Where the CP25 Fits in Electrical Conduit Installations

A conduit coupling is one of the most frequently used fittings in any conduit wiring installation — wherever two separate lengths of conduit need to be joined in a straight run, a coupling is the fitting that makes the connection. The CP25 joins two 25mm conduit lengths end to end, maintaining a consistent internal bore of 25.2mm for unobstructed cable pulling through the conduit run. The grey PVC construction is UV stable and compatible with standard PVC conduit adhesive for a permanent, secure join.

The 25mm conduit size is widely used across Australian residential, commercial, and industrial wiring installations — it is the common step up from 20mm conduit where larger cable bundles or higher cable counts are required in the run. Typical applications include surface-mounted conduit runs on external walls, concealed conduit in concrete slabs and brick walls, underground conduit runs, and conduit through wall and ceiling cavities where the cable load exceeds 20mm conduit capacity.

The CP25 is the 25mm variant in the Transco conduit coupling range. The same coupling is available in 20mm (CP20), 32mm (CP32), 40mm (CP40), and 50mm (CP50) to cover the full range of standard Australian electrical conduit sizes. Sold individually — specify the quantity needed for the installation based on the number of conduit joins required in the run.

Q: What conduit does the Transco CP25 coupling suit?
A: The CP25 suits standard 25mm PVC electrical conduit with an inner diameter of 25.2mm. It joins two lengths of 25mm conduit end to end in a straight run and is compatible with standard PVC conduit adhesive for a permanent join.

Q: What is the difference between the CP20 and CP25 conduit couplings?
A: The CP20 suits 20mm conduit (inner diameter 20.1mm) and the CP25 suits 25mm conduit (inner diameter 25.2mm). Both are grey PVC push-fit couplings in the same Transco range. Choose the size that matches the conduit installed in the run.

Q: Is the Transco CP25 suitable for outdoor and underground conduit installations?
A: Yes. The CP25 grey PVC construction is suitable for surface-mounted outdoor conduit runs, underground conduit installations, and concealed conduit in walls and slabs where 25mm conduit is specified. Confirm compatibility with the conduit adhesive being used for the installation.
