Connector for corrugated electrical conduit Onnline ZCL-18S, grey, 18 mm, 300 pcs

Onnline ZCL-18S is a pack of 300 grey connectors designed for use with 18 mm corrugated electrical conduit. These connectors provide a consistent mechanical connection between sections of flexible conduit, helping to maintain an enclosed routing for electrical cables and preserving the continuity of protective conduit runs in indoor wiring installations. The neutral grey finish suits a range of installation environments including walls, ceilings and junction enclosures.

Advantages

The connectors are supplied in a bulk quantity of 300 pieces to support larger installations or stock for repeat jobs. Each fitting is sized for 18 mm corrugated conduit, offering a secure press-fit connection that reduces the risk of conduit separation and helps maintain cable protection. The grey material is durable and suitable for typical indoor conditions, providing consistent fit and repeatability across many joints.

How to use

Prepare conduit ends by ensuring they are clean and cut square. Insert the conduit ends into each connector until a secure fit is achieved; verify that the corrugations engage and the joint is stable. Use the connectors to join two conduit sections or to continue runs through junction points. After assembly, check that cables can pass freely and that the conduit line maintains continuous protection along its length.

Usage recommendations

Store connectors in a dry, dust-free area before use. For installations subject to mechanical stress or movement, verify that the connection method and conduit support meet applicable electrical installation standards and local regulations. Do not use these connectors for outdoor or direct-burial applications unless confirmed suitable by local code and material specifications.
