Whether you are a professional plumber or a DIY enthusiast, this step-by-step tutorial will equip you with the knowledge you need to get the job done right.

What are Compression Fittings?

Compression fittings are plumbing components designed to create a secure and leak-free connection between pipes or tubes. They consist of several parts, including a compression nut, a compression ring (ferrule), and a fitting body. The compression nut is responsible for compressing the ferrule onto the pipe, creating a tight seal.

How to Install Compression Fittings?

  • Gather the Required Tools and Materials

Before you begin the installation process, make sure you have the necessary tools and materials at hand. These typically include:

Compression fitting components: This includes the fitting body, compression nut, and compression ring (also known as the ferrule fittings).

Pipe or tubing: Ensure you have the appropriate type and size for your specific application.

Pipe cutter or hacksaw: Used to cut the pipe or tubing to the desired length.

Deburring tool: Helps remove any burrs or sharp edges from the cut pipe.

Adjustable wrenches: Required for tightening the compression nut.

  • Cut the Pipe or Tubing

Measure and mark the pipe or tubing to the desired length using a tape measure or ruler. Once marked, use a pipe cutter or hacksaw to make a clean and precise cut. Ensure that the cut is perpendicular to the pipe to ensure a proper fit.

  • Deburring the Pipe

Once the pipe has been cut, use a deburring tool to remove any burrs or sharp edges. This step is crucial as it helps prevent damage to the compression fitting components and ensures a smooth connection.

  • Slide on the Compression Nut and Ring

Slide the compression nut and compression ring onto the pipe, with the threaded side of the nut facing outwards. Ensure that the compression ring is placed evenly and snugly against the pipe.

  • Insert the Pipe into the Fitting Body

Insert the cut end of the pipe into the fitting body until it reaches the shoulder inside the fitting. Make sure the pipe is fully inserted and that it aligns properly with the fitting body.

  • Hand-Tighten the Compression Nut

With the pipe in place, use your hands to tighten the compression nut onto the fitting body. Begin by turning the nut clockwise, applying gentle pressure until it is snug. Avoid overtightening at this stage.

  • Final Tightening with Adjustable Wrenches

Using two adjustable wrenches, hold the fitting body steady while tightening the compression nut with the other wrench. Apply equal pressure to ensure a secure and leak-free connection. Remember not to overtighten, as it may damage the fitting or cause leaks.

  • Check for Leaks

Once the compression fitting is securely tightened, turn on the water supply to check for any leaks. Inspect the connection carefully, looking for any signs of dripping or seepage. If any leaks are detected, gently tighten the compression nut until the leak stops.
