Description
DBSH721
2:1 Shrink Ratio, Fluoroelastomer Tubing, Flexible, High Temperature, Chemical and Abrasion Resistant
Description
Daburn SH721 is a flexible, fluoroelastomer Viton heat shrink tubing that is used in high temperature applications or where exposure to high temperatures and aggressive solvents is expected and flexibility is desired. It is widely used in hydraulic equipment, aircraft manufacture and ship building.
Features
· Shrink ratio: 50% or more in the radial direction, 20% or less in the axial direction
· Shrink temperature 175? C
· Continuous operating temperature range: - 40°C (-40°F) to 200°C (392°F)
· Excellent abrasion protection while maintaining flexibility at high temperatures
· High resistance to chemicals and oils
· AMS-DTL-23053/13 (Formerly MIL-DTL-23053/13)
· RoHS Compliant
