Thomas & Betts OCAL HUB11/2-G PVC-Coated Zinc Conduit Hub, 1-1/2"

The Thomas & Betts OCAL HUB11/2-G is a 1-1/2" PVC-coated zinc conduit hub engineered to deliver a corrosion-resistant, threaded termination point for rigid and intermediate metal conduit (IMC) entering enclosures, junction boxes, panels, and equipment housings. As part of the OCAL PVC-coated fitting family, this hub pairs a rugged zinc body with a factory-applied PVC coating, giving it far greater resistance to moisture, chemicals, and atmospheric corrosion than an uncoated fitting. The 1-1/2" trade size threaded hub design forms a secure, weathertight seal at the point where conduit enters an enclosure, helping protect the conductors inside from contamination. Electrical contractors and maintenance teams specify OCAL hubs like the HUB11/2-G when a project calls for conduit fittings that can survive years of exposure to washdown, humidity, or aggressive chemical environments without sacrificing the fit and function of a standard threaded hub.

Key Features

  • Trade Size: 1-1/2" hub sized to accept rigid metal conduit or IMC for a precise, code-compliant fit at the enclosure wall.
  • Durable Zinc Construction: A solid zinc body provides the strength and dimensional stability needed for a dependable threaded connection.
  • PVC-Coated Finish: A tough PVC coating is bonded over the zinc base, protecting the hub from corrosion, moisture intrusion, and chemical attack in harsh operating environments.
  • Threaded Hub Design: Creates a secure, weathertight threaded termination point where conduit enters an enclosure, panel, or equipment housing.
  • OCAL Product Line: Part of the Thomas & Betts OCAL PVC-coated series, purpose-built for corrosion-prone industrial, commercial, and outdoor conduit applications.
  • Long Service Life: The combination of a zinc body and PVC coating is designed to outlast standard uncoated conduit hubs in demanding conditions.

Technical Specifications

Typical Applications

  • Corrosion-Prone Industrial Environments
  • Wastewater and Water Treatment Facilities
  • Chemical Processing and Petrochemical Plants
  • Food and Beverage Processing Facilities
  • Outdoor and Coastal Conduit Installations
  • Conduit-to-Enclosure and Equipment Terminations

Why Thomas & Betts?

Thomas & Betts engineered the OCAL line around PVC-coated zinc construction specifically to withstand the corrosive conditions that shorten the service life of standard conduit fittings. The HUB11/2-G pairs a solid zinc hub body with a durable, bonded PVC coating, giving electrical contractors and facility engineers a threaded conduit termination they can rely on for long-term, dependable performance in harsh industrial, chemical, and outdoor settings where corrosion resistance matters most, whether the installation is a wastewater treatment plant, a chemical processing facility, a food and beverage production line, or an outdoor coastal conduit run exposed to salt air and washdown chemicals year after year.

Ocal HUB11/2-G – Frequently Asked Questions

1) What conduit does the Ocal HUB11/2-G hub accept?
The HUB11/2-G is a 1-1/2 inch trade size threaded hub, sized to take rigid metal conduit or IMC at the enclosure wall. The connection is threaded, so it mates with standard 1-1/2 inch threaded rigid or IMC ends, not with EMT compression or set-screw conduit.
2) Is a PVC-coated hub worth it over a plain zinc hub for a washdown or wastewater plant?
That is exactly the case it is built for. The HUB11/2-G is zinc with a factory-bonded PVC coating, which is what gets you through moisture, washdown chemicals, and atmospheric corrosion that eats uncoated fittings. For a dry indoor panel, a standard uncoated hub does the same mechanical job. For wastewater, chemical and petrochemical, food and beverage lines, or coastal outdoor runs, the coating is the reason to spend the money.
3) What is the difference between the Ocal HUB11/2-G conduit hub and the SEPCO TWH series watertight hub?
Both are threaded conduit hubs for terminating conduit at an enclosure wall, but they differ in how they handle the environment and the connection. The Ocal HUB11/2-G is a PVC-coated zinc hub in 1-1/2 inch trade size, with the PVC coating bonded over the zinc body for resistance to moisture, chemicals, and atmospheric corrosion in washdown, chemical, and coastal settings. The SEPCO TWH series is an insulated watertight hub of die-cast zinc construction. If the driver is a corrosive atmosphere - wastewater, petrochemical, salt air - the PVC-coated Ocal hub is the one specified for that duty; if the driver is a watertight entry with an insulated throat on standard interior or exterior steel, the TWH series addresses that.
4) Do I need a PVC-coated hub, or will a plain die-cast zinc watertight hub work?
It depends on what the hub is exposed to. A die-cast zinc watertight hub such as the SEPCO TWH series is built to seal the enclosure entry and insulate the conductor throat. The Ocal HUB11/2-G adds a factory-applied PVC coating bonded over the zinc body, which is what gives it service life in chemical processing, wastewater, food and beverage washdown, and coastal outdoor runs where an uncoated fitting corrodes. For a dry indoor panel entry, the uncoated zinc watertight hub covers the sealing requirement; where the specification calls out a PVC-coated conduit system, the hub needs to match that system, and the HUB11/2-G is the coated fitting for a 1-1/2 inch rigid or IMC termination.
5) Will this hub make a weathertight seal where conduit enters an enclosure?
Yes. The threaded hub design forms a sealed termination at the enclosure, panel, or equipment housing wall, keeping moisture and contamination off the conductors inside. You still need a correctly sized and deburred knockout or drilled opening for the 1-1/2 inch hub, and the enclosure itself has to carry the environmental rating you are after.
6) What is an alternative if I need an insulated watertight hub instead of a PVC-coated one?
The SEPCO TWH Series insulated watertight conduit hub is a die-cast zinc option covering the same conduit-to-enclosure job. The difference is the protection strategy: the Ocal HUB11/2-G relies on a bonded PVC coating over zinc for corrosive and washdown service, while the TWH is a die-cast zinc insulated watertight design. Pick the Ocal where chemical attack and salt air are the problem.
7) Can I use the Ocal HUB11/2-G with uncoated rigid conduit, or does the whole run have to be coated?
Mechanically it threads onto standard 1-1/2 inch rigid or IMC, coated or not. But the point of the PVC coating is an unbroken corrosion barrier. If you terminate into a coated hub from bare conduit, the bare threads at the joint become the weak spot in a corrosive area. In chemical or washdown environments, match coated conduit to the coated hub.
8) Does the SEPCO TWH hub include an insulated throat like the Ocal HUB11/2-G?
The SEPCO TWH series is described as an insulated watertight hub, so the insulated throat is part of that design. The Ocal HUB11/2-G is characterized by its PVC-coated zinc construction and threaded hub body, which forms the weathertight seal where rigid metal conduit or IMC enters an enclosure, panel, or equipment housing. If an insulated throat is a line item on your submittal, the TWH series states it; if the submittal calls for PVC-coated fittings on a 1-1/2 inch run, the HUB11/2-G is the hub written for that.
