What are push-to-connect fittings?

A push-to-connect fitting is a universal pipe fitting that is installed without the use of special tools. This type of fitting is also called a push-fit, push-in or push-fit connector, and fits to locks by the use of pressure inside the plumbing system. Soldering, crimping and glueing are not required with push-to-connect fittings. So, to find out more about push to connect fittings, including their benefits, continue reading our helpful guide.

Which applications use push-to-connect fittings?

Push-to-connect fittings are ideal for a wide range of applications, including potable water (also known as drinking water), plumbing, water heaters and hydronic heating systems. They can also be used in both new residential and commercial constructions, and are found in all new plumbing and dry repairs of existing plumbing.

Push-to-connect fittings are great for use with wet repairs where a system is difficult to drain. They’re also used in hazardous locations. No heat or flame is required to install them so push-to-connect fittings work well for repairs on systems or in environments that pose a potential fire risk.

Are push-to-connect fittings permanent?

Most push-to-connect fittings are authorised to be used for in-wall or underground applications, as well as permanent installations. However, many plumbers still prefer soldering over push-to-connect fittings because it provides a more secure and permanent connection. 

However, push-to-connect may well be a good option for your application, and can be used as a permanent solution.

Benefits of push-to-connect fittings

What are the benefits of a push-to-connect fittings then?

• Fast and reliable connections without the use of glue, solder or clamps.
• The tubing does not need to be completely dry, unlike fittings that require glue or solder.
• Push-to-connect fittings are available in a variety of materials for different applications to match the corresponding tube or pipe.
• Easily detached to help with inserting new tubing or performing general maintenance. A permanent, soldered fitting would be a lot more difficult to remove.

Are there any disadvantages to push-to-connect fittings?

Of course, push-to-connect fittings are not perfect. They do have a couple of disadvantages in comparison to other fittings, like soldered or compressed.

For example, they typically cost more than a compression fitting. They provide a reliable and easy installation but that comes at a cost. If money is no issue to you with your particular application, then a push-to-connect fitting could be for you.

Also, despite their reliability, they are still not as strong a fitting as one that has been soldered into place.

How to apply push-to-connect fittings

1. Identify your pipe material. PEX, Copper, CPVC, PE-RT, and SDR-9 HDPE pipe are all compatible with most push-to-connect fittings.
2. Check for scratches or debris on the pipe and cut it clean and square. Remove sharp edges on the copper pipe with a deburring tool. If you fail to correctly deburr the pipe, it can affect the fitting and create leaks.
3. Measure and mark on the pipe where you will insert the push-to-connect fitting.
4. Insert the fitting into the pipe at the point you made an insertion. Ensure that it is snug and secure, turn on the water and double check the connection for leaks.

How to disconnect a push-to-connect fitting

1. Turn off the water supply in the property. This prevents any excess water leakage which could lead to damage.
2. Figure out the type of fitting you’re going to be removing. The most common pipe fittings are speedfit fittings, brass fittings, and copper fittings.
3. Remove the fitting with your preferred tool by pinching the fitting in the proper location and allowing it to slide away from the pipe.
4. Disconnect the clips. You should have a horseshoe-shaped tool that fits over the pipe, engaging the pipe’s disconnecting lugs, which allows the pipe to be removed.
