PVC duct coupling · 4 in solvent weld · white for Teleduct and DBII/DB2 · Royal SWC04
SKU: SWC04
4 in white PVC solvent-weld duct coupling for joining Teleduct and DBII/DB2 conduit runs. Commonly used on underground duct systems where a straight, solvent-cemented connection is required; verify compatibility with the installed duct type and local code requirements.
What this product is for
This 4 in PVC duct coupling is used to join two lengths of compatible Teleduct or DBII/DB2 conduit in underground raceway installations. It provides a straight solvent-weld connection for electrical duct systems where matching trade size and system type are required.
Use for
Use for 4 in underground duct banks, site servicing, utility raceways, and other buried conduit runs using compatible PVC duct products. It is suited to installations where a white PVC coupling and solvent-weld joint are specified.
Avoid for
Avoid using this coupling on non-compatible conduit systems, on damaged pipe ends, or where a different joining method is specified. Do not assume interchangeability across all PVC piping products without confirming the duct series, fit, and approval requirements.
Best for
Best for electricians and contractors extending or repairing 4 in duct runs where a standard straight coupling is needed. It is a practical choice when maintaining continuity in Teleduct or DBII/DB2 raceway systems.
Installed in
Typically installed in underground electrical infrastructure, commercial site work, utility trenches, and duct bank applications. A 4 in trade size is approximately 102 mm, which is a key matching dimension when selecting fittings.
Why this product exists
This fitting exists to connect two sections of same-size PVC duct with a solvent-welded joint, helping maintain alignment and system continuity through straight runs. For trade planning, proper pipe preparation and solvent cement selection are typically as important as the fitting itself.
Compared with similar products
Compared with bends, adapters, or repair-style couplings, this is a standard straight coupling for joining like-for-like duct sections. Compared with smaller trade sizes, 4 in (102 mm) fittings are commonly selected where larger cable capacity or multi-conductor duct routing is needed, but actual fill and cable pulling performance depend on conductor type, bend count, and installation conditions.
Typical guidance only: conduit fill is governed by code and cable geometry, so always confirm the raceway design before ordering.
