Full details
The Wavin Tigris K5 Reducing Coupler is an essential component for professional plumbers and DIY installers looking to optimize flow efficiency in their piping systems. Featuring advanced Opti Flow technology, this fitting significantly reduces pressure loss by utilizing an orifice up to 50% larger than standard market alternatives.

Setup, Compatibility & Care
To ensure a successful installation, verify that your pipe ends are cut squarely and deburred properly before insertion. The K5 series is compatible with matching press-fit pipe systems; ensure you are using the correct jaw profile for the Wavin Tigris system to achieve a secure seal. Do not force the fitting if the pipe encounters resistance. Once installed, perform a pressure test according to local plumbing codes. For long-term care, avoid using harsh chemical cleaners on the exterior of the fitting, and perform periodic visual inspections for signs of moisture or damage during routine maintenance checks.
