Thomas & Betts LTTUS03B-C – Frequently Asked Questions
1) What size and length is the Thomas & Betts LTTUS03B-C liquid tight flexible conduit?
The LTTUS03B-C is 3/4 inch trade size liquid tight flexible metallic conduit, supplied in a 30 m (100 ft) coil. One coil covers a run of up to 100 feet, so for longer pulls or multiple whips plan your coil count off that length.
2) Is this conduit metal core or plastic flex?
Metal core. The LTTUS03B-C is galvanized steel flexible conduit with a liquid tight jacket over it, not a nonmetallic flex. That matters if your drawing calls for LFMC rather than LFNC, and it is why it can serve as an equipment grounding path where the code and fitting combination allow it.
3) Can I use this 3/4 inch liquid tight in outdoor and wet locations like rooftop HVAC whips?
That is exactly what liquid tight flexible metallic conduit is for. The LTTUS03B-C is the UL listed weather temperature (WTmp) version in 3/4 inch, black, so it is the usual choice for rooftop condenser and air handler whips, pump connections, and other outdoor equipment where vibration and moisture are both in play. Terminate both ends with listed liquid tight fittings to keep the seal.
4) What part number do I give my distributor for 3/4 inch black liquid tight steel flex in a 100 ft coil?
Thomas & Betts LTTUS03B-C. That is the manufacturer part number for the 3/4 inch black UL listed liquid tight flexible metallic conduit in the 30 m / 100 ft coil, and it is the number to quote so you do not get the nonmetallic version by mistake.
5) Will 3/4 inch liquid tight match the flex already run on the rest of my equipment?
If the existing whips are 3/4 inch trade size liquid tight, yes, the LTTUS03B-C matches on size and takes the same 3/4 inch liquid tight connectors. What varies across a building is the jacket color and whether the existing run is steel core or nonmetallic. This one is black jacket over galvanized steel, so it lines up with standard black LFMC rather than gray nonmetallic flex.
6) Should I use liquid tight metallic flex or nonmetallic flex for a motor connection?
Metallic liquid tight, like this 3/4 inch Thomas & Betts LFMC, is the usual pick where the run needs physical toughness and a metal raceway, such as motor and compressor connections exposed to abuse. Nonmetallic liquid tight is lighter, cheaper to pull, and preferred where a metal raceway is unwanted or corrosive chemicals are present, but it gives you no metal path and less crush resistance. If the spec sheet says LFMC, the steel core version is what is being called for.
