Stainless Steel LT Grounding Straight Connector UL 514B

Premium SS316 Liquid-Tight Flexible Metal Conduit Grounding Connectors for Demanding Applications

TSI INOX Conduits presents our premium Stainless Steel LT Grounding Straight Connector, a high-performance fitting engineered to secure, ground, and seal Liquid-Tight Flexible Metal Conduit (LTFM) to boxes, enclosures, and equipment. Manufactured from premium SS316 (CF8M) stainless steel with a vibration polished finish, our LT grounding connectors provide reliable, corrosion-resistant connections with enhanced grounding capability for tough industrial and standard applications.

Stainless Steel LT Grounding Straight Connector - UL 514B

The LT (Liquid-Tight) Grounding Connector is specifically designed to terminate liquid-tight flexible metal conduit in wet and dry locations while providing a grounding lug and screw for a secure connection for ground wiring . The grounding straight connector provides a robust solution for applications requiring a low-impedance ground path through the flexible conduit system. Built for long, dependable service where superior corrosion resistance and/or strength is required, our SS316 LT grounding connectors meet the most demanding requirements of the electrical industry . Whether you are installing in food processing facilities, chemical plants, wastewater treatment facilities, or marine environments, TSI's stainless steel LT grounding connectors deliver the quality, durability, and code compliance your project demands.

Key Features

Enhanced Grounding Capability

The LT Grounding Straight Connector is specifically designed with a grounding lug and screw that provide a secure connection for ground wiring. This feature ensures:

  • Reliable equipment grounding – Provides a low-impedance ground path
  • Code compliance – Meets NEC requirements for grounding flexible conduit
  • Positive bonding – Ensures continuous ground throughout the raceway system

Superior Corrosion Resistance

Manufactured from Type 316 stainless steel, our LT grounding connectors provide long, dependable service where superior corrosion resistance is required. The 316 alloy provides:

  • Superior corrosion resistance – Exceptional protection against chlorides, acids, and saline atmospheres
  • Molybdenum-enhanced durability – Resists pitting and crevice corrosion in aggressive environments
  • Sanitary properties – Suitable for food processing, pharmaceutical, and hygienic applications
  • Long service life – Eliminates lifecycle costs associated with corrosion-related failures

Vibration Polished Finish

Our LT grounding connectors feature a vibration polished finish that provides:

  • Enhanced corrosion resistance – Smooth surface minimizes crevice corrosion
  • Easy cleaning – Sanitary design suitable for CIP (clean-in-place) systems
  • Professional aesthetic – Uniform, attractive finish
  • Low maintenance – Does not require touch-up or painting

316SS Inside Ferrule

The Type 316 SS inside ferrule provides extra corrosion resistance on the inside of the fitting. Other inside ferrules made of materials such as carbon steel may corrode easily, affecting the entire fitting. The 316SS ferrule ensures:

  • Complete corrosion protection – Inside and out
  • Long-term reliability – Prevents corrosion-related fitting failure
  • System integrity – Maintains performance in aggressive environments

Precision NPT Threading

  • Tapered male hub NPT threads for secure connections to female threaded hubs
  • Leak-resistant joints with excellent ground continuity
  • Sealing gasket provides additional protection against moisture ingress

Long Ferrule Design

The long ferrule provides critical performance benefits:

  • Prevents pullout – Securely grips the liquid-tight conduit to prevent pullout under stress
  • Prevents tight bend "pop-out" – Eliminates conduit disengagement at tight bends
  • Enhanced conduit retention – Provides superior holding power in demanding applications

Insulated Throat

Furnished with an insulated throat (polypropylene) that:

  • Protects wire insulation – Prevents conductor damage during installation and throughout service life
  • Provides smooth entry – Facilitates wire pulling and prevents abrasion
  • Maintains integrity – Provides long-term protection for conductors

Compact, Slim Design

  • Compact, slim diameter – Ideal for space-constrained installations
  • Small turning radius – Facilitates installation in tight spaces
  • Clean, professional appearance – Matches the profile of the conduit

Furnished Components

Each LT grounding connector is supplied complete with:

  • 316SS gland nut – For secure conduit termination
  • Neoprene sealing gasket – Provides raintight sealing against the enclosure wall
  • Polypropylene sealing ring – Creates a liquid-tight seal around the conduit jacket
  • 316SS grounding locknut – For secure mounting and grounding
  • Grounding screw – For secure ground wiring connection

Easy Installation

  • Can be installed using ordinary hand tools
  • Require little maintenance or repair
  • No special tools or equipment required
