Tees


Brass compression Tees are essential plumbing fittings used to create T-shaped connections in piping systems. These versatile components offer secure, leak-free joints without the need for soldering or specialized tools, making them ideal for both professional plumbers and DIY enthusiasts. These 90 degree Compression fittings and Compression pipe fittings are used worldwide for plumbing and HVAC applications.

 

Brass Compression Tees are essential components in plumbing, gas, and hydraulic systems. These fittings provide a secure and leak-proof connection between three pipes or tubes, making them ideal for applications requiring a branch connection. Due to their robust brass construction, they offer excellent corrosion resistance, durability, and long-lasting performance. They can be single ferrule or double ferrule compression Tee fittings.

 

Brass Compression fittings are mechanical fittings used to join pipes or tubes without welding or soldering. They consist of a body, a nut, and an olive (ferrule), which compresses onto the pipe or tube when tightened. These fittings create a tight and secure seal, preventing leaks and ensuring efficient fluid or gas flow. Brass compression fittings are particularly popular due to their excellent strength, ease of installation, and versatility across different industries.

 

Benefits of Brass Compression Tees and Compression Fittings

Brass Compression Fittings are mechanical devices used to join pipes or tubes by compressing a ring or ferrule between a nut and a fitting body. The compression creates a secure seal that prevents leaks while allowing for future disassembly if needed.

 
Key Benefits:
  • No soldering required
  • Easy installation and maintenance
  • Reusable in many cases
  • Suitable for various pipe materials

 

Types of Brass Compression Fittings

  • Equal Tee: All three connections are the same size
  • Reducing Tee: Branch connection is smaller than the run
  • Service Tee: Specifically designed for water service lines
  • Stop Tee: Includes an integrated shut-off valve

 

Threads

Thread TypeDescriptionCommon Applications
