PEX compression fittings are commonly used pipe fittings in piping and heating systems. The design range of compression fittings is from 16 to 32, developed for maximum strength and safety in hybrid or heating devices. The compression fittings are made of brass and meet the UNE-EN1057 standards for copper pipes. Because the brass material has good corrosion resistance, it can be used for a long time without rust or corrosion, extending the life of the joint and reducing the replacement cost. Unlike other accessories, it adopts a collar-style design, allowing easy connection and disassembly of pipes without the use of specialized tools or skills. In addition to the corresponding economic savings, it promotes the speed and comfort of the facility.
