Different Properties of PEX and PVC

PEX (cross-linked polyethylene) and PVC (polyvinyl chloride) are two widely used materials in plumbing and construction. While they both have their own advantages and applications, there is one significant difference between them when it comes to installation: the ability to be glued.

PVC pipes are renowned for their rigidity and are often joined together using solvent cement or adhesive glue. The solvent cement softens the PVC material, allowing for a strong bond when the pieces are pressed together. This method has proven effective for PVC pipes, making it a popular choice among plumbers and DIY enthusiasts.

In contrast, PEX pipes cannot be glued using traditional PVC adhesive glue. This is due to the difference in chemical composition and surface properties of the two materials. PEX pipes have a smooth surface that does not allow adhesive glue to bond effectively. Furthermore, the chemical composition of PEX does not react with the solvent in PVC glue, rendering it ineffective for bonding PEX pipes.

So, if you can’t glue PEX like PVC, how do you join PEX pipes? The answer lies in mechanical fittings. PEX pipes are typically joined using crimp or clamp fittings. These fittings create a secure connection by compressing the pipe onto a metal ring or barb fitting. This method ensures a watertight seal and provides reliable connections.

Although there are specific adhesives available on the market designed for joining PEX pipes, it is generally recommended to use mechanical fittings instead. Mechanical fittings offer superior reliability and ease of installation compared to gluing PEX pipes.

Joining Methods for PEX and PVC

In the world of plumbing and construction, PEX and PVC pipes are like two superheroes with their own unique powers. PVC, the seasoned veteran, relies on adhesive glue to create strong connections. PEX, the newcomer, prefers the strength and reliability of mechanical fittings. Let’s take a closer look at these joining methods and discover which one reigns supreme.

PVC pipes have been saving the day in plumbing projects for years, thanks to their secret weapon: adhesive glue. This superhero glue, also known as solvent cement, combines adhesive and primer to soften the PVC pipe and fitting surfaces. When applied correctly, it creates a powerful bond that can withstand even the harshest conditions. But like any superhero power, adhesive glue has its limitations. It requires careful preparation and application for a successful bond. Plus, it takes time to dry and harden before the pipe can be used, which can slow down your project.

Now, let’s meet PEX pipes, the rising star in the plumbing scene. These flexible pipes boast durability and easy installation. When it comes to joining PEX pipes, mechanical fittings steal the show. These fittings come in different types: crimp fittings, clamp fittings, and push-fit fittings.

Crimp fittings involve using a special crimping tool to compress a metal ring over the PEX pipe and fitting. This creates a connection so secure it’s like a superhero’s unbreakable grip. Clamp fittings work similarly but use stainless steel clamps instead of metal rings. And then there are push-fit fittings – the true superheroes of PEX connections. With built-in O-rings, they create a tight seal when the PEX pipe is inserted into the fitting, without the need for any tools or additional materials.

But why can’t we just use glue for PEX pipes like we do for PVC? It’s all about chemistry. The chemical composition of PEX does not allow for solvent cement or glue to bond effectively with the material. Attempting to glue PEX can result in weak or unreliable connections that may fail over time. So, if you want to harness the full power of PEX pipes, stick to mechanical fittings.

Why Gluing PEX Like PVC is Not Recommended
