Bridgeport Fittings Mighty-Bond® Raintight Grounding Hub, Stainless Steel

The Bridgeport Fittings Mighty-Bond® Raintight Grounding Hub is a raintight grounding and bonding connector built for conduit runs that demand a secure, corrosion-resistant ground path. Available in trade sizes from 1" to 1-1/2", this hub is machined from a stainless steel alloy and sealed with a premium Buna-N O-ring, making it well suited for outdoor, wet-location, and industrial conduit terminations where a dependable, weathertight bonding connection is required for code-compliant grounding. Across the size range, the hub is sized to accept large-gauge copper or aluminum conductors, giving electrical contractors a consistent, reliable grounding solution regardless of the specific conduit size selected.

Bridgeport Fittings MCH-100 – Frequently Asked Questions

1) Can a Mighty-Bond grounding hub be used outdoors in a wet location?
Yes. The Mighty-Bond hub is raintight rated and suitable for wet locations, sealed at the conduit entry with a Buna-N O-ring. That is what makes it usable on outdoor service entrance and feeder terminations rather than an indoor-only bonding bushing.
2) Will this grounding hub take an aluminum ground conductor, or copper only?
Both. The Mighty-Bond hub is rated for copper or aluminum grounding conductors, so it works on aluminum feeder grounds without a separate transition. The exact wire range varies with the trade size you select.
3) Is a stainless steel grounding hub worth it over a standard malleable or zinc fitting?
Where the fitting sits in a corrosive or continuously wet environment, yes. The Mighty-Bond body is a stainless steel alloy, which holds up where plated steel eventually blooms rust and loses contact integrity at the ground path. For a dry indoor pull box, a standard fitting does the same electrical job for less material cost.
4) What conduit types is the Mighty-Bond hub intended for?
Rigid and IMC conduit systems. It lands at the enclosure entry and provides the bonding point for those threaded raceway runs, typically on service entrance and feeder terminations in commercial and industrial work.
5) Does a grounding hub replace the need for a separate bonding bushing at the enclosure?
The Mighty-Bond hub is itself the dedicated grounding and bonding connector at the conduit entry, with a lug for the bonding conductor, so it does the job a bonding bushing plus locknut would otherwise do, and it seals the entry as well. It does not substitute for the grounding electrode or equipment ground conductor sizing required by your inspection.
6) I need to order a Bridgeport grounding hub for 1-1/2 inch rigid, what is the part number?
MCH-150 is the 1-1/2 inch Mighty-Bond stainless raintight grounding hub. The 1 inch version is MCH-100. Those are the only two sizes in the stainless Mighty-Bond hub range.
