Moulded Parts
-4
Moulded Part Material
Flexible Polyolefin

1 Designed for use in general harnessing
applications where toughness is required and
systems are occasionally exposed to fluids or
2 heat. The adhesive-lined parts provide excellent
sealing and strain relief at connector-cable
terminations and transitions. A wide range
3 of shapes are available in this material. The
standard colour is black.
