Coupling
As a simple fitting with wide applications, bushings are used to connect two pipes both on their male ends or the male end of a pipe to the male end of a fitting. Couplings are cylindrical fittings with two female ends and function as a connecting piece between two pipes of the same diameter. An important advantage of a coupling is that it allows for easy and fast connection of UPVC pipes without heating. Manufactured according to BSEN 1329‑1 and INSO 9119‑1, the well‑engineered couplings made by Khuzestan Hose and Pipe Co. can withstand external loads, cause minimum pressure loss, and come in various sizes for different general‑ and special‑purpose applications.
Specification of Coupling according to the national standard 9119 in accordance with DIN EN 1329-1
