How To Remove a PEX Crimp Ring Without a Specialized Tool: A DIY Guide

In DIY plumbing, dealing with PEX (cross-linked polyethylene) tubing can sometimes mean removing a crimp ring, especially if you don’t have the specific tool designed for this task. Whether you’re correcting a mistake or altering your plumbing setup, knowing how to remove a PEX crimp ring without a specialized tool can be handy.

This article guides you through the process simply and straightforwardly, ensuring you can confidently tackle this task.

What is a PEX Crimp Ring, and Why Remove It?

Before diving into the removal process, it’s important to understand what a PEX crimp ring is and why you might need to remove it.

What are PEX Crimp Rings?

PEX crimp rings are small metal bands used in plumbing with PEX (cross-linked polyethylene) pipes. They slide over the PEX pipe and are crimped using a specialized tool, creating a secure connection with fittings.

These rings provide a reliable, watertight seal and are commonly used in residential and commercial plumbing installations.

Why Remove It?

Removing a PEX crimp ring may be necessary in cases of leaks, incorrect positioning, or when replacing or repositioning PEX tubing. If the joint isn’t sealed properly, the ring can be carefully cut or pried off using appropriate tools.

This allows for adjustments or replacements to be made to ensure a secure and leak-free connection in plumbing applications.

How Can You Identify the Need for Removal?

Detecting the need to remove a PEX crimp ring involves key observations. If you detect leaks around the joint, it signals a potential issue, necessitating removal for inspection or replacement. Incorrect positioning of the ring, visible misalignment, or insecurity in the connection are additional signs.

Removal becomes essential if you need to adjust or replace the PEX tubing. Conduct a thorough visual examination, checking for any irregularities in the crimped area. If uncertainty or issues arise, it’s advisable to address them promptly to ensure the integrity of the plumbing system.

Step-by-Step Guide to Removing a PEX Crimp Ring

Removing a PEX crimp ring without a specific tool involves a few steps that must be carried out carefully to avoid damaging the PEX pipe.

1. Gather Your Tools:

• Equip yourself with a sharp utility knife or a small hacksaw for cutting, a flat-head screwdriver, and needle-nose pliers for prying.

2. Identify the Crimped Area:

• Locate the PEX crimp ring on the joint that needs removal. Ensure there is enough space to work without damaging surrounding components.

3. Cut the Crimp Ring:

• With your utility knife or hacksaw, carefully cut through the crimp ring. Exercise caution to avoid cutting too deep, minimizing the risk of damaging the PEX pipe.

4. Assess the Cut:

• Inspect the cut to ensure it’s complete and has penetrated through the entire circumference of the crimp ring.

5. Create a Gap:

• After cutting, use the flat-head screwdriver. Insert it into the cut you’ve made and gently pry the ring open. Apply even pressure to create a gap in the ring.

6. Alternative Method with Pliers:

• Alternatively, use needle-nose pliers to grip the cut section of the crimp ring. Twist the pliers to create an opening and carefully pull the ring apart.

7. Gradual Removal:

• Work gradually around the crimped area, prying or twisting to expand the gap until the ring can be removed entirely.

8. Inspect the PEX Pipe:

• Once the crimp ring is off, inspect the PEX pipe for any damage. Smooth out any rough edges left by the removal process.

9. Proceed with Repairs:

• With the crimp ring removed, you can proceed with any necessary repairs or adjustments to the PEX tubing, ensuring a secure and watertight connection.

What can I use instead of a PEX crimping tool?

If you don’t have a PEX crimping tool, alternative methods exist to secure PEX connections. Two common alternatives include:

01. Cinch Clamps

Cinch clamps, pinch clamps, or stainless steel clamps can be used with a cinch clamp tool. This tool differs from a crimping tool and is designed explicitly for cinch clamps.

It squeezes the clamp around the PEX tubing and fitting, creating a secure connection.

02. Copper Crimp Rings and Adjustable Wrench

Copper crimp rings are another option. While a proper crimping tool is ideal, you can use an adjustable wrench as an alternative.

Position the crimp ring over the PEX tubing and fitting, then use the adjustable wrench to compress the ring until it forms a secure connection.

Always follow the manufacturer’s guidelines for the specific PEX connection system you are using, and ensure that the alternative method you choose provides a reliable and watertight seal. It’s essential to use the appropriate tools and techniques to maintain the integrity of the plumbing system.

How do you remove a PEX crimp sleeve?

1. Gather Your Tools

• Obtain a mini-hacksaw and a flat-bladed screwdriver. Ensure you have a clear working space around the PEX crimp sleeve.

2. Identify the Crimp Sleeve

• Locate the PEX crimp sleeve on the joint that requires removal. Ensure there is enough space to work without damaging adjacent components.

3. Mark the Cut Area

• If feasible, mark the area on the crimp sleeve where you intend to cut. This helps ensure precision and avoids unnecessary damage to the PEX pipe.

4. Cut with the Mini-Hacksaw

• Use the mini-hacksaw to cut through the crimp sleeve carefully. Position the saw at a slight angle to create a groove, cutting almost all the way through the sleeve. Exercise caution to avoid damaging the PEX pipe beneath.

5. Confirm the Cut

• Inspect the cut to ensure it is complete and has penetrated most of the crimp sleeve.

6. Insert the Screwdriver

• Insert the flat-bladed screwdriver into the cut you’ve made. Use the screwdriver to twist and peel the crimp sleeve open gently. Apply even pressure to create a gap in the sleeve.

7. Gradual Removal

• Work gradually around the crimped area, using the screwdriver to peel the crimp sleeve off. Continue twisting and peeling until the sleeve can be removed entirely.

8. Inspect the PEX Pipe

• Once the crimp sleeve is off, inspect the PEX pipe for any damage. Smooth out any rough edges left by the removal process.

9. Proceed with Repairs

• With the crimp sleeve removed, you can proceed with any necessary repairs or adjustments to the PEX tubing, ensuring a secure and watertight connection.
