Can push fit pipe fittings be used with polyethylene pipes?

Push fit pipe fittings are a popular choice for many DIY enthusiasts and professionals alike. They are easy to install, require no special tools or skills, and are generally very reliable. One question that often arises is whether push fit pipe fittings can be used with polyethylene pipes. In this article, we will explore this topic in detail, discussing the properties of polyethylene pipes and push fit fittings, as well as the advantages and disadvantages of using them together.

Polyethylene Pipes

Polyethylene (PE) pipes are widely used in many applications due to their excellent chemical resistance, low weight, and flexibility. They are commonly used in water supply and distribution systems, as well as in gas distribution networks. PE pipes are available in various sizes and thicknesses, and they can be used in both buried and above ground applications.

PE pipes are made from a thermoplastic polymer called polyethylene. This material is chemically resistant to a wide range of substances, including acids, alkalis, and organic solvents. It is also highly resistant to corrosion and has excellent electrical properties. Additionally, polyethylene is a lightweight material that is easy to handle and transport.

PE pipes are typically produced in two forms : high density polyethylene (HDPE) and low density polyethylene (LDPE). HDPE pipes are more commonly used due to their higher strength and durability. They are suitable for use in temperatures ranging from 40°C to 60°C and can withstand pressures up to 16 bar. LDPE pipes, on the other hand, are more flexible and are often used for irrigation and other low pressure applications.

Push Fit Pipe Fittings

Push fit pipe fittings, also known as push to connect fittings, are a type of plumbing fitting that is designed to be easy to install and remove without the use of special tools. They are typically made from brass or other metals, although plastic push fit fittings are also available.

Push fit fittings work by using a series of O rings and other seals to create a tight and secure connection between the fitting and the pipe. The fittings consist of two parts : the body and the locking mechanism. The body contains the O rings and seals, while the locking mechanism locks the fitting onto the pipe and provides a secure connection.

Advantages of Using Push Fit Pipe Fittings

There are several advantages to using push fit pipe fittings. These include :

  1. Easy installation : Push fit fittings can be installed quickly and easily without the use of special tools or equipment. This makes them a popular choice for DIY enthusiasts and professionals alike.

  2. No soldering or gluing required : Unlike other types of fittings, such as soldered or glued fittings, push fit fittings do not require any additional materials or equipment. This saves time and reduces the risk of errors during installation.

  3. Reliable connections : Push fit fittings use a series of O rings and other seals to create a tight and secure connection between the fitting and the pipe. This helps to prevent leaks and ensures a reliable connection.

  4. Reusable : Push fit fittings can be easily removed and reused, making them a cost effective choice for many applications.

Disadvantages of Using Push Fit Pipe Fittings

While push fit pipe fittings offer many advantages, there are also some disadvantages to consider. These include :

  1. Limited compatibility : Push fit fittings may not be compatible with all types of pipes, including certain types of plastic pipes.

  2. Limited temperature and pressure ratings : Push fit fittings may not be suitable for use in high temperature or high pressure applications.

  3. Limited availability : Push fit fittings may not be available in all sizes or configurations, which can limit their use in certain applications.
