Gibault Joint (Unión Gibault) to NCh404
Overview:
This NCh404‑compliant Gibault joint is a dedicated ductile‑iron flexible coupling developed for Chile municipal water network projects.
It is specially designed for connecting Class AW‑20 asbestos‑cement pipes, and also works for compatible plain‑end ductile‑iron pipes.
Featuring three‑lugs bolt‑tightened construction, this fitting provides angular deflection and axial movement compensation for buried pipelines, effectively absorbing ground settlement and minor pipe displacement for underground potable‑water distribution systems.
Black bituminous coating offers reliable anti‑corrosion performance for buried service.
