approach for governments and organisations looking to secure their water supply right where it all begins – from installation in the buildings.

Not just any ordinary fitting

The Wavin Tigris K5/M5 are the world’s first fittings with an ACOUSTIC LEAK ALERT. In a leakage test executed with air instead of water, an unpressed fitting will generate a loud and clear whistle sound (+/- 80 dBA), alerting installers of leaks when fittings are not fully pressed.

According to Ruurd van Leeuwen, Global Product Manager (Hot & Cold) for Wavin, “When testing with air instead of water, leak and pressure tests will no longer be a challenge in the building installation phase. Testing with air has several advantages such as no risk of bacterial growth (Legionella) due to water stagnation in the period between testing and final use of the installation. Additionally, it avoids slippery work spaces or water damage and there is no need for using leak sprays. The method is quick, clean and safe as it already works at 0.15 bar, making it also a perfect solution to check prefabricated installations. Ultimately, this approach eliminates dependency on early water supplies at the building site, as a simple air compressor will do the job.

A new generation

As successor of the highly rated Wavin Tigris K1/M1 fitting, the new Tigris K5/M5 have kicked it up a few notches. The Wavin Tigris K5/M5 are best in class in flow performance, with improved flow area, thanks to the increased inner bores, called OPTIFLOW. It also features MULTIJAW, which means that the fittings can now also be pressed with the most common pressing profiles such as U and Up, TH, H and B. This enables installers to easily switch to Wavin, without switching tools and retain their system warranty. Furthermore, to make the installation as easy and reliable as possible for installers, the fitting also incorporates IN4SURE, 360° pipe visibility to check if the pipe is inserted properly. It also includes EASYFIT, which means it is not necessary to calibrate or chamfer the pipe after cutting. The Wavin Tigris has two core lines based on the preferred choice of body material. The Wavin Tigris K5 is a press fitting with bodies made of the high technical performance plastic Polyphenylsulfone (PPSU), while the Wavin Tigris M5 is a metal press fitting with bodies made of UBA listed drinking water approved brass materials. Both radial press-fits, in PPSU or Brass, cover a complete range of fittings that fit up to 40 mm multi-layer composite pipes with Tigris K5/M5 and 50 – 75mm with Tigris K1/M1.

The new Wavin Tigris K5/M5 was launched in Southeast Asia on 8 October 2021.
