Key specifications
 Brand: Supratherm
 Model / MPN: 2203978
 EAN: 5945792203978
 Material: PP‑R (polypropylene random)
 Connection size: 25 mm
 Maximum service temperature: up to 90°C

How to use
Prepare pipe ends by cutting them square and removing burrs. Fit the coupling onto the cleaned pipe ends using the appropriate polypropylene welding or fusion method recommended for PP‑R systems (socket fusion, butt fusion or electrofusion as applicable). Ensure correct alignment and follow the heating, assembly and cooling times specified by the welding equipment manufacturer to obtain a reliable, leak‑tight joint.
Usage recommendations
Use only approved PP‑R welding equipment and follow local plumbing codes. Verify compatibility of pipe and fitting dimensions before welding. For systems operating near the maximum temperature, consider thermal expansion and provide adequate supports and alignment to prevent stress on joints.
