HDPE Duct Sealing Plug for Telecom & Underground Infrastructure in KSA
The Duct End Plug 20mm is a small but significant part that is made to close the 20mm open ends of the HDPE and micro-duct systems used for telecom, fiber optic, and underground utility installations. The main purpose of the Duct End Plug is to keep the interiors of the ducts clean and operational by preventing the infiltration of dust, sand, water, insects, and other foreign materials that can affect cable performance and installation efficiency.
The Duct End Plug 20mm is made from top-notch, long-lasting polymer material, which allows it to form a strong push-fit seal without requiring any tools or adhesives. It is fit for both short and long-term usages, thereby causing no dirtiness in ducts while facilitating cable pulling or future expansion.
This product is frequently utilized throughout Saudi Arabia and the Gulf region; it is perfectly suitable for severe environmental conditions where protection and reliability are most needed. The Duct End Plug 20mm is a great contributor to the longevity of the duct, lowered maintenance costs, and overall better infrastructure performance in the long term.
The Duct End Plug 20mm is a precision-engineered sealing accessory designed to securely close the open ends of 20mm HDPE ducts, micro ducts, and telecom conduits. It plays a critical role in protecting underground and surface-level duct networks from dust, moisture, sand, insects, rodents, and foreign particles, ensuring long-term system reliability.
Manufactured from high-grade polyethylene or elastomer-based material, the 20mm duct end plug delivers a tight, durable fit without damaging the duct. It is widely used in telecommunication networks, fiber optic installations, FTTH projects, power utilities, and infrastructure developments across Saudi Arabia and the Gulf region, where harsh environmental conditions demand superior sealing solutions.
Compact in size yet essential in function, the Duct End Plug 20mm helps maintain duct cleanliness before, during, and after cable installation—significantly reducing maintenance costs and cable damage risks.

They are extensively used in fiber optic and telecom ducting systems as protection for ducts before and after cable blowing.
Micro-duct sealing is one application where they are critically important as it rules out the chance of contamination that could obstruct fiber installation.
Ducts are sealed so that the space reserved for future power or control cable installations is not affected.
Unutilized ducts are kept sealed during construction works that are done in stages.
It stops the infiltration of sand and chemicals in such a harsh industrial environment.
In areas including Saudi Arabia, the UAE, Qatar, Oman, Bahrain, and Kuwait, the infrastructure systems are subjected to severe challenges which include:
