HDPE Corrugated Duct Corrugated Coupling
HDPE-Corrugated Duct Corrugated Coupling
Durable 110mm & 90mm HDPE Duct Connection for Telecom, Fiber Optics & Utilities (KSA & GCC)
Why Corrugated Couplings Are Essential
The underground duct networks face many problems, among which are the following:
- The first problem is the water entering the ducts.
- Another big challenge is the soil's movement and pressure.
- Infiltration of sand and dust is also a concern.
- Heavy loading of vehicles on shallow ducts poses a challenge too.
- Finally, cable installation leads to friction.
By opting for a premium quality corrugated duct coupling, one guarantees that the easy of fiber optics, telecommunication and power are kept secure and operative. Couplings counter duct misalignments, preserve the internal bore and reduce maintenance costs by offering a long service life.

Features & Benefits
1. High-Strength Construction
Reinforced polymer or HDPE keeps mechanical strength intact even when soil and vehicles are over it.
2. Waterproof & Dustproof
It keeps sand, dust, and moisture out of the ducts thus securing the sensitive fiber optic and power cables.
3. Smooth Internal Bore
The characteristic provides cable installation with low friction, which is especially when fiber optic networks are concerned.
4. Quick & Easy Installation
Snap-lock or screw-fastened designs make it possible to install the system without the use of heavy tools and ready for use in the field.
5. UV-Proof
You can run ducts in the desert parts of the Gulf where there is a lot of sunlight and they will still be good.
6. Wide Range of Applications
The projects of telecommunications, FTTH, smart city, industrial, and power ducting make it relevant.
7. Long-Term Reliability
The guarantee is that the service will not be interrupted and the maintenance cost will be lower.

Installation Guide
Step 1: Duct Ends Preparation
Use a HDPE duct cutter to make both duct ends straight.
Step 2: Coupling Insertion
Place the duct ends into the coupling and make sure they go in completely.
Step 3: Lock or Secure
Secure the coupling with a snap-lock or screws by tightening it.
Step 4: Inspection of Seals
Check that the EPDM/Rubber seals are correctly placed to prevent water and dust from entering.
Step 5: Cable Installation is Ready
The coupling has a smooth internal bore that allows the installation of fiber optic or electrical cables.
Maintenance & Care
Regular inspection of couplings during routine maintenance
Clean any exposed dirt or sand before tightening
Replace damaged seals or cracked couplings
Avoid exposure to sharp tools or machinery that may damage the coupling
