Stainless Steel LT 90° Connector UL 514B

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

TSI INOX Conduits presents our premium Stainless Steel LT 90° Connector, a high-performance right-angle fitting engineered to secure, ground, and seal Liquid-Tight Flexible Metal Conduit (LTFM) to boxes, enclosures, and equipment in tight, space-constrained installations. Manufactured from premium SS316 stainless steel with a vibration polished finish, our 90° LT connectors provide reliable, corrosion-resistant connections where superior corrosion resistance and/or strength is required.

Stainless Steel LT 90° Connector - UL 514B

The LT (Liquid-Tight) 90° Connector is specifically designed to terminate liquid-tight flexible metal conduit in wet and dry locations at a right angle, ideal for routing conduit around obstacles and in confined spaces where straight connections are impractical. Built for long, dependable service in tough industrial and standard applications, our SS316 LT 90° 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 90° connectors deliver the quality, durability, and code compliance your project demands.

Key Features

90° Right-Angle Design

The 90° connector configuration provides critical installation advantages:

  • Space-constrained routing – Ideal for tight spaces where straight connectors cannot be used
  • Obstacle avoidance – Routes conduit around equipment and structural obstacles
  • Professional installation – Provides clean, neat conduit runs in complex layouts

Superior Corrosion Resistance

Manufactured from Type 316 stainless steel, our LT 90° 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 90° 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

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 90° connector is supplied complete with:

  • Stainless steel locknut – For secure mounting to boxes and enclosures
  • Sealing gasket – Provides raintight sealing against the enclosure wall
  • Gland nut sealing ring – Creates a liquid-tight seal around the conduit jacket

Grounding Capability

  • UL listed for grounding – Suitable for trade sizes ½" through 1¼" under NEC
  • Reliable ground continuity – Maintains equipment grounding path through the connector

Hazardous Location Suitability

UL listed liquid-tight flexible metal conduit fittings are suitable for use in the following hazardous locations under NEC :

  • Class I, Division 2 – Groups A, B, C, D
  • Class II, Division 1 & 2 – Groups E, F, G
  • Class III, Division 1 & 2
