The Uponor Wipex Male Coupling PN6 connects compatible Uponor Ecoflex PN6 crosslinked polyethylene (PE-Xa) carrier pipes to matching Wipex fittings or suitable threaded connections.
Designed to grip the pipe securely, the coupling maintains a reliable seal across changing operating temperatures. The range covers pipe dimensions from 25mm to 110mm, with different sizes available to suit your installation.
Select the coupling to match the carrier pipe’s outside diameter, wall thickness and required thread size. PN6 and PN10 couplings are designed for different pipe specifications and must be selected accordingly.
Follow Uponor’s installation instructions, including the specified sealing method when connecting to fittings outside the Wipex range.
For pre-insulated pipe installations, use the appropriate rubber end cap and insulation components to protect the exposed pipe end and completed connection.
