Nov 17, 2025

Quick-connect fittings are highly practical in many applications, and their installation and maintenance in pipe and fitting systems are extremely simple. Thanks to their ease of use and convenient installation, quick-connect fittings are widely used. But how do you properly remove a quick-connect fitting? Improper removal methods can cause serious damage to the fitting, or even break it entirely. Read this practical guide provided by Fluid Controls to find the answer.

What Is a Push To-Connect Fitting?

Push-to-connect fittings (also known as quick connects or one-touch fittings) are a type of quick-connect widely used in piping systems, making pipe installation and maintenance simple and efficient.

These fittings are suitable for a variety of pipe materials, including PEX, PVC, CPVC, copper, stainless steel, and plastic hoses. They are commonly used in domestic water supply systems, building water supply and drainage, HVAC systems, pneumatic piping, equipment lines, and temporary or quick-dismantling piping networks.

Push-to-connect fittings typically consist of a fitting body, a sealing O-ring, and a locking retainer. During installation, simply push the pipe directly into the fitting; the retainer securely grips the pipe wall, and the O-ring provides a reliable seal, ensuring no leakage of fluid within the pipe. Push-to-connect couplers have become the ideal choice for modern piping installation and maintenance.

How to Remove Push To Quick Connect Fittings In Plumbing?

Removing push-to-connect fittings is usually simpler than installing them, but the method must be correct, otherwise you may damage the fitting or pipe. The following steps cover common tools, alternative methods, and techniques for dealing with stubborn fittings.

1. Using a Specialized Removal Tool

This small plastic or metal tool can grip the fitting and easily compress the release ring, thus unlocking the retaining ring inside the fitting.

Steps: Clamp the removal tool around the pipe and press it firmly against the release ring of the fitting. Press the tool against the fitting, forcing the release ring to retract. Simultaneously, gently pull the pipe outwards.

2. Using a Wrench or Pliers to Compress the Retaining Ring

If you don't have a specialized tool, you can also use an adjustable wrench, pump pliers, or pliers to compress the clamp or black plastic ring of the fitting.

Steps:

Firmly press the black or white retaining ring with pliers or a wrench.

Push the retaining ring back towards the fitting, causing the internal gripping teeth to release the pipe.

Simultaneously, use your other hand to pull the pipe out.

Suitable for situations where specialized tools are unavailable, there is sufficient pipe space, and the retaining ring is not severely damaged.
