Coupling HDPE – Thread Type 20MM
Reliable Pipe Connection Solution for Telecom, Electrical & Utility Networks in KSA & GCC
Why Thread-Type HDPE Couplings Are Preferred in GCC Projects
In the Middle East the infrastructure conditions require fittings that are not only robust but also flexible and dependable. Among other advantages, the 20MM HDPE threaded coupling provides the following benefits over traditional joining methods:
• No heat fusion or welding
• Fast installation using only basic tools
• Simple removal and reinstallation
• Great sealing when thread seal tape or O-ring is used
• Applicable to tight spots and retrofit projects
The aforementioned considerations have resulted in the widespread use of threaded HDPE couplings in urban development, data centers, telecom upgrades, irrigation maintenance, and electrical installations.

Material Engineering: Why HDPE is Used
High-density polyethylene is the most suitable material for textured coupling due to its unparalleled properties that combine the following:
Strength with Flexibility
HDPE gives very high tensile strength but still is flexible enough to prevent cracking or breaking by absorbing ground movement and vibration.
Non-Corrosive Nature
Metal couplings get corroded or rusted with time but HDPE does not even in saline soils that are common in coastal GCC areas.
Thermal Stability
HDPE does not crack or lose its physical properties even at extremely high Gulf temperatures.
Chemical Compatibility
Perfect for industrial zones, irrigation networks, and utility corridors that are prone to chemical exposure.
Lightweight Design
Lessens the time for handling, cost of transportation and labor for installation.
Design Features of the Thread Type 20MM HDPE Coupling
Precision-Molded Threads
Guarantee smooth and strong engagement, as well as minimized risk of cross-threading.
Leak-Resistant Connection
A properly tightened threaded joint provides a secure seal that is perfect for conduits and pipelines.
Compact Profile
Makes it possible to install in tight spaces such as wall chases, trenches, handholes, and cabinets.
Reusability
After several installation cycles, the threads stay in good condition.

• Residential and commercial buildings
• Service shafts
• Utility rooms
Industrial Installations
Used in factories, warehouses, and processing plants for cable protection and fluid transfer lines.
How to Use Coupling HDPE – Thread Type 20MM
Installation Procedure
- First of all, it should be ensured that the HDPE pipe ends have been cleaned up and properly cut.
- Secondly, it should be confirmed that the threads are compatible and the alignment is correct.
- If needed, apply thread seal tape or approved sealant.
- Connect the pipe ends to the coupling by hand.
- Then gently tighten with the appropriate tool, but be very careful not to apply torque more than the recommended.
- Proper alignment and fit should be checked.
Disassembly
Threaded couplings can be unscrewed with ease for modification or repair of the system.
Advantages Over Other Coupling Types
Thread Type vs. Push-Fit
Threaded couplings provide stronger mechanical locking and are less likely to loosen over time.
Thread Type vs. Heat Fusion
No specialized welding equipment required, reducing installation cost and time.
Thread Type vs. Metal Couplings
HDPE couplings do not corrode, are lighter, and are more cost-effective.
