Straight Type, EMT Connector
Straight EMT Connector S52 series is applied on the relay point close to the end of wiring system to switch the EMT to metal flexible conduits for convenient termination and complete wiring protection. The body is made of zinc alloy with RoHS compliance. The fitting is fitted to unthreaded EMT by set screw and connected with metal flexible conduit by a nut. It benefits to apply to indoor or outdoor environments after assembled with the liquid tight metal flexible conduit series PULTG, PCBLTG, PHLTG and PNKLTG.

S52 Series: Set Screw Type EMT to Flexible Metal Conduit Connector
The S52 Series Straight EMT Connector is a high-efficiency transition fitting designed for unthreaded EMT (Electrical Metallic Tubing). It acts as a critical relay point in wiring systems, allowing for a seamless switch from rigid EMT to liquid-tight metal flexible conduits. This ensures convenient termination and provides complete, continuous protection for the entire electrical wiring network.
Key Features of S52 Set Screw Connectors
Effortless Installation (Set Screw Design): Specifically engineered for unthreaded EMT. The integrated set screw provides a secure mechanical grip without the need for pipe threading, significantly reducing field installation time and labor costs.
Robust Zinc Alloy Body: Manufactured from premium zinc alloy with full RoHS compliance, offering high impact resistance and durability for long-term industrial use.
Versatile Environment Application: Once assembled, it is highly effective in both indoor and outdoor environments, providing a reliable barrier against contaminants.
Secure Conduit Termination: The nut-side connection ensures a high-tensile, stable hold on the flexible conduit, maintaining system integrity under vibration.
