Sta-Kon RB44-HT HIGH TEMP WIRE JOINT 18-16

The RB44-HT is an 18-16 AWG wire joint, so it covers the stranded 18 and 16 gauge leads you typically find on fixtures, fans, and control wiring. Pushing 14 AWG into it will not give you a proper crimp, and 20 AWG and smaller will not fill the barrel.

Rated up to 302 degrees F (150 degrees C). That is what the HT in the part number means, and it is why this splice gets specified inside recessed luminaires, heater cabinets, and motor junction boxes where a standard nylon splice would be outside its range.

Two conductors, one in each end. It is a butt splice, not a multi-tap connector, so if you need to join three or more leads in a box you want a different connector type.

It carries UL file E9809 and is rated 600 V, which covers standard commercial branch circuits and line-voltage fixture whips. For an MRO or institutional spec sheet, those are the two numbers to cite.

A crimped butt splice like the RB44-HT makes a permanent, vibration resistant joint and holds to 302 degrees F (150 degrees C), which is what you want inside a fixture housing or a ballast compartment. A twist-on connector is the faster choice when you expect to open the joint again or you are joining more than two conductors, since this splice takes two conductors only and a crimp tool to set.

Country of origin on the RB44-HT is the United States, which is what government, school district, and federally funded projects typically need documented before the submittal is accepted.

It is a crimp-type splice, so it needs a terminal crimp tool sized for the 18-16 AWG (white) nylon range, not pliers. Nothing is included with the splice itself. Setting it with the wrong die is the usual cause of a joint that pulls out on the first service call.

The insulating sleeve is nylon, which resists abrasion and cracking better than vinyl and will not split when you flex the lead during install. The body is white, which is the standard color code for the 18-16 AWG range in the Sta-Kon nylon line.
