American Fittings STRNT100 – Frequently Asked Questions

1) What does the American Fittings STRNT combo coupling actually connect?
The STRNT is a one-piece combo body that takes liquidtight flexible metal conduit on one end and rigid steel conduit on the other. You don't need a separate LT connector plus a rigid coupling to make the transition, it's handled in a single fitting. Typical use is where a rigid run drops to a whip of liquidtight going into a motor, pump, or rooftop unit.
2) What trade sizes does the STRNT LT combo coupling come in?
Five trade sizes: 3/4 inch, 1 inch, 1-1/4 inch, 1-1/2 inch and 2 inch. The part numbers run STRNT 75, STRNT100, STRNT125, STRNT150 and STRNT200. Both ends of the fitting are the same trade size, so it's a straight same-size transition rather than a reducer. If you need to change size at the same point, make the transition first and reduce separately.
3) Will the STRNT coupling pass on a federally funded job that requires Buy American?
Yes. The STRNT combo couplings are made in the United States and Buy American Act compliant across the full size range, and they're flagged ARRA compliant, which is what most federal and federally-assisted construction specs are checking for. Country of origin on record is the United States.
4) Is the American Fittings STRNT coupling UL listed for grounding and bonding?
It carries cUL Listing to both UL 514B and UL 467. UL 514B is the conduit fitting standard and UL 467 covers grounding and bonding equipment, so the fitting is recognized as part of the equipment grounding path, not just a mechanical connection. It also meets NEMA FB 1 and Federal Specification A-A-50553.
5) Can I use this combo coupling to transition liquidtight into EMT instead of rigid?
The STRNT is built for rigid steel conduit on the rigid end, and it's spec'd to Federal Spec A-A-50553 for rigid conduit fittings. If your run is EMT, you want an EMT-to-liquidtight combination fitting instead. Using a rigid-threaded end on EMT isn't a thread match.
6) How do I order the right STRNT part number for my conduit size?
Match the number in the part code to the trade size in hundredths of an inch: STRNT 75 for 3/4 inch, STRNT100 for 1 inch, STRNT125 for 1-1/4 inch, STRNT150 for 1-1/2 inch, STRNT200 for 2 inch. Trade size is the only option to specify, there is no finish or material choice to make.
7) Does the STRNT coupling meet RoHS and Prop 65 requirements for a facility submittal?
Across the STRNT family the record shows RoHS compliant, REACH compliant, CA Prop 65 compliant, and Conflict of Minerals certified. That covers the usual environmental and materials-disclosure boxes on an institutional or healthcare submittal package.
