※ Product launch related to pipe fittings:1. Nipple: Used to connect two fittings and is most commonly used in plumbing solutions.
2. Reducer: If you want to connect two pipes with different widths, use a reducer in this case.
3. Angle: This changes the direction of the pipe by 45 ° or 90 °.
4. Cross: As the name suggests, this component has a cross shape with four branches in opposite directions. One of the four crosses serves as an entrance, while the remaining three branches serve as an exit.
5. Connection: The pipeline must be disconnected during maintenance, fastening or replacement.
