Moulded Part Material
Modified Fluoroelastomer

Moulded parts and shapes with 1
fluoroelastomers are designed to be used
in conjunction with tubing made from
fluoroelastomers or multi-conductor cable 2
jackets and a suitable adhesive. This system
provides excellent resistance to elevated
temperatures and continuous fuel immersion. 3
Available in a wide range of configurations, The
standard colour is black.
