As a sommelier and brewer, my expertise lies in the world of wines and beers. However, I can still provide some insight into using a crimp clamp, which is commonly used in plumbing and specifically for PEX connections.
Using a crimp clamp can be a bit tricky if you're working in tight spaces or if the PEX is pressed up against a wall. Unlike pinch clamp tools, crimp tools have larger jaws, which require more room behind the PEX to make a proper connection. But fear not, I'll guide you through the process step by step.
1. Prepare the PEX pipe: Before you begin, ensure that your PEX pipe is cut to the appropriate length and deburred. Deburring involves removing any rough or sharp edges from the cut end of the pipe, as this can affect the integrity of the connection.
2. Choose the right crimp ring size: Crimp rings come in different sizes, so it's important to select the appropriate one for your PEX pipe size. The crimp ring should fit snugly around the pipe without any gaps or overlaps.
3. Slide the crimp ring onto the pipe: Place the crimp ring onto the end of the PEX pipe, ensuring it is positioned close to the edge but not too close that it slips off when crimping.
4. Insert the fitting: Insert the fitting into the end of the PEX pipe, making sure it goes all the way in until it reaches the shoulder of the fitting. This ensures a proper connection.
5. Position the crimp tool: Hold the crimp tool perpendicular to the PEX pipe, ensuring the jaws are centered over the crimp ring. Make sure you have enough space behind the PEX pipe to allow the jaws to close fully.
6. Crimp the ring: Squeeze the handles of the crimp tool firmly and evenly until the jaws close completely. This compresses the crimp ring and secures the fitting to the PEX pipe. Be mindful not to over-crimp, as this can damage the connection.
7. Inspect the connection: After crimping, visually inspect the connection to ensure the crimp ring is properly compressed around the pipe and fitting. There should be no gaps or deformities. You can also perform a pressure test to check for any leaks.
8. Repeat the process: If you have multiple connections to make, repeat the above steps for each one. Take your time and ensure each crimp is done correctly to avoid any issues down the line.
It's worth noting that crimp clamps are typically one-time use, meaning you can't remove and reuse them. Once crimped, they provide a reliable and secure connection. If you need to remove a crimped connection, you would have to cut the PEX pipe and start fresh with a new fitting and crimp ring.
In my experience, using crimp clamps can be a bit challenging in tight spaces. It's important to have enough room behind the PEX pipe to allow the crimp tool to work effectively. If you find yourself in a particularly difficult space, you might consider using pinch clamps instead, as they can be more maneuverable.
Using a crimp clamp involves selecting the appropriate size crimp ring, sliding it onto the PEX pipe, inserting the fitting, positioning the crimp tool, and crimping the ring securely. Take your time, inspect your connections, and ensure a proper fit to avoid any plumbing mishaps.
