EMT Compression Coupling · 3 in Trade Size · Die-Cast Zinc, Concrete-Tight/Raintight · Bridgeport Fittings 267-DC
SKU: CKZ300
Compression coupling for joining two lengths of 3 in EMT conduit in commercial and industrial runs. Die-cast zinc construction with concrete-tight and raintight performance; commonly selected where a more secure EMT connection is needed than set-screw style fittings.
What this product is for
This 3 in EMT compression coupling is used to join two lengths of electrical metallic tubing in exposed or concealed raceway systems. It is intended for trade installations that require a secure mechanical connection with concrete-tight performance and raintight suitability.
Use for
Use for 3 in EMT conduit runs in commercial, industrial, and institutional installations. Suitable where electricians want a compression-style fitting in indoor or outdoor locations and where concrete-tight EMT fittings are specified.
Avoid for
Avoid using this fitting where the raceway system calls for a coupling specifically listed for rigid conduit only, or where conduit type and listing do not match the installation. Always confirm compatibility with the conduit material and local electrical code requirements before installation.
Best for
Best for larger trade-size EMT runs where connection security, weather resistance, and a listed compression fitting matter. Also useful on projects where steel or aluminium EMT is being installed and a concrete-tight connection is required.
Installed in
Typically installed in service rooms, plant areas, commercial buildings, schools, retail spaces, and outdoor raceway runs using 3 in EMT. Trade size is 3 in (78 mm nominal).
Why this product exists
Compression couplings are used to connect EMT sections while helping maintain mechanical continuity and a tighter connection than basic set-screw styles in many applications. For larger conduit runs, this style is commonly chosen where installers want a more secure fit for demanding environments.
Compared with similar products
Compared with set-screw EMT couplings, a compression coupling is typically chosen for concrete-tight applications and where raintight performance is required by the fitting listing. Compared with steel compression couplings, this model uses die-cast zinc construction. Actual suitability depends on the conduit type, environment, and local code.
Specifications
