  This product is made from graphite tape which is twisted, braided and treated with corrosion inhibitors and a blocking agent. It has the superior leakage and emissions control ability of die-formed graphite rings it is convenient, economical and easy to replace. This product dissipates produced heat from installation effectively, also the self-lubricating quality of graphite protects shaft sleeve and extends packing life. This product forms a homogeneous mass under various conditions, so it can be used suitable for high temperature and pressure steam applications.


YL#3000-I which is impregnated with inconel(Fe-Ni-Cr) is made for high temperature and pressure valve. YL#3000-I can be supplied in continuous lengths, cut and formed into rings with specific stack heights to suit customer requirements, so inventory cost can be reduced. YL#3000-I is suitable for both new and retrofit valves. YL#3000-I seals even with stem and housing imperfection, also it is safe at fire. Physical properties of YL#3000-I are superior than other products. Also, it is very low fugitive emission levels, reduces maintenance cost, and increases operating efficiency. It's suitable for steam, water, hot oils, solvents, hydrocarbons, and alkalis(exception : strong oxidizing compound).
① Petrochemicals ② Hydrocarbons ③ Refineries 
④ Power Stations ⑤ Agitators  ⑥ All kind of steam valve
① Temperature Range :
from -200℃ to +500℃ (in oxidizing conditions)
3000℃ (in inert, non-oxidizing conditions)
up to +650℃ (in steam)
② Pressure : up to 300 kgf/㎠
③ PH Range : (see suitable media) 0 - 14

YL#3000 has the maximum leakage controlling ability which is almost same ability of the die-formed graphite rings, and also, the braided construction has the flexibility which is lack in universal die-formed rings. Therefore, it is easy to install and isn't breakable. When you install it, you don't need to measure anything. Also, it is very exclusive product which can be used extensively for valves and pumps. It isn't expensive, and any other dies or graphite molded rings are not needed. Also, the incorrect ring size can not be the causes of any dangerous accidents.

YL#3000 is used to installation of petrochemicals, hydrocarbon. corrosives in refineries, power plants, pulp and paper mills.

YL#3000-M is produced by several layers of expanded graphite core that is reinforced with a wire mesh covering. Its blocking agents are more enhanced.
The packing exterior is densely impregnated with lubricating agents and a corrosion inhibitor to reduce stem friction. It isn't transformated and abraded, if it's used for a long time, and dissipates produced heat from installation effectively.
YL#3000-M has flexibility, and strong property, also it is safe at fire. It works very well in high temperature, high pressure conditions, so it always maintains most suitable condition of sealing maintenance and leakage prevention effect. YL#3000-M provides the most satisfaction for customer by best price. It is used for valves of Power Stations, Petrochemical Plant, and Refineries.
