Die-formed
Flexible Graphite Ring For Exhaust
Item NO:ZD-RG2100
Description:
Die-formed Graphite Rings For Exhaust are made of low-sulphur expanded
graphite with metal wire fillers or binders. The fillers enhance the
strength of the graphite rings.Die-formed Graphite Rings For Exhaust are compressed
in precise moulding tools to the required density.It is mede from the
high purity of the material (>99%), no special corrosion protection is
required. In general, Die-formed Graphite Ring has square section and
also has V-shaped and wedge-shaped section.
The sphere cushion and able to bear the sealed material
graphite of high temperature to pass the special place the metal silk
screen pay attention to die casting but succeed, There is very good
compression elasticity, the system is idea that exhaust First-selected
special-purpose seal.The sphere cushion surface is dealt with by the
ceramic, have good lubrication and seal even more Result, make the
vehicle dispel and rub sound completely in advancing, domestic head of
this technology Create!
