FCST-4HC-SC series is the 3rd generation product developed by FCST for HDPE ducts. The product has passed the air tightness leak test at 250 psi, featuring outstanding corrosion resistance and tolerance to most chemical media. Developed to meet the practical requirements of leading cable duct manufacturers, large utility companies and professional contractors, it is perfectly compatible with both cable jetting and pulling installation methods.
Its compact profile effectively addresses pain points in manholes, narrow trenches and trenching equipment operations. Adopting a convenient push-fit connection structure, it allows easy and efficient installation and removal. Simply push the end of the duct into the coupler to form a locked, airtight joint without any special tools.
Insert the HDPE duct directly into the coupler to create a locked connection. No special tools are required, helping simplify field installation.
The FCST-2ERS is specified for both cable pulling and cable jetting applications, making it suitable for different underground cable installation methods.
The same coupler size can accommodate different HDPE pipe series when they have the same nominal OD and fall within the specified OD working range.
A pre-lubricated EPDM O-ring provides watertight and airtight sealing. The product has passed an air-tightness leak test at 250 PSI.
The self-locking ring secures the duct connection while allowing the coupler to be re-entered when access is required.
The clear midsection allows installers to see the duct position during assembly, reducing guesswork during installation.
The coupler uses an ABS body and components with an EPDM O-ring. Its non-metallic construction provides corrosion resistance and dielectric properties for buried or encased applications.

The FCST-4HC-SC series is available for 1.00", 1.25", 1.50" and 2.00" nominal duct sizes. Each size has a specified OD working range.
Yes, when the pipe series have the same nominal OD and their actual OD falls within the coupler's specified working range.
For example, the referenced 1" HDPE data shows SDR 11, SDR 13.5, Schedule 40 and Schedule 80 with a nominal OD of 1.315". The corresponding FCST-4HC-SC 1" coupler has a 1.305"–1.325" OD working range.
Yes. The product is specified for both cable pulling and cable jetting applications.
No. The push-fit design allows the duct to be inserted directly into the coupler without special tools.
A pre-lubricated EPDM O-ring provides watertight and airtight sealing. The product has passed an air-tightness leak test at 250 PSI.
The specification sheet describes the non-metallic construction as suitable for buried or encased applications, with corrosion resistance and dielectric properties.
