ABB PVC-Coated Zinc Hub Connector, Insulated Throat, Dark Gray

The ABB PVC-Coated Zinc Hub Connector is engineered to positively bond conduit to a box or enclosure in demanding corrosive and wet-location environments. Built with a zinc body, a nominal .002 inch (2 mil) blue urethane interior coating, and a minimum .040 inch (40 mil) PVC coating bonded to the exterior, this hub connector features a thermoplastic insulated throat, a Nitrile Rubber (Buna-N) sealing ring, and a 105 C temperature rating. It is CSA certified and finished in Dark Gray for long-term reliability on rigid conduit installations.

Key Features

  • Pipe Size: 3/4 Inch/21 Metric connection for standard rigid conduit hub applications.
  • Dual-Layer Corrosion Protection: Zinc body with a nominal .002 inch (2 mil) blue urethane interior coating applied before a minimum .040 inch (40 mil) PVC coating is bonded to the exterior.
  • Insulated Throat: Thermoplastic insulated throat with sharper, deeper teeth to protect conductors while positively bonding conduit to the box or enclosure.
  • Hexagonal/Splined Body and Locknut: Enables fast and easy installation with a secure mechanical connection.
  • Sealing System: Nitrile Rubber (Buna-N) sealing ring with an innovative sealing ring and groove design, plus pressure sealing sleeves to protect the connection.
  • Dimensions: Overall diameter 1.44 Inch/36.58 Millimeters, throat diameter 0.78 Inch/19.81 Millimeters, and maximum panel thickness 0.19 Inch/4.83 Millimeters.

Ocal HUB3/4-G – Frequently Asked Questions

1) Will the ABB PVC-coated hub connector fit 3/4 inch rigid conduit?
Yes. The ABB PVC-coated zinc hub connector is a 3/4 inch / 21 metric trade size fitting for standard rigid conduit hub applications. Two ordering codes cover it: HUB3/4-G listed at 3/4 inches and HUB1-G listed at 27 millimeters.
2) What panel or enclosure wall thickness can this ABB hub connector be mounted through?
Maximum panel thickness is 0.19 inch (4.83 mm). The fitting's overall diameter is 1.44 inch (36.58 mm) and the throat diameter is 0.78 inch (19.81 mm), so the knockout and surrounding flat area need to clear that body diameter for the sealing ring to seat properly.
3) Is this hub connector suitable for a wet or corrosive location like a wastewater plant?
That is what it is built for. The zinc body carries a nominal .002 inch (2 mil) blue urethane interior coating with a minimum .040 inch (40 mil) PVC coating bonded to the exterior, and the connection is sealed with a Nitrile Rubber (Buna-N) sealing ring plus pressure sealing sleeves. Typical uses called out include industrial and wastewater treatment facilities, outdoor and underground conduit runs, and corrosive wet-location conduit.
4) Does this hub connector bond the conduit to the enclosure, or do I still need a bonding jumper?
The fitting is made to positively bond conduit to the box or enclosure. Its thermoplastic insulated throat uses sharper, deeper teeth that bite while protecting conductors, and the hexagonal/splined body and locknut give a secure mechanical connection. Panelboard and enclosure grounding connections are one of its listed applications. Whether a supplemental bonding jumper is required is still your inspector's call under the governing code for the installation.
5) Is the ABB PVC-coated hub connector certified for Canadian jobs?
It is CSA certified. That is the only certification carried on the fitting's record, so if a spec calls for a specific UL listing number, confirm against the manufacturer's documentation for the project submittal.
6) Will this ABB connector hold up in a high-temperature equipment room?
It is rated for continuous use at 105 C. Between that rating and the PVC over urethane over zinc build, it is aimed at industrial installs rather than ordinary dry indoor work where a plain steel connector would do.
7) Do I need special tools to install this PVC-coated hub fitting?
No. The body and locknut are hexagonal/splined, so standard wrenches or a strap wrench work and installation goes quickly. Take the usual care with PVC-coated fittings not to score the exterior coating with toothed jaws, since that .040 inch PVC layer is the corrosion barrier.
8) What color is this fitting, and will it match existing PVC-coated conduit runs?
The finish is a Dark Gray PVC coating, the standard appearance for PVC-coated rigid conduit systems, so it blends with existing coated raceway rather than standing out.
