ABB ST12 Series PVC-Coated Liquidtight Steel Conduit Connector

The ABB ST12 Series PVC-Coated Liquidtight Conduit Connector is a steel fitting engineered to positively bond liquidtight conduit to a box or enclosure in demanding, corrosive, and hazardous-location environments. Each connector carries a minimum .040 inch (40 mil) PVC coating bonded to the exterior over a nominal .002 inch (2 mil) blue urethane coating applied to both the interior and exterior surfaces before the PVC coating is applied. Finished in dark gray, the ST12 Series is UL Listed and CSA compliant for dependable, code-ready installations, and is available in straight, 45 degree, and 90 degree configurations to suit varied routing needs.

Key Features

  • Durable Construction: Steel fitting body provides a rugged, dependable base for liquidtight conduit connections.
  • PVC Coating: A minimum of .040 inch (40 mil) PVC coating is bonded to the exterior for enhanced corrosion resistance.
  • Double Urethane Base Coat: A nominal .002 inch (2 mil) blue urethane coating is applied to both the interior and exterior before the PVC coating, adding a protective layer beneath the exterior finish.
  • Configuration Options: Available in straight, 45 degree, and 90 degree configurations to suit varied routing needs.
  • Positive Bonding: Designed to positively bond conduit to a box or enclosure for a secure electrical connection.
  • Pressure-Sealing Sleeves: Pressure-sealing sleeves are engineered to protect the connection point.

Ocal ST1/2-G – Frequently Asked Questions

1) What is the PVC coating thickness on the ABB ST12 Series liquidtight connector, and what is under it?
The ST12 Series connector has a minimum .040 inch (40 mil) PVC coating bonded to the exterior of the steel body. Underneath that, a nominal .002 inch (2 mil) blue urethane coating is applied to both the interior and exterior surfaces before the PVC goes on, so the inside of the fitting is protected too, not just the outside. That interior coating matters in corrosive service where vapor can reach the bore.
2) Is the ABB ST12 connector approved for hazardous location work?
Yes. The ST12 Series is UL Listed, CSA certified, and rated for hazardous locations. That combination is what typically gets it past an inspector on corrosive or classified-area raceway, and it is the reason the PVC-coated steel body is specified rather than a plain zinc die cast fitting.
3) Does the ABB ST12 liquidtight connector bond the conduit, or do I still need a separate bonding jumper?
The ST12 is built to positively bond liquidtight conduit to the box or enclosure, so the fitting itself carries the bond through the steel body. Whether an external bonding jumper is still required comes down to the circuit and the installation rules the job is inspected under, but the connector is not a plastic fitting that breaks continuity.
4) Will the ABB ST12 connector keep water out of my enclosure in a washdown or outdoor area?
The ST12 uses pressure-sealing sleeves engineered to protect the connection point where the liquidtight conduit enters the fitting, and the PVC-coated steel construction is intended for wet and corrosive environments. It is a liquidtight fitting, so it must be used with liquidtight flexible conduit, not standard flex.
5) What are the exact part numbers for the ABB ST12 series connectors?
Three part numbers cover the series: ST1/2-G for the straight connector, ST1/245-G for the 45 degree, and ST1/290-G for the 90 degree. All are PVC-coated steel liquidtight connectors in the ST12 family.
6) Why use a PVC-coated steel liquidtight connector instead of a standard uncoated one?
Coating is the whole point of the ST12. A standard fitting is fine in dry interior work, but in corrosive, wet, or hazardous-location service the exposed metal is what fails first. The ST12 puts 40 mil of PVC over the steel exterior plus a 2 mil urethane layer inside and out, so both the visible body and the bore are protected. If the environment is benign, the coated fitting is more than the job needs.
7) What color are ABB ST12 PVC-coated fittings, and will they match other PVC-coated conduit on the job?
The ST12 Series finishes in dark gray, which is the usual look for PVC-coated conduit systems, so it reads consistently alongside other coated raceway on a plant or facility run. For a property or facilities team standardizing on one fitting across coated conduit, all three angles share the same coating spec and finish.
