2, Flexible Graphite Packing

   Item: HY-S689

Description:Braided from low-sulphur expanded graphite yarns, which are reinforced by cotton or glass fiber. It has a very low friction, does not damage shafts or stems. It shows good thermal and chemical resistance and high elasticity.

CONSTRUCTION:

Other reinforcement materials are also available:

Glass fiber--------High strength, lower cost

Carbon fiber------Less weight loss

HY-S689F --Flexible Packing with Corrosion Inhibitor

Corrosion inhibitor acts as a sacrificial anode to protect the valve stem and the stuffing box.

APPLICATION:

HY-S689 & HY-S689F is a multi-service packing capable of a wide variety of uses throughout a plant. It can be used in valves, pumps, expansion joints, mixers and agitators in high-pressure, high-temperature hostile environments of hydrocarbon processing, pulp and paper, power stations, refineries and industries where effective sealing is vital.

Precaution: in oxidizing environment.

3, Graphited PTFE Packing

   Item: HY-S684G

Description:Braided from graphited PTFE (gPTFE) plain yarn. The packing is soft, with low density There are no free particles of graphite on surface and therefore no contamination can occur. Both are economical "CGFO".

CONSTRUCTION:

HY-S684G A is a packing with A grade of quality, the yarn with good tensile strength, and excellent thermal conductivity.

HY-S684G B is economical gPTFE packing, braided from normal graphite PTFE yarn

4, Carbon Fiber Paking

   Item: HY-S691

Description:Braided from strong carbon continuous yarns after softening, impregnated with proprietary lubricants and graphite particles, which fill voids, act as a break-in lubricant, and block leakage.

CONSTRUCTION:

HY-S691W Carbon Fiber Packing Reinforced with Inconel wire

The Inconel wire reinforcement provides increased mechanical strength, usually for static.

5, Aramid Fiber Packing

   Item: HY-S686

 Description:Braided from high quality Dupont Aramid/Kevlar fiber with PTFE Impregnation and lubricant additive. Extremely hard wearing. It shows good chemical resistance, high elasticity and very low cold flow. It is wear resistant but may damage the shaft if not used properly. A minimum shaft hardness of 60HRC is therefore recommended. Compared with other kinds of packing, it can resist more severe media and higher pressure. The packing is also lubricated with a silicone-based compound for quick and easy break-in.

HY-S686L Aramid fiber packing with an inert lubricant

Without PTFE impregnation, An extremely durable, highly abrasive resistant packing, It is ideal for slurry service application.

6, Injectable Packing

   Item: HY-S699
