American Fittings STR-B Zinc Plated Steel Liquidtight Straight Connector

The American Fittings STR-B Liquidtight Straight Connector is engineered to join liquidtight flexible conduit (LFMC) to electrical boxes, enclosures, and equipment housings. Constructed from zinc plated steel with an insulated throat, this connector is built to withstand the rigors of industrial and commercial electrical installations. The STR-B connector is available in trade sizes of 1/2", 3/4", and 1-1/2", giving installers a consistent, reliable connection option across a range of conduit diameters. Its straight body configuration allows for a direct, in-line transition between conduit and enclosure, simplifying routing in tight panel and equipment layouts.

Key Features

  • Trade Size: Available in 1/2", 3/4", and 1-1/2" trade sizes to accommodate a wide range of liquidtight flexible conduit diameters.
  • Durable Construction: Zinc plated steel body delivers strong corrosion resistance and long-term durability in harsh or exposed electrical environments.
  • Insulated Throat: Integrated insulated throat shields conductor insulation from abrasion during pulling and after final installation.
  • Straight Configuration: Straight, in-line body style provides a direct connection path between liquidtight flexible conduit and enclosures, panels, or equipment.
  • Liquidtight Sealing: Designed to create a secure, liquidtight connection suitable for wet, damp, or outdoor-exposed conduit runs.
  • Zinc Plated Finish: The zinc plated finish adds an additional layer of protection against rust and corrosion in demanding job-site conditions.

American Fittings STR150B – Frequently Asked Questions

1) What conduit does the American Fittings STR-B connector attach to?
The STR-B is built for liquidtight flexible metal conduit (LFMC). It terminates that conduit into boxes, enclosures, panelboards, and equipment housings. It is not a fitting for EMT or rigid pipe, and it is not meant for standard non-jacketed flex, since the sealing gland is sized for the PVC jacket on liquidtight.
2) Can this liquidtight connector be used outdoors or in a wet location?
Yes. The STR-B makes a liquidtight seal on the conduit jacket and is intended for wet, damp, and outdoor-exposed runs, including motor, pump, and machinery drops. Seal the enclosure side as the installation requires, with a sealing locknut or gasket where the box calls for one.
3) What trade sizes does the STR-B liquidtight connector come in?
Three sizes: 1/2 inch (STR50B), 3/4 inch (STR75B), and 1-1/2 inch (STR150B). Match the trade size to the conduit, not to the knockout, then use a reducing washer if the enclosure opening is larger.
4) Does the STR-B have an insulated throat?
It does. The throat is insulated, so conductor insulation is protected from abrasion while you pull and after the wire is in place. That matters most on larger conductors in the 1-1/2 inch size, where the pull tension across the fitting is highest.
5) Is the STR-B steel or die cast, and how does it hold up in a corrosive area?
Zinc plated steel body. The plating gives corrosion protection for industrial and exposed job-site conditions, and steel gives more mechanical strength than a zinc die cast fitting for machinery drops that get bumped. For continuously corrosive or washdown chemical areas, a nonmetallic or stainless fitting is the better call.
6) What part numbers do I quote for American Fittings STR-B connectors?
Order by size: STR50B for 1/2 inch, STR75B for 3/4 inch, STR150B for 1-1/2 inch. All three are the same zinc plated steel straight body with an insulated throat, so a mixed-size order keeps one consistent fitting style across the job.
