INOX Conduits presents our premium Stainless Steel LT Combination Coupling, a high-performance hybrid fitting engineered to bridge the gap between Liquid-Tight Flexible Metal Conduit (LTFM) and Rigid/IMC conduit systems. Manufactured from premium SS316 stainless steel with a vibration polished finish, our combination couplings provide reliable, corrosion-resistant connections for transitioning between different conduit types in demanding installations.
The LT Combination Coupling is specifically designed with a liquid-tight connector on one end for terminating flexible conduit and a rigid coupling on the other for connecting to rigid metal conduit or IMC . This versatile solution eliminates the need for multiple fittings when transitioning between flexible and rigid raceway systems, providing a single, labor-saving connection point. Whether you are connecting equipment with vibration isolation requirements, making transitions in corrosive environments, or completing installations in food processing facilities, chemical plants, or marine environments, TSI's stainless steel LT combination couplings deliver the quality, durability, and code compliance your project demands .
The LT combination coupling provides critical installation advantages by combining two essential functions into one compact fitting :
Manufactured from Type 316 stainless steel, our combination couplings provide long, dependable service where superior corrosion resistance is required . The 316 alloy provides:
Our combination couplings feature premium surface finishes:
When properly installed, the combination coupling provides :
Each LT combination coupling is supplied complete with:
UL listed liquid-tight flexible metal conduit fittings are suitable for use in the following hazardous locations under NEC :
