PTFE 4:1 Shrink Tubing

PTFE Teflon 4 to 1 Shrink Tubing
Material Properties
Zeus® PTFE (polytetrafluoroethylene) 4:1 heat shrink tubing provides an effective technique for encapsulating and protecting wires, cables and other critical components exposed to volatile environments. Provided in an expanded state, this material can be shrunk through heat application to create tight, protective sleeve for material subjected to extremes of heat, corrosion, shock, moisture or other acute environmental conditions. PTFE possesses the lowest coefficient of friction making it ideal for applications needing lubricious material. It is chemically resistant to all common solvents, acids and bases, chemically inert and has a high dielectric strength over a broad temperature range. This tubing can be sterilized chemically and is auto-clavable. The minimum shrink temperature for PTFE tubing is approximately 654°F to 670°F (346°C to 354°C).

Markets & Applications ▼
PTFE heat shrink tubing serves critical functions in several industries including the aerospace, automotive, electrical, fluid transfer, fiber optics and medical fields. Applications specific to the medical field include use in electrosurgical instruments, medical components and devices and laparoscope instrument insulation. Please contact us for assistance in choosing the best products for your application.

Custom Fabrication & Contract Manufacturing ▼
In addition to Component Supply's offering of PTFE heat shrink tubing in 4-foot lengths, this product can be ordered in spools and in various colors for production run quantities. Our proprietary processes and equipment give us the expertise to produce custom lengths precisely fitting the items needing coverage.
