Thomas & Betts 680-TB – Frequently Asked Questions

1) What is an Erickson coupling used for on a rigid conduit run?
An Erickson coupling, also called a union coupling, joins two lengths of threaded rigid conduit when neither run can be rotated. Standard threaded couplings require you to spin one pipe into the fitting, which is impossible once both ends are fixed in place. The Thomas & Betts 680-TB is the 2 inch version, made of malleable iron, so it is the fitting you reach for on a repair, a tie-in, or any run boxed in at both ends.
2) Do I need a standard coupling or an Erickson coupling for my conduit splice?
Use a standard threaded coupling when one of the two conduit ends is still free to turn, which is typical on new work as you build the run. Use the 680-TB Erickson type when both ends are already secured, for example cutting into an existing 2 inch run or tying two fixed sections together. The Erickson threads onto both conduit ends and draws them together without either pipe rotating.
3) Is the 680-TB coupling strong enough for industrial conduit work?
It is malleable iron rather than die cast, which is what you want where the conduit takes mechanical abuse or the fitting gets torqued hard during assembly. Thomas & Betts lists it for commercial, industrial, and new construction conduit systems as well as MRO repairs.
4) Do the conduit ends need to be threaded to use this coupling?
Yes. The 680-TB is a threaded fitting, so both 2 inch conduit ends must be cut, reamed, and field threaded before assembly. If your run is EMT rather than threaded rigid or IMC, this is the wrong fitting; EMT takes set screw or compression couplings instead.
5) What part number should I order for the 2 inch Thomas & Betts Erickson coupling?
Order Thomas & Betts 680-TB. That is the manufacturer part number for the 2 inch malleable iron Erickson coupling, and it is the only configuration in this size.
