Brass Compression Equal Tee is used for connecting together multiple lengths of copper pipe with the same diameter to create a junction. They require no special tools or soldering for installation, just tightened with a spanner. They create a mechanical joint by compressing the ring onto the tube. It is designed for use in hot or cold water systems as well as heating and low pressure gas installations. The joint can be made on wet pipe work and can be dismantled and re-built.
