Black Malleable Iron Coupling 3/4″
A leak-proof, corrosion-resistant threaded connection for demanding industrial piping systems.
The Black Coupling 3/4″ is a durable industrial pipe connection element designed to join two threaded pipes or fittings. In addition, it is manufactured from cast iron using a high-pressure casting method. Moreover, its black corrosion-protective coating forms an effective barrier against rust and oxidation. Furthermore, the internal threads conform to standard BSP or NPT profiles and mate perfectly with male-threaded pipes.
During installation, the pipe end is inserted into the coupling and tightened by turning clockwise. Consequently, this mechanical locking guarantees liquid and gas tightness. The coupling withstands a maximum working pressure of 25 bar and a maximum working temperature of 120°C. Its DN20 size and TS EN 10226 conformity make it suitable for a wide range of industrial piping systems.
