Product Description

APPLICATION

Twinfit Fluor Blue silicone bellows provide an extremely flexible connection for cooling water systems, clean air supply, and turbo air charge systems. This type is oil resistant and suitable for applications with very high temperatures.

  • Temperature range from –60°C up to +250°C
  • Maximum working pressure 4 bar at 120°C

CONSTRUCTION

The Twinfit silicone bellows are constructed with:

  • High-quality Black Fluor silicone rubber inner tube
  • Heavy-duty DuPont Nomex cord reinforcement
  • Blue silicone rubber cover
  • Three stainless steel reinforcement rings on the outside
  • Special beads on each end for positioning the clamping bands


CLAMPING BANDS

We recommend using our heavy-duty clamping bands. The clamping bands are either made of zinc-plated carbon steel or full stainless steel.


MOVEMENTS

Compression and elongation 13 mm. Lateral 3 mm.


GENERAL

A minimum distance of 50 or 69 mm, depending on bellow size, between the pipe ends is needed for secure operation. On a TwinFit Fluor Blue clamping bands should be used.
