Sigma 225 Combination Packing PTFE + Polyamide Fibre Gland Packing
ITEM : Sigma 225

PRODUCT NAME : Sigma 225 CombinationPacking PTFE + Polyamide Fibre Gland Packing



APPLICATIONS / USES : A Special application performance packing made of  combination of Pure PTFE fibre with additional polyamide synthetic fibre reinforced in core & all four corners to provide sliding surface and heat dissipation property. The combining benefit of pure PTFE, Polyamide & high temp resistance lubricants gland packing offers longer sealing ability due to excellent dimensional ability.

Best gland packing for NH3 feed pumps.
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 packings at comparatively high speeds.
Significantly low thermal expansion thus resisting ‘ over expansion’ extrusion under service.
Suitable to centrifugal & reciprocating pumps even at high pressure
PTFE Graphite fibre at faces enhance low friction  for shaft / sleeve safety
Excellent in abrasive application. Well proven with aggressive media
High penetration & abrasion resistance of polyamide fibers ensure corner safety of packing

Available on demand: Square Section 6 mm sq upto 38 mm sq.sq.
