Thomas & Betts TB37SA – Frequently Asked Questions
1) Will a Thomas & Betts TB37SA conduit body work in place of a Crouse-Hinds or Appleton Form 7 body?
Yes. The TB37SA is a Form 7 conduit body, and Thomas & Betts states its conduit bodies and covers are interchangeable with Crouse-Hinds, Appleton and OZ Gedney Form 7 conduit bodies. That means the body and the cover can be swapped against those brands in the same run, so you can standardize on one cover style across a facility that already has mixed Form 7 hardware.
2) What thread type does the TB37SA conduit body use, and do I need bushings for the wire?
Threads are tapered NPT, so it threads directly onto standard rigid or IMC conduit with NPT ends. Integral bushings are built in to protect wire insulation, so you do not need to add separate insulating bushings at the hubs.
3) Does the TB37SA conduit body meet UL and CSA requirements for a government spec job?
The TB37SA is listed to UL Standard, CSA Compliant, and Fed Spec W-C-586D. That Federal Specification callout is the one that usually matters on government and institutional submittals for conduit outlet bodies.
4) Can I use a TB37SA conduit body in a food plant or other washdown/corrosive area?
That is what it is built for. The body is sand cast aluminum, and Thomas & Betts lists it for food and beverage, pharmaceutical, chemical processing and other corrosive environments. Aluminum is the usual choice where steel would rust under frequent washdown, though you still want to confirm the specific chemical exposure suits aluminum rather than a different alloy.
5) Can I hang a light fixture or mount a wiring device on a TB37SA conduit body?
Yes, that is one of its listed uses. A Type TB body acts as a mounting outlet for wiring devices and lighting fixtures, as well as a pull point when conductors are being installed and an access point for splices in branch conductors. It also makes the 90 degree turn in the run, so one fitting handles the bend and the device mounting.
6) Should I use a conduit body like this or just bend the conduit for a 90?
A conduit body earns its place where you need access, not just direction. Bending the pipe gives you a turn and nothing else. A Type TB body makes the 90 degree change of direction and leaves a removable cover, so you get a pull point during the wire pull, a splice point for branch conductors, and access for maintenance or future system changes later. On long or congested runs that access is usually worth more than the saved fitting.
7) Does the TB37SA come with a cover and gasket, or do I order those separately?
Covers for the TB37SA are a separate item. Thomas & Betts builds its Form 7 bodies and covers as an interchangeable system with Crouse-Hinds, Appleton and OZ Gedney Form 7, so you specify the cover (and gasket, where the environment calls for one) to suit the application rather than getting a fixed one with the body.
8) How much does a TB37SA weigh, and how many come in a carton?
Each TB37SA weighs 0.96 lbs. The outer carton quantity is 2, with outer dimensions of 9.75 x 7 x 3.12 inches. Useful if you are planning support spacing on an unsupported fitting or ordering in carton multiples.
