Technical Comparison of Mono-layer (PEX) and Multi-layer (PEX-AL-PEX) Piping System for Water and Gas Applications

The two types of PEX piping systems, mono-layer PEX and multi-layer PEX-AL-PEX offer distinct advantages and disadvantages for water and gas applications. According to industry experts, mono-layer PEX is a cost-effective option for residential and commercial water distribution systems. Its flexibility and ease of installation make it an attractive option for those seeking a simpler installation process. However, it cannot be used for gas applications and is susceptible to damage from UV rays.
