The 3N1® Boreable Conduit is a specialized HDPE solution designed to streamline the installation of multiple ducts in a single pull. By factory-bundling three individual conduits under a protective, low-friction oversheath, 3N1® eliminates the "bird-nesting" and spiraling that often occurs when pulling loose ducts during Horizontal Directional Drilling (HDD).
Traditional multi-duct pulls involve high risks of tangling, which can prevent successful cable blowing or pulling later. 3N1® solves these field challenges before they happen.
- Anti-Spiraling Design: The unique configuration ensures that the conduits remain in a fixed, parallel position throughout the entire bore, maintaining the integrity of each pathway.
- Reduced Pulling Tension: The specialized outer jacket is designed to glide through the bore hole with significantly less resistance than three loose pipes, reducing stress on your drilling equipment.
- Maximized Bore Space: By maintaining a tight, consistent profile, 3N1® allows for smaller bore holes, saving time, fuel, and drilling fluid.
Color-Coded Identification: Each internal duct is color-coded, making it easy for field crews to identify and assign specific fiber or power lines at both ends of the run.
3N1® is the preferred choice for high-stakes infrastructure projects where precision and speed are non-negotiable:
- Urban Fiber Expansion: Navigating crowded underground utility right-of-ways with multiple pathways.
- Highway & River Crossings: Ensuring 100% success on long-distance, high-cost bores.
- Broadband & 5G Backhaul: Rapidly deploying triple-pathways for future-proof network scalability.
- Campus & Municipal Networks: Providing dedicated ducts for data, security, and power in a single installation pass.
To connect longer runs of 3N1™, Blue Diamond and ETCO Specialty Products have developed a coupling system that pressure-seals the innerducts and provides a positive water-tight connection for the outer casing pipe. The innerducts are connected using a 6" wide, dense polyurethane elastomer ribbed internal compression fitting. The fitting can withstand 100 psi pressure, making it ideal for blowing fiber through the innerducts. The 3N1 casing connector is a 12" long rigid PVC case with a ribbed polyurethane insert. It opens as a clamshell to easily accomodate the HDPE casing in the field. Five marine grade stainless steel clamps compress the polyurethane liner making the entire connection water-tight. Stainless steel screws and clamps provide up to a 1000lb tensile pull strength for pull apart in a plow or trench application. However, use of a coupler in a HDD boring application is still not recommended.
