Thomas & Betts 9306 Liquidtight Flexible Metal Conduit Fittings

It is built for 5/16 inch nominal protective metallic hose. Small-bore stuff, the kind used for instrument and sensor leads rather than branch circuit runs, so check the hose OD you are terminating before ordering a box of these.

Yes, it is approved in combination with protective conduit under UL. CSA approval in combination is not carried on this item, so on a Canadian job where CSA marking is required on the fitting/conduit assembly, source a CSA-approved combination instead.

Straight body. If the run needs to turn at the enclosure wall, a straight fitting like the 9306 will force a bend radius in the hose right at the termination, which small-diameter liquidtight does not always tolerate. Spec an angled connector for tight cabinet entries.

Steel housing with a nylon insulated throat, so the wire passes over insulating material rather than a bare metal edge. The steel body is what carries the mechanical load and the ground path continuity through the fitting; the nylon is there to protect conductor insulation at the point where it turns into the box.

It is a multi-piece fitting, not a one-piece body, so it comes apart for installation: you pass the components onto the hose and draw them up on the thread. The thread does not revolve on this design, meaning you turn the fitting itself to tighten rather than spinning a free-running collar, which matters when the hose is already anchored at both ends.

Order Thomas & Betts part 9306. That single number covers the straight steel, nylon insulated, M16 x 1.5 fitting for 5/16 inch protective metallic hose, there are no separate finish or size suffixes to call out.

They pack 25 to the inner carton and 300 to the outer, and run about 6.25 lbs per 100 pieces. Useful if you are setting a min/max on a panel shop shelf, one outer case covers 12 inner boxes.
