As aramid-filament packings have a high
tensile intensity, it is superior to tensile intensity and abrasion
resistance. Almost all products are treated with inactive lubricant,
PTFE or special lubricant. Products are not contaminated by graphite.
Aramid packings are used for various class industries widely.

As YL#1000's surface is very a soft, it
is especially useful for high-speed installation which
treats abrasive media. YL#1000 is easy to install as die-formed
rings and it has the construction that side of contact
at shaft is lubricated continuously. YL#1000 is used for
sugar-manufacture, pulp industry, wastewater and treatment
field.
① Centrifugal pumps, reciprocating pumps, rotating pumps

YL#1500 is diagonally braided with aramid
fibers that tensile intensity is high and PTFE fibers
which is special common packing. YL#1500 is suitable to
the field that is needed anti-abrasive common packing.
① Musticators that is used to chemical industry
② Mixers ③ Dryers
① Temperature Range : -100℃ ～ +280℃
② Pressure : 20 kgf/㎠ (centrifugal)
③ PH Range : 1 - 13
④ Speed : 25 m/s

YL#1550's some parts in core and at corners
consist of aramid fiber, and the other parts consis of
PTFE fiber which is mixed with PTFE dispersion. The packing's
surface is treated an inactive lubricant. YL#1550 is planned
and developed as shaft or piston for being suitably used
in the mechanical environment which has unfavorable conditions,
also it's developed as reciprocating machine which works
under high pressure of 500 kgf/㎠ for being used in the
bad working environment.
YL#1550 is suitable for petrochemical industries that
it treats emulsified water, demineralised water, dairy
homogeinsers, oils, volatile liquid, hydrocarbons, food,
medicines, various chemical liquid and installations
which treats carbon gases, ammonia at a fertilizer industries.
① Reciprocating pumps, low-speed rotating pumps
② Mixers ③ Agitators ④ Atomic pile
① Temperature Range : -100℃ ～ +280℃
② Pressure : 500 kgf/㎠ (reciprocating)
③ PH Range : 1 - 13
④ Speed : 10 m/s

As YL#1700 is usable packings in various
parts, it disperses heat which is produced by friction
very effectively. This product's characters are low energy
absorption in stuffing box, high force of heat dispersion,
flexibility, density, easy installation, removement and
easy leakage control. YL#1700 is used to substance being
polluted, liquid of corrosion and viscosity, paper, pulp,
oils, hydrocarbons, food and medicine industries that
treat chemical liquid. Especially, YL#1700 is useful at
high-speed rotational field of grinding media.
① Rotational pumps, reciprocating pumps ② Agitators ③
Mixers
④ Pulp grinder
⑤ Refineries
① Temperature Range : -100℃ ～ +280℃
② Pressure : 250 kgf/㎠ (reciprocating)
③ PH Range : 1 - 13
④ Speed : 25 m/s

YL#1750's parts in core and corners consist
of aramid fiber, and the other parts consist of PTFE fiber
which is impregnated with PTFE dispersion. The packing's
surface is treated an inactive lubricant. YL#1750 is used
at various fields that treat air, oil, corrosion and weak
acids. Especially, it is suitable for installation that
treats grinding media.
① Rotational and reciprocating pumps
② High pressure plunger pumps and sticking installation
① Temperature Range : -100℃ ～ +280℃
② Pressure : 500 kgf/㎠ (reciprocating)
③ PH Range : 1 - 13
