Union with flat sealing made of low-carbon steel, electro-galvanized with a zinc layer of 8–15 µm and additional chromate passivation – ensuring corrosion resistance in heating and cooling installations. The O-ring seal made of EPDM rubber (EDPM) complies with PN-EN 681-1, ensuring tightness even under cyclic temperature and pressure changes.

The connection on one side is a crimp sleeve for a pipe with an outer diameter of 28 mm (DN 25), and on the other side – a union nut with a 1 1/4 inch thread (DN 32). The overall length is 41 mm, with the crimping section having a working length of 8 mm and the threaded section 2 mm.
