Tyco Electronics’ Raychem brand FL2500 heat-shrinkable tubing is a flame-retardant, adhesive-lined polyolefin tube designed to seal and insulate electrical splices, fusible links, and other in-line electrical/electronic components. It’s suitable for use in automotive wiring harnesses and other wiring and harnessing applications in many harsh environments or applications that require robust environmental sealing and flame-retardant performance.
The economical and effective sealing attributes of FL2500 heat-shrinkable tubing provide sealing from moisture, oils, and other chemicals. As the tube is heated to it's full recovery temperature of 135°C, the polyolefin tube shrinks and the adhesive lining melts, flowing into all voids of the area being sealed.
Available in four diameter sizes ranging from 7.62 mm to 17.79 mm and shrink at a nominal 4:1 ratio, the FL2500 is black and comes in standard cut lengths of 27 mm, 50 mm, 65 mm and 1220 mm.
