Installing copper pipe compression fittings is a straightforward process involving a few key steps. Here's a guide based on available information:
Preparing Your Copper Pipe
-
Cutting: Make sure the copper pipe is cut cleanly and squarely. Any burrs or uneven edges will impede proper sealing.
-
Cleaning: The pipe should be clean of any dirt or oxidation to allow the compression sleeve to form a tight seal.
Assembling the Compression Fitting
The core of the compression fitting involves three components that work together for a secure connection:
- Brass Nut: This is the first piece to slide onto the copper tubing.
- Slide the brass nut onto the tubing, ensuring the threaded portion is facing the direction of the intended connection.
- Compression Sleeve: Also known as a ferrule, this piece is crucial for creating the seal.
- Slide the compression sleeve onto the tubing, positioning it so it goes inside the brass nut and resting against the fitting.
- As referenced in the video titled, "How to Install Compression Fittings on Nylon and Copper Tubing", the sleeve slides down into the nut.
- Fitting Body: The fitting body is the part you are connecting the pipe to. It usually has a threaded part to receive the nut.
- Push the copper pipe with the nut and sleeve into the fitting body.
Securing the Connection
- Hand-Tightening: Screw the brass nut onto the fitting body by hand until it's snug.
- Wrench Tightening: Use two wrenches, one on the fitting body and one on the nut. Gently tighten the nut.
- Avoid over-tightening, as it can damage the fitting and the pipe and may cause leaks.
- Generally, 1/2 to 3/4 turn beyond hand-tight is sufficient.
- Check for Leaks: Turn on the water and check for leaks. If a leak is present, tighten the nut a tiny bit more.
- If the leak continues, disassemble and check components for damage.
Final Thoughts
Compression fittings are convenient for joining copper pipes without soldering, however they are not recommended for concealed locations. The mechanical connection can potentially fail in the future.
