This flexible lead-wire replacement probe is ideal for
field installation with existing protection heads or for
extending leads to remote locations. Flexible leads
prevent breakage in hard-to-wire situations. These
probes have 20 AWG stranded lead wire and a 1⁄2 x 1⁄2
NPT hex fitting. Probe length includes 13 mm (1⁄2") of
hex fitting threads.
Over 1 m (40") leads, modify model number, for additional cost per foot. TT-SB: PFA with SS overbraiding, GG-SB: fiberglass with SB
