Coupling

Overview

Ensure the integrity of your electrical wiring with our precision-engineered conduit couplers. Whether you are working on industrial suspended ceilings or heavy-duty concealed infrastructure, our couplings offer the perfect fit to prevent wire slippage and ensure long-term stability.

Core Product Types

JDG Coupler (Set-screw Type): Features integrated set screws that bite into the conduit for maximum grounding efficiency. Designed for rapid installation in commercial ceiling and surface-mounted projects.

KBG Coupler (Indent-crimp Type): Offers a sleek, protrusion-free profile. Secured using a crimping tool, this coupler is ideal for tight spaces and concealed installations where a smooth surface is required.

SC Coupler (Threaded Connector): A heavy-duty, threaded solution for thick-walled steel pipes. Provides superior sealing against water, dust, and explosion risks, making it the top choice for harsh or high-pressure environments.

Key Advantages

Perfect Fit & Precision: Engineered for tight tolerances to match standard conduit sizes (Φ16, Φ20, Φ25, Φ32, etc.), ensuring a secure connection at the internal stopper.

High Mechanical Reliability: Maintains structural strength at junction points, protecting your wiring from physical impact and environmental stress.

Grounding Continuity: Specifically designed to provide excellent electrical pathways, reducing the need for additional complex grounding work (especially with JDG types).

Installation Tips for Professional Results

Match Specifications: Always ensure the nominal diameter of the coupler matches your conduit size exactly.

Correct Insertion Depth: Insert the conduit until it reaches the internal centering ring of the coupler to guarantee a balanced, secure connection.

Deburring: Before insertion, please file the cut ends of your conduits to remove sharp burrs; this protects cable insulation from being scratched during the wiring pull process.

Common Applications

High-end commercial office buildings
