3fit®-Push (series 23000) | Plastic

Practical system push fittings with safe and innovative lock function from copper alloys for use in a system with SANHA MultiFit®-Flex and MultiFit®-PEX multi layer plastic tubes for hygienic drinking water and reliable heating installations. 

Due to their sophisticated construction, SANHA® system push fittings offer an especially safe and durable connection and are just as tight as press fittings. The push connection is easy to make and has the distinct advantage that no tools are required. In this way, using 3fit®-Push fittings incurs no cost for buying, repairing or maintenance of press machines.

3fit®-Push system fittings are ideally suited in narrow spaces where it might be difficult to press fittings with jaws or slings such as during the renovation of buildings.
