They are widely used to connect copper pipes, offering a secure and leak-proof joint without the need for welding or soldering.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Materials You\u2019ll Need<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Copper pipe<\/li>\n\n\n\n<li>Compression fittings (comprised of a nut, ferrule, and fitting body)<\/li>\n\n\n\n<li>Pipe cutter or hacksaw<\/li>\n\n\n\n<li>Deburring tool (or file)<\/li>\n\n\n\n<li>Wrench<\/li>\n\n\n\n<li>PTFE tape (optional)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Measure and Cut the Copper Pipe<\/h3>\n\n\n\n<p>Begin by determining the length of the <a href=\"https:\/\/www.c-flo.com\/copper-pipes-tubes-manufacturer-supplier.html\">copper pipe<\/a> that needs to be installed. Use a pipe cutter or hacksaw to cut the copper pipe to the desired length. It&#8217;s crucial that the cut is clean and square to ensure proper fitting. When using a hacksaw, make sure to cut straight and avoid any damage to the pipe edges.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Deburr the Edges<\/h3>\n\n\n\n<p>After cutting the pipe, use a deburring tool or file to smooth out the edges. Deburring is necessary to eliminate any sharp edges or burrs that might damage the compression ring or cause an improper seal. A clean, smooth edge ensures the fitting will slide easily onto the pipe.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"730\" height=\"420\" src=\"https:\/\/www.c-flo.com\/blog\/wp-content\/uploads\/2025\/01\/Compression-Fittings.jpg\" alt=\"Compression Fittings\" class=\"wp-image-378\" style=\"width:840px;height:auto\" srcset=\"https:\/\/www.c-flo.com\/blog\/wp-content\/uploads\/2025\/01\/Compression-Fittings.jpg 730w, https:\/\/www.c-flo.com\/blog\/wp-content\/uploads\/2025\/01\/Compression-Fittings-300x173.jpg 300w\" sizes=\"auto, (max-width: 730px) 100vw, 730px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Slide on the Compression Nut and Ferrule<\/h3>\n\n\n\n<p>Before attaching the compression fitting, slide the compression nut onto the pipe. Next, slide the ferrule onto the pipe as well. Ensure that the ferrule is placed at the pipe\u2019s end and that it is positioned correctly, as this will be the part that compresses to create a seal.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Insert the Pipe into the Compression Fitting<\/h3>\n\n\n\n<p>Now, insert the copper pipe into the compression fitting body. Make sure the pipe is fully inserted into the fitting, and the ferrule is positioned around the pipe end. The compression fitting body should be centered on the pipe.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 5: Tighten the Compression Nut<\/h3>\n\n\n\n<p>Using a wrench, begin tightening the compression nut onto the compression fitting body. As you tighten, the ferrule will compress around the copper pipe, creating a tight, secure seal. Be sure not to over-tighten, as this can damage the ferrule or the pipe. A snug, firm fit is usually sufficient.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 6: Check for Leaks<\/h3>\n\n\n\n<p>Once the compression nut is tightened, check the connection for leaks. If you notice any, slightly tighten the compression nut a bit more. You can also apply PTFE tape around the pipe end before installing the fitting, as it can help prevent leaks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Tips for Success:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Always use the correct size compression fitting for the copper pipe to ensure a proper seal.<\/li>\n\n\n\n<li>When working with older copper pipes, check for any damage or corrosion before installing the compression fittings.<\/li>\n\n\n\n<li>If using compression fittings in a high-pressure system, consider using additional sealing methods or consult with a professional plumber.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion<\/h3>\n\n\n\n<p>Using compression fittings on copper pipes is a straightforward and effective method for creating secure, leak-proof connections. By following the above steps and tips, you can ensure a high-quality installation that will last for years.
