How to Install Compression Fitting on Plastic Tubing
Installing compression fittings on plastic tubing is a common task in various plumbing and piping applications. Compression fittings provide a secure and leak-proof connection between two plastic pipes. This article will guide you through the step-by-step process of installing compression fittings on plastic tubing.
Materials Needed
Before you begin, gather the following materials:
– Plastic tubing
– Compression fitting
– Tube cutter or hacksaw
– Pliers
– Pipe cleaner or sandpaper
– Lubricant (optional)
Step 1: Measure and Cut the Tubing
Start by measuring the length of plastic tubing required for your application. Use a tube cutter or hacksaw to cut the tubing to the desired length. Ensure that the cut is clean and perpendicular to the tubing’s axis.
Step 2: Clean the Tubing Ends
After cutting the tubing, clean the ends to remove any burrs or debris. You can use a pipe cleaner or sandpaper to achieve a smooth and clean surface. This step is crucial for a proper fit and to prevent leaks.
Step 3: Apply Lubricant (Optional)
If you’re using a lubricant, apply it to the outside of the tubing and the inside of the compression fitting. This will make the installation process easier and ensure a tight seal.
Step 4: Insert the Tubing into the Compression Fitting
Position the tubing over the compression fitting. Push the tubing into the fitting until it reaches the bottom of the compression nut. Make sure the tubing is fully seated and does not have any twists or kinks.
Step 5: Tighten the Compression Nut
Using pliers, gently tighten the compression nut onto the fitting. Ensure that the nut is tight enough to compress the stainless steel compression ring inside the fitting, but do not overtighten. Over-tightening can damage the tubing or fitting and lead to leaks.
Step 6: Check for Leaks
After installing the compression fitting, check for leaks by applying pressure to the connection. If you notice any leaks, loosen the nut slightly and retighten it. Repeat this process until the connection is leak-proof.
Conclusion
Installing compression fittings on plastic tubing is a straightforward process that can be completed in a few simple steps. By following this guide, you can ensure a secure and leak-proof connection for your plumbing or piping application. Always use the appropriate tools and materials to achieve the best results.
