Spiral Wound Gasket is one of the widely used seals, the spiral wound gasket depends on the mechanical characteristics of a formed metal strip which works as a spring, offering a better resilience under fluctuated pressure & temperature. They are widely used in the industrial field and fluid sectors.
Aramid fiber packing braided from high quality Dupont aramid and kevlar fiber with PTFE impregnated and lubricant additive. It is wear resistant but may damage the shaft is not used properly. A minimum shaft hardness of 60HRC is therefore recommended.
Multi-yarns in zebra braided packing consisting of RGS Graphite packing yarns and aramid fiber. Compared to P308B, it has excellent lubrication ability and thermal conductivity.
This packing is a multi-yarns packing. The corners of packing are made of aramid fiber yarns impregnated with graphite PTFE, the friction faces are made of graphite PTFE yarns. This structure enhances the lubrication ability of aramid fiber and improves the strength of the pure graphite PTFE.
Spun aramid packing impregnated with graphite. No harm to shaft, still wearable, good heat conduction.
Spun Kevlar packing braided from high quality Dupont Kevlar fiber with PTFE impregnated and lubricant additive. Compared with other kinds of packings. It can resist more severe media and high pressure.
Nomex Fiber Packing braided from high quality Dupont Spun nomex yarns with PTFE impregnated and lubricant additive, high cross-sectional density and structural strength, good sliding characteristic, gentle on shaft. Compared to kevlar, not hurt shaft, good idea for food industries.
The rubber core can absorb vibration to control leakage. Normally use silicone rubber core.
This packing is a multi-yarns packing. The corners of packing are made of aramid fiber yarns impregnated with PTFE, the friction faces are made of PTFE yarns. This structure enhances the lubrication ability of aramid fiber and improves the strength of the pure PTFE.
