GW Steel Sprinkler coupling - 28 Rp3/4" 1511044005

Galvanized steel fitting for fire suppression systems, designed for press-fitting installation. One side features a press-fit coupling compatible with press-fitted pipes, while the other side is equipped with an external BSPT-R thread (ISO 7-1 / EN 10226-1), enabling connection to valves, nozzles, or other components with tapered threads.

Manufactured from Fe/Zn88 steel with a zinc coating thickness of 8–15 µm, ensuring corrosion resistance in humid conditions typical of sprinkler installations. The internal O-ring seal guarantees leak-tightness without the need for additional sealing tape or paste.

The controlled leak function (LBP) acts as an additional safety layer: in case of damage or improper press-fitting, water does not escape violently but slowly through a
