How to Join Brass Pipe

If you’re looking to join two pieces of brass pipe, you can use a few different methods. Each method has advantages and disadvantages, so it’s important to consider the context before deciding. In this blog post, we’ll look at how to join two pieces of brass pipe using solder, compression fittings, and threaded pipe connectors.

Soldering Brass Pipe

Soldering is one of the most common methods for joining two brass pipe pieces. The process involves melting lead-free solder onto the end of the pipes and then allowing them to cool and harden. To begin soldering, you’ll need a propane torch, flux paste, sandpaper or steel wool, and lead-free solder. First, clean both ends of the pipe with sandpaper or steel wool to remove any dirt or debris that could prevent the pipes from sealing correctly. Then apply flux paste to both ends of the pipe and attach them. Next, hold your torch against the joint while slowly running lead-free solder along it until it melts completely around the entire circumference of the joint. Once this is done, allow the joint to cool before testing it for leaks.

Using Compression Fittings

Compression fittings are an alternative for joining brass pipes without solder or heat. These fittings consist of a nut that screws onto one end of each tube and compresses them together when tightened. To install these fittings correctly:

  • Wrap some teflon tape around each thread on the outside surface of each tube’s end to create a seal between them when they are connected later.
  • Place one nut onto each thread and slide them against each other so that their compressing rings align when connected later.
  • Screw both nuts onto their respective threads until they meet in the middle, and tighten them with an adjustable wrench or pliers until they are tight enough that no more leaking occurs from around either side of the connection point.

Threaded Pipe Connectors

Threaded pipe connectors offer yet another alternative option for joining brass pipes without using solder or heat, as well as compression fittings. These connectors are threaded into place using a wrench or pliers until they form a tight seal between both ends of the pipe being joined together. To install these connectors properly, wrap some teflon tape around each thread on either side before connecting them to ensure that no leaking occurs at either end after installation is complete.


Joining two pieces of brass pipe requires careful consideration based on many factors, such as cost, ease of use, reliability etc. Depending on your needs, several options are available for joining brass pipes, including soldering, compression fittings, and threaded connectors, which can provide reliable joints depending on your situation.
