The Socket Fusion Coupling (also known as a PPR Equal Coupling or Socket) is the most fundamental fitting used to join two pieces of PPR pipe of the same diameter in a straight line. It is the backbone of any PPR piping extension or repair. Our couplings are injection-molded to precise tolerances, ensuring a perfect interference fit with the pipe during the heating process. This results in a homogeneous, permanent joint that is stronger than the pipe itself, making it the most reliable method for extending pipeline runs.
Socket Fusion Couplings
Key Advantages
Permanent Joint: Once fused, the coupling and pipe become a single piece, eliminating the possibility of future leaks at the joint.
High Mechanical Strength: Withstands internal water pressure and external physical stress without cracking or separating.
Cost-Effective: The simplest and most economical way to connect pipes, reducing material costs for contractors.
Fast Installation: A joint can be made in seconds using a standard welding machine, speeding up project timelines.
Versatile Application: Used in concealed wall installations, underground piping, and exposed industrial lines.
FAQ
Q: Can a coupling be used to repair a burst pipe?
A: Yes, by cutting out the damaged section and using two couplings with a short piece of new pipe, a permanent repair can be made quickly.
Q: What is the welding temperature for these couplings?
A: The standard welding temperature for PPR couplings is 260°C (±5°C).
