Thomas & Betts ELL1SS 1 IN 90 DEG RIGID ELBOW 304SS

Yes. The ELL1SS is a 1 inch 90 degree rigid conduit elbow, threaded on both ends to mate with 1 inch rigid metal conduit and IMC using standard tapered conduit thread. It is part of the rigid and intermediate metal conduit fitting family, so it works in either RMC or IMC runs at that trade size.

That is exactly the case for it. The ELL1SS is 304 stainless steel, so it holds up in food processing washdown bays, coastal and marine-air exposure, water treatment, and chemical areas where hot-dip galvanized rigid fittings eventually rust at the threads. For dry indoor runs a standard galvanized rigid elbow does the same mechanical job for less; the stainless is bought for the corrosion environment.

Mechanically yes, the threads are the same, but be careful about where you do it. Joining 304 stainless to hot-dip galvanized puts two dissimilar metals in contact, and in a wet or salt-air location the zinc will sacrifice at the joint. If the reason you are using the ELL1SS is corrosion, run stainless conduit and stainless couplings through that section rather than making a single stainless elbow the only corrosion-resistant piece.

Order Thomas & Betts ELL1SS. That is the 1 inch, 90 degree, 304 stainless steel rigid conduit elbow, and the SS suffix is what separates it from the galvanized version of the same fitting.

No. The ELL1SS is the elbow only, factory threaded on each end. Budget separately for couplings, locknuts, bushings, or sealing rings the run needs, and in stainless applications order those in stainless too so the corrosion protection is continuous.

Yes, and on 1 inch rigid it is usually the faster call. A factory elbow like the ELL1SS gives a consistent radius without a hickey or a bender, and it keeps the bend count clean for pulling. In stainless especially, field bending is not practical for most crews, so the ELL1SS is the standard way to turn a 90 in a 304 stainless rigid run.
