The hexagonal adaptor DN with external BSP and NPT threads on both sides ensures reliable and leak‑tight connections between pipes, hoses with fittings, and diverse components of industrial installations operating under pressures reaching several dozen bar. Manufactured from high‑grade AISI 316 stainless steel, it guarantees durability, corrosion resistance, and long service life even in demanding environments. For processes involving highly aggressive chemicals, the adaptor can be supplied with an advanced ECTFE fluoropolymer coating that provides exceptional chemical resistance, or in a conductive CF‑ECTFE version (R <10⁶ Ω) designed to safely dissipate electrostatic charges. Depending on the selected size, material, and manufacturer, the couplings are available with different flange shapes adapted for easy tightening with a wrench, ensuring quick installation and secure operation. This versatile solution is ideal for industries requiring maximum safety, reliability, and resistance to extreme working conditions.
