TSI INOX Conduits presents our premium Stainless Steel Rigid Compression Connector, a high-performance threadless fitting engineered to secure and terminate rigid metal conduit (RMC) and IMC to boxes, enclosures, and other fittings in demanding applications. Manufactured from premium SS316 stainless steel with a vibration polished finish, our compression connectors deliver reliable mechanical connections, superior corrosion resistance, and hygienic cleanability for tough industrial and standard applications .
Unlike threaded connectors, compression connectors grip the full diameter of unthreaded RMC and IMC conduit—they position onto the end of the conduit and feature a gland that tightens with a wrench to lock securely in place . This design eliminates the need for field threading, saving installation time while providing a concrete-tight, weatherproof seal . Whether you are installing in food processing facilities, chemical plants, wastewater treatment facilities, or marine environments, TSI's stainless steel rigid compression connectors deliver the quality, durability, and code compliance your project demands.
TSI rigid compression connectors are designed to:
Manufactured from Type 316 stainless steel to meet stringent sanitary conditions, our compression connectors provide:
