What Glue Sticks To PEX? It’s no secret that PEX is becoming one of the most popular plumbing materials on the market. But many people need to learn that various types of glue can be used with PEX pipe.

This blog post will cover a few of the most popular glue options and their benefits. So, whether you’re a new homeowner or a seasoned contractor, read on to learn more about what glue sticks to PEX!

What Is PEX?

PEX piping is an alternative to copper and galvanized pipes. The newer, more popular choice for DIYers who want their projects done fast with no hassle in new construction or when replacing old stock throughout your home’s plumbing system

PEX is short for cross-linked polyethylene. The plastic piping type is commonly used for plumbing and radiant heating applications. PEX is available in various sizes, ranging from 1/4 inch to 4 inches in diameter.

It is also available in various colors, which can identify different types of piping or indicate the water temperature in a given system. PEX is typically white or light blue but can also be found in red, green, and black.

PEX is flexible, making it easy to work with and resistant to freezing and bursting. It can also withstand high temperatures, making it an ideal choice for hot water applications. PEX is durable and long lasting and does not corrode like metal pipes.

What Are The Different Glue Types

There are many different types of glue, each with unique properties and uses. Here is a quick rundown of some of the most common types of glue:


Cyanoacrylate, also known as super glue, is a fast-drying adhesive made from acrylic monomers. It is frequently used in household applications and can bond metal, glass, plastic, and ceramic. However, it is not recommended for use on porous surfaces such as paper or wood.

PVA (Polyvinyl acetate)

PVA glue, also known as white glue or wood glue, is a synthetic polymer adhesive. It is water-soluble when wet but dries clear and hard. PVAs are commonly used in woodworking and bookbinding. They can be used on porous surfaces such as paper and fabric and non-porous surfaces such as metal and glass.

Polyurethane adhesives

Polyurethane adhesives are strong, flexible, and durable adhesives that can be used on various materials, including wood, metal, ceramic, glass, and plastics.

They are commonly used in construction applications. Polyurethane adhesives come in two forms: one-part adhesives that cure at room temperature and two-part adhesives that require mixing before use.


Epoxies are synthetic resins that come in two parts: a resin and a hardener. They create a strong bond that can withstand extreme temperatures and heavy loads when mixed.

Epoxies can be used on metals, glass, ceramics, concrete, and most plastics. They are frequently used in electronics applications where circuitry needs to be securely bonded to a heat sink.

Craft glues

Craft glues are water-based adhesives designed for use with paper products. They come in both liquid and paste form and dry clear. Common craft glues include rubber cement, mucilage (a paste type), and decoupage glues. Craft glues are safe for children and easily cleaned up with water if accidental spills occur.

Why Choose A Glue That Sticks Well To Your PEX?

Choosing the right glue is important because not all adhesives are compatible with PEX. Incompatible glues can cause the repair to fail or result in other problems, such as poisoning the water supply. That’s why it’s always best to use glue that has been specifically designed for use with PEX pipe.

PEX pipe is made from cross-linked polyethylene, a type of plastic treated with chemicals to create stronger bonds between its molecules.

This process makes PEX more resistant to temperature changes and breaking than regular polyethylene pipes.

PEX is also more flexible than other pipe types, making it easier to install in tight spaces. These properties make PEX an ideal choice for plumbing and radiant heating systems.

PEX pipe repairs are best made using glue specifically designed for this material. It is because not all adhesives are compatible with PEX, and using an incompatible adhesive can cause the repair to fail or result in other problems.

For example, some adhesives contain chemicals that can react badly with PEX, causing the pipe to break down over time. It can lead to expensive repairs or even complete piping system replacement. In extreme cases, using the wrong adhesive can poison the water supply.

That’s why it’s always best to use an adhesive that has been specifically designed for use with PEX pipe. These glues provide a secure and lasting repair that won’t cause any long-term damage to the piping system.

How To Choose The Right Glue For Your PEX

Three main types of adhesives can be used on PEX piping: epoxy, polyurethane, and acrylic.

Epoxy adhesives are the strongest type of adhesive and create a permanent bond. They are typically used in repair work and are not recommended for PEX piping.

Polyurethane adhesives create a strong, flexible bond and are often used in construction projects. They can be used with PEX piping but should only be applied to joints that will not need to be moved after the adhesive has dried.

Acrylic adhesives create a strong bond and are flexible enough to allow for some movement after the adhesive has dried. It makes them ideal for use with PEX piping. Acrylic adhesives come in two forms: liquid and gel. The liquid form is easier to apply but has a shorter bonding time than the gel form.

When choosing an adhesive, you will also need to choose between solvent-based and water-based adhesives. Solvent-based adhesives have a shorter drying time but release harmful VOCs into the air. Water-based adhesives have a longer drying time but do not release VOCs.

Can You Use Glue On PEX?

While traditional plumbing materials like copper and PVC require soldering or gluing for a watertight connection, PEX pipes can be pushed together with specialized fittings.

It makes them much easier to work with, particularly for do-it-yourselfers, and eliminates the need for messy and potentially dangerous chemicals. The reliability of the seal is also increased, as there is no risk of the joint coming apart if it’s not installed correctly.

PEX pipes are less likely to develop leaks over time, making them a great choice for new construction and repairs. So, if you’re looking for an easier and more reliable option, go with PEX!

What Glue Sticks On PEX?

Pex is a great material for plumbing because it is durable and easy to work with. However, to make the most of your Pex, you need to use a special fitting known as an “insert.” The two types of inserts commonly used in the installation are glue connections and threaded connections.

Glue connections are made by applying a special adhesive to the end of the Pex tubing and then inserting it into the fitting. Threaded connections are made by screwing the fitting onto the end of the Pex tubing. For best results, try using 3M’s DP-8005 adhesive!

Does PVC Glue Sticks On PEX?

PVC glue sticks to PEX piping because of the adhesive qualities of the epoxy. The epoxy creates a bond between the PVC and the PEX, which helps to prevent leaks and strengthen the connection between the two materials.

While PVC glue is not required for PEX piping, it can be used to create a stronger connection or to seal any gaps that may exist between the two materials.

In addition, PVC glue can help to prevent corrosion and degradation of the PEX piping over time.

Does Epoxy Sticks To PEX?

Epoxy is an adhesive often used for bonding metal, glass, and plastic. It is also sometimes used for joining dissimilar materials, such as concrete and wood. PEX is the plastic type often used in plumbing and electrical applications. It is durable and resistant to both heat and chemicals. When the epoxy is used to bond PEX, it creates a strong and durable joint that can withstand great stress.

Epoxy helps to protect the PEX from being damaged by chemicals or heat. Then, epoxy is an ideal choice for bonding PEX.

How Long Will PEX Last?

PEX is a remarkably durable piping material with an expected lifespan of 50 years or more under typical conditions. It makes it an excellent choice for plumbing, particularly in homes where extreme temperatures are not common.

PVC and CPVC also have lifespans of around 40-50 years, but it is important to note that these pipes were primarily designed for drainage purposes. For this reason, they are not always used in locations where extreme heat might occur – such as near radiant heating systems.

PEX is a much more versatile material that can withstand a high-temperature range, making it ideal for various settings.

Ultimately, deciding which piping material to use should be based on the project’s specific needs. But if longevity is a top priority, PEX is a clear winner.
