Although YL#2750 is designed specifically
for high temperature, high pressure valves of new concept
perfectly, it can be used for expansion joints handling
high pressure steam., hot gases and oils. The asbestos
fiber is treated with graphite around an inert core of
pure asbestos. It is superior to flexibility and elasticity,
it produces a pliable resilient packing which easily conforms
to the space available in the gland. It has a perfect
sealing effect, because the inert core does not contain
any elastomeric binder, the packing remains stable and
resilient even under the most arduous conditions, including
repeated wetting with condensate. The high tensile inconel
reinforced outer braiding gives the necessary reinforcement
when sealing high pressure. The surface of YL#2750 is
treated with molybdenum disulphide carried in a non-hardening
binder. This reduces friction at the valve stem and enables
the packing to be used safely in contact with stainless
steel.

YL#2055 is made from pure asbestos yarn
which is impregnated with PTFE. It is braided as diagonal
form, is added a special surface treatment of PTFE and
lubricant. YL#2055 is superior to elasticity and lubricating
property. Abrasion of shaft is low and flexibility is
a good. YL#2055 is suitable to food, common chemical,
steam, slovent, paper indusries.
① Rotating pumps, valves, reciprocating and static pumps,
④ agitators, various mixers
① Temperature Range : -75℃ ～ 315℃
② PH Range : 3 - 12
