PE-brass adapter with external thread GZ, d25x3/4" PE100, SDR11, PN10 gas/PN16 water, for assembly with electrofusion welding or electroreduction fitting. 720920707

PE-brass adapter – reliable connection of piping systems

This PE-brass adapter with an external GZ thread, with a diameter of 25x3/4 inch, is a key element in water and gas installations. Designed to connect polyethylene PE100 pipes with brass threaded connection elements, it ensures durability and safety. The Georg Fischer product, with catalog number 720920707, is ideal for both professional installers and end users.

Design and application

The adapter is designed for installation using electrofusion or electroreduction welding technology. Made of polyethylene (PE) and brass, it guarantees resistance to corrosion and mechanical damage. Its construction allows for the connection of a plastic sleeve (for welding/fusion) with a cylindrical gas external thread (BSPP). This makes it possible to effectively connect different types of installations. The nominal connection diameter is DN 25, and the outer diameter of the PE pipe is 25 mm. The connection length is 179 mm, and the working length is 311 mm.

Operating parameters and compliance with standards

The adapter is characterized by a standardized dimension ratio SDR 11 and withstands a pressure of PN10 for gas and PN16 for water. It can be used in systems with a medium temperature of 5°C to 40°C. The PE100 material provides high resistance to cracking under stress, which translates into long-term connection reliability. The connector is compatible with water and gas installations where a solid and tight connection of PE elements with brass components is required. The circumferential stiffness class specified as “Other” indicates specific product properties adapted to different working conditions.
