PTFE-Graphite + Polyamide Fibre Gland Packing(CombinationPacking)
ITEM :- Sigma 234
PRODUCT NAME :- PTFE-Graphite + Polyamide Fibre Gland Packing(CombinationPacking)
BRAND :- SIGMA PLACE OF ORIGIN : INDIA
CERTIFICATION :- API, ISO 9001
APPLICATIONS / USES :-
A Special application performance packing made of PTFE Graphite filament ( The PTFE resin is combined with graphite
& expanded by using the latest technologies resulting in high quality filament) with additional yellow polyamide synthetic fibre reinforced in core &
corners to provide sliding surface and heat dissipation property. The combining benefit of PTFE-Graphite, Polyamide & high temp resistance lubricants
gland packing offers longer sealing ability due to excellent dimensional ability.
Product Description

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 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 aggresive media
- High penetration & abrasion resistance of polyamide fibers ensure corner safety of packing
