Technical Application

The Topaz 19003 Liquid Tight Connector provides a right-angle termination for flexible non-metallic liquid-tight conduit in wiring systems where directional changes and compact routing are required. The nylon body resists corrosion, chemicals, and UV exposure, ensuring long-term service life in demanding industrial or outdoor environments. The connector’s compression-style fitting ensures a secure mechanical connection while preserving liquid-tight integrity. The non-metallic construction provides dielectric isolation, making it suitable for non-conductive conduit systems or installations requiring reduced EMI interference. The 90° configuration allows for efficient routing of conduit in tight or confined spaces while maintaining strain relief on the conduit body.
