Thomas & Betts LTBUS09L-A LFMC CMP UL 3IN BLU 8M/25FT

The LTBUS09L-A is 3 inch trade size liquid tight flexible metallic conduit, supplied as a 25 ft (8 m) coil. One coil is one orderable unit, so runs longer than 25 feet mean ordering multiple coils or planning couplings at the joints.

It has a galvanized steel core under the jacket, so it is metallic liquid tight (LFMC), not the nonmetallic LFNC type. That matters two ways on the job: the steel core gives the run physical protection and crush resistance that plastic flexible conduit does not, and it needs metallic liquidtight fittings sized for 3 inch, not PVC fittings.

No. The LTBUS09L-A ships as conduit only, a 25 ft coil of 3 inch blue liquid tight. You order 3 inch liquidtight connectors separately, typically two per run plus any additional terminations, and they need to be the metallic liquidtight type to suit the galvanized steel core.

Blue jacket is a color-coded identification choice, not a different construction. The LTBUS09L-A is blue, which crews commonly use to keep one system (a specific circuit type, voltage class, or trade) visually separate from gray conduit running alongside it. If your job spec calls out a jacket color for identification, order to that color across the whole run so the coding stays consistent.

Use LFMC where the run has to flex or absorb vibration and still keep liquids out: motor and pump connections, rooftop HVAC equipment, generator tie-ins, and anywhere alignment between two fixed points is not exact. Rigid and EMT are the better choice for long straight supported runs. At 3 inch trade size this is feeder-scale conduit, so it is usually the short whip between a raceway and a large piece of equipment rather than the whole distribution path.

The catalog number is LTBUS09L-A from Thomas & Betts, which is the 3 inch blue LFMC in a 25 ft (8 m) coil. There are no size or length options under that number, so quoting the part number alone pins the trade size, color, and coil length.
