RT-3-NO.2-0-SP (5201974023) - Tyco Electronics

RT-3

Semirigid, flame-retardant polyolefin

heat-shrinkable tubing

RT-3 tubing is ideally suited for wire

strain-relief applications. It provides

excellent strain relief and insulation of

“weak points,” transferring flex stress

away from solder and crimp joints

and other typically sensitive wire-

splice and termination points.

RT-3 is especially well suited for

semi-automated production

equipment requiring tubing with a

tightly controlled expanded

diameter. Sizes and expansion

ratios of RT-3 are available for

specific spade/disconnect terminals.

RT-3 tubing is made from a semirigid,

radiation-crosslinked, flame-retardant

polyolefin. Unlike other typical flame-

retardant tubings, RT-3 tubing is free

of polybrominated biphenyls (PBBs)

and polybrominated biphenyl oxides

(PBBOs). In Europe, these chemicals

are classified as environmentally

hazardous substances.

RT-3 is UL-recognized in all colors

and CSA- certified in black at

125°C, 600 V.

Temperature rating

Full recovery temperature: 135°C

Continuous operating temperature: –55°C to 135°C
