In daily life, PEX tubes have been widely used, people choose more brass fittings as PEX tubes than plastic fittings, mainly because of the following points.
Mechanical property
Copper has excellent mechanical properties. Can withstand pipe pressure and prevent water corrosion. In contrast, plastic connectors may have aging, embrittlement, water leakage and other risks, and their service life is relatively short.
Corrosion resistance
Copper has good corrosion resistance. It can maintain its original performance for a long time and will not be damaged by environmental factors. Plastic connectors may be corroded by chemicals, affecting their performance and service life.
Thermal conductivity
Copper has excellent thermal conductivity. Better ability to transfer water heat to radiators or underfloor heating systems. This helps to improve the thermal efficiency of the system and achieve better heat dissipation.
Connection firmness and tightness
The connection of PEX tubes to brass fittings requires the use of special metal connectors. Such as copper inserts or metal threaded joints, etc., to ensure the fastness and tightness of the connection. These metal connectors can adapt to the various requirements of the pipeline and ensure the sealing and stability of the connection site.
To sum up
The reason why PEX tubes use copper fittings instead of plastic fittings is mainly because copper has better mechanical properties, corrosion resistance, thermal conductivity, and connection firmness and sealing. These characteristics can ensure that PEX tubes are more stable, reliable and safe during use, and improve the service life and performance of the system.
