Thomas & Betts ST145-G OCAL PVC-Coated Liquidtight Flexible Conduit Connector

The Thomas & Betts ST145-G is a PVC-coated liquidtight conduit connector from the OCAL series, engineered to terminate liquidtight flexible conduit (LFMC) at boxes, panels, and equipment enclosures throughout commercial and industrial electrical systems. Its PVC-coated body adds a protective layer against moisture, chemicals, and corrosive atmospheres that can degrade uncoated metal fittings over time, while the liquidtight connection design helps keep conductors sealed and protected as flexible conduit transitions into an enclosure. Suitable for new installations and retrofit projects alike, the ST145-G helps maintain a corrosion-resistant conduit pathway for sensitive electrical connections, backed by the Thomas & Betts name that contractors rely on for dependable conduit hardware on demanding job sites.

Key Features

  • OCAL Series: The ST145-G is part of the Thomas & Betts OCAL line of PVC-coated conduit fittings, a series widely specified for corrosion-prone electrical applications.
  • PVC-Coated Construction: A PVC coating covers the connector body, adding resistance to moisture, chemical exposure, and general corrosion compared to uncoated fittings.
  • Liquidtight Design: Engineered to terminate liquidtight flexible conduit (LFMC) at boxes and enclosures, helping keep moisture and contaminants out at the connection point.
  • Conduit Connector Function: Provides a secure mechanical termination point for conduit runs, supporting organized and code-conscious conduit routing.
  • Model ST145-G: Identified under the Thomas & Betts part number ST145-G for straightforward specification and ordering.
  • Thomas & Betts Reliability: Manufactured under the Thomas & Betts brand, a name long relied upon for conduit and fitting hardware in professional electrical work.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Liquidtight Flexible Conduit (LFMC) Terminations
  • Corrosive and Chemical-Exposure Electrical Environments
  • Wet and Damp Location Conduit Routing
  • Commercial and Industrial Electrical Installations
  • Outdoor and Exposed Conduit Runs

Why Thomas & Betts?

Ocal ST145-G – Frequently Asked Questions

1) What is the Ocal ST145-G connector used for?
The Ocal ST145-G is a PVC-coated liquidtight connector that terminates liquidtight flexible metal conduit (LFMC) at boxes, panels, and equipment enclosures. The liquidtight connection seals the transition point so moisture and contaminants stay out of the enclosure where the flex lands.
2) Is the ST145-G steel or nonmetallic, and what does the PVC coating actually do?
The body is steel with a PVC coating over it, finished in dark gray. The coating is what buys you the corrosion resistance: it shields the steel from moisture, chemical exposure, and corrosive atmospheres that eat uncoated metal fittings. If you want a metal fitting in a wash-down bay, water treatment plant, or chemical process area, that is the reason to pick this over a plain zinc or steel connector.
3) What is the difference between the Ocal ST145-G connector and the Hubbell SwivelLok PS0509N?
Both terminate liquidtight flexible conduit, but they are built for different environments. The Ocal ST145-G is a steel-bodied connector with a PVC-coated finish, intended for corrosive, chemical-exposure, and wet-location conduit runs where an uncoated metal fitting would degrade. The Hubbell PS0509N is a nylon SwivelLok connector in 1/2 inch, and its multi-position swivel body lets the conduit leave the enclosure at an angle rather than straight out. Choose the ST145-G when corrosion protection on a metal fitting is the requirement, and the SwivelLok when the run needs angular flexibility at the box.
4) Is the SEPCO UF10 connector a substitute for the Ocal ST145-G?
No. The SEPCO UF10 series is a die-cast zinc connector for underground feeder (UF) cable, so it terminates a jacketed cable rather than conduit. The Ocal ST145-G is a liquidtight connector that terminates liquidtight flexible conduit (LFMC) into boxes, panels, and enclosures. They look similar in a bin but serve different wiring methods, and the UF10 cannot clamp flexible conduit.
5) Can I use a PVC-coated liquidtight connector outdoors and in wet locations?
Yes. Wet and damp location conduit routing, outdoor and exposed runs, and corrosive or chemical-exposure environments are the stated applications for the ST145-G. That combination of a liquidtight seal plus PVC over steel is specifically what the OCAL line is specified for.
6) How do I order the right part, and what part number do I give my distributor?
Order it as ST145-G. That is the manufacturer part number as well as the only model configuration offered, so there is no size or finish option to specify separately.
7) Can I use a nylon liquidtight connector instead of the PVC-coated Ocal ST145-G?
A nylon connector such as the Hubbell SwivelLok PS0509N is a liquidtight termination and is a reasonable choice where the concern is simply sealing a conduit entry. The Ocal ST145-G differs in that it is a steel connector carrying a PVC coating, which is the construction typically specified when the atmosphere is corrosive or chemically aggressive and a metallic fitting is still wanted in the pathway. If your drawing calls out PVC-coated metallic fittings for the run, a nylon body is not an equivalent; if it does not, the nylon connector is a simpler option.
8) We run both LFMC and UF cable on the same outdoor job. Do I need two different connectors?
Yes, each wiring method takes its own fitting. The Ocal ST145-G handles the liquidtight flexible conduit terminations and carries a PVC-coated steel body for corrosive and wet-location exposure. For the UF cable runs, the SEPCO UF10 series die-cast zinc connector is the fitting matched to underground feeder cable. Ordering one type for both will leave part of the job without a usable termination.
9) Can I use the Ocal ST145-G on a retrofit, or is it only for new construction?
Both. The ST145-G is suited to new installations and retrofit work alike, which matters when you are replacing corroded uncoated fittings on an existing metal conduit pathway and want the rest of the run to keep its corrosion protection.
