The RS reducing adaptor is a versatile and durable solution designed for reliable connection of pipes, hoses with fittings, and components within industrial installations operating under pressures reaching several dozen bar. Engineered with internal and external BSP, NPT, and trapezoidal threads, it ensures compatibility with a wide range of systems and applications. Suitable for transporting diverse media such as water, air, chemical agents, and petrochemical products, it provides exceptional flexibility in demanding environments. For installations handling highly aggressive chemicals, the adaptor is available with an advanced ECTFE fluoropolymer coating that guarantees outstanding chemical resistance, while the CF-ECTFE conductive version (R <10⁶ Ω) offers additional safety in processes requiring electrostatic discharge protection. Depending on size and manufacturer, the couplings feature different flange shapes adapted for wrench tightening, ensuring ease of assembly and secure installation. Manufactured from premium AISI 316 stainless steel, the adaptor delivers excellent corrosion resistance and long service life, even in harsh conditions. The sealing system is based on a flat PTFE gasket (BSP GW), providing reliable tightness and minimizing the risk of leakage. This combination of robust materials, advanced coatings, and precise engineering makes the RS reducing adaptor an optimal choice for industries seeking efficiency, safety, and durability in fluid handling systems.
