Sigma 243 Combination Packing is recommended for Oil & Solvents, caustics, Acids, Alkalies, Dyes, Chemicals Liquid ammonia
& carbonate solution under high pressure conditions, waste water treatment plants. The packing and material is designed for heavy duty industrial use in all
kinds of Aggressive organic / inorganic Chemical Rotary and reciprocating plant pumps & valves, oils, corrosive gases, Dyestuffs, pulp & paper, power generation,
steam valves, metering pumps, reactors, mixers, waste water, bauxite slurries, general slurry, mineral handling slurries and other slurry processing applications.
Product Description
Sigma 243 (CombinationPacking)
A Special application performance packing made of PTFE filament yarn interlaced with blue poliamide aromatic yarn reinforced in core
& corners to provide sliding surface and heat dissipation property.The combining benefit of PTFE, Poliamide & high temp resistance lubricants
offers longer sealing ability due to excellent dimensional ability.

Prime Features
- Long maintenance free service life. Minimal shaft wear and leakage
- Pliable, wear-resistant and dimensionally stable. Rugged and non-toxic
- Extended service life by up to 400% in harsh environments.
- Six times better heat conduction as against pure PTFE packing at comparatively high speeds
- Significantly low thermal expansion thus resisting ‘over expansion’ extrusion under service.
- Suitable to centrifugal & reciprocating pumps even at high pressure
- Excellent in abrasive application. Well proven with aggressive media
- High penetration & abrasion resistance of polyamide fibers ensure corner safety of packing.
