## Long description

KAN-therm welding fittings 40 mm 04212340 are metal butt fusion fittings designed to connect 40 mm polyethylene (PE) pipes in plumbing and heating systems. Engineered for professional installation, these fittings create a continuous, mechanically robust joint intended for water supply, central heating and underfloor heating circuits. The design supports standard fusion welding processes to produce leak-resistant connections compatible with system pressures typical for building services.
Advantages
The fittings provide a secure, long-lasting connection through butt fusion welding, minimising the risk of leaks and mechanical failure. Made from metal suitable for reliable thermal and structural performance during fusion, the component offers consistent geometry to ensure proper alignment and ease of assembly with appropriate fusion equipment. Their construction is intended to withstand the thermal cycles and pressures common in plumbing and heating applications.
Suitable for
 Joining 40 mm PE pipes in potable water distribution systems
 Connections within central heating installations
 Underfloor heating manifolds and branch connections
 Professional plumbing and HVAC fusion welding applications
Key specifications
 Material: metal fitting designed for butt fusion with polyethylene pipes
 Nominal pipe diameter: 40 mm
 Connection method: butt fusion (fusion welding) compatible
 Intended use: water supply, central heating, underfloor heating systems
 Installation level: professional installation recommended
How to use
Prepare the PE pipe ends by cutting square and cleaning them according to fusion equipment manufacturer instructions. Align the pipe ends and the fitting in the fusion tool or heater plate designed for butt fusion of 40 mm components.
