Crimping compression fittings is a straightforward process that involves using a specialized tool to secure the fitting onto a pipe. Here's a step-by-step guide:
1. Prepare the Pipe and Fitting
- Cut the pipe to the desired length using a pipe cutter or hacksaw.
- Deburr the cut end of the pipe to remove any sharp edges that could damage the fitting or cause leaks.
- Apply thread sealant tape or pipe dope to the threads of the fitting to prevent leaks.
2. Assemble the Fitting
- Insert the pipe into the fitting until it reaches the stop.
- Ensure that the pipe is fully seated in the fitting before proceeding.
3. Crimp the Fitting
- Use a compression crimping tool designed for the size of the fitting.
- Place the jaws of the crimping tool around the fitting's compression nut and tighten the tool until the nut is fully crimped onto the pipe.
- The crimping tool will compress the nut, creating a tight seal between the pipe and the fitting.
4. Inspect the Connection
- After crimping, check for any leaks by applying pressure to the pipe.
- If there are any leaks, tighten the nut slightly using a wrench.
- If the leaks persist, you may need to re-crimp the fitting or replace it.
5. Tips for Success
- Use the right size of crimping tool for the fitting.
- Ensure that the pipe is fully seated in the fitting before crimping.
- Apply even pressure when crimping to ensure a tight seal.
- Always inspect the connection for leaks after crimping.
Crimping compression fittings is a relatively simple process, but it's crucial to follow the steps carefully to ensure a leak-proof connection. By using the right tools and techniques, you can create a secure and reliable pipe system.
