Which plumbing joint allows for easier disassembly?

A compression joint is specifically designed for ease of disassembly, making it the best choice among the options provided. Compression fittings consist of a few simple parts: a body, a compression ring (or ferrule), and a nut. When the nut is tightened onto the body, it compresses the ring against the pipe, forming a seal that does not require permanent attachment methods like soldering or welding.

This type of joint can be easily undone by simply loosening the nut, allowing for quick removal or replacement of the connected pipe or fitting. It is particularly advantageous in situations where maintenance or adjustments are necessary, as it does not require cutting or damaging the pipes to disassemble.

In contrast, solder joints require heat to melt the solder and create a permanent bond, making them difficult to disassemble without cutting the pipes. Welded joints are even more permanent, as they involve melting the metal to fuse two pieces together, which makes disassembly quite challenging. Epoxy joints use adhesive bonding, which also results in a permanent connection that typically cannot be disassembled easily without damage.

By understanding the functionality and characteristics of various joint types, it becomes clear that compression joints are the preferred option for applications where ease of disassembly is essential.
