What materials do I need to connect copper pipe to compression fitting?
To connect copper pipe to compression fitting, you will need a few essential materials and tools. First, you will need the copper pipe itself, which can vary in diameter depending on your plumbing requirements. You will also require a compression fitting that matches the diameter of the copper pipe and is suitable for your specific application, such as water supply or heating.
In addition to the pipe and fitting, you will need basic tools including a pipe cutter, adjustable wrench, and a deburring tool. The pipe cutter will ensure you achieve a clean cut for a proper fit, while the deburring tool will help smooth out any sharp edges on the cut copper to prevent damage to the compression fitting. It’s also beneficial to have some plumber’s tape or joint compound on hand for an added seal, though it’s not always necessary for compression fittings.
How do I prepare the copper pipe before connecting it to the compression fitting?
Preparing the copper pipe before connecting it to the compression fitting is a crucial step for ensuring a secure and leak-free joint. Begin by measuring the length of copper pipe you need and cutting it using a pipe cutter.
