PTFE and Graphite Gland Packing

PTFE compression packing, are made of Polytetrafluoroethylene, is known for its exceptionally high resistance to chemicals and low friction. PTFE Gland packings are made of specially selected polytetrafluoroethylene (PTFE) filaments or exfoliated graphite acrylic fibre.

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. Being hydrophobic, non-wetting, high density and resistant to high temperatures, PTFE is an incredibly versatile material with a wide variety of applications, though it’s perhaps best-known for its non-stick properties.

Graphite packings are self-lubricating, dimensionally stable, impervious to gases and fluids, and corrosion-resistant. Graphite packings offer excellent sealing capabilities under extreme conditions for longer equipment life and less maintenance.

Gland packings are a traditional and still popular way of solving dynamic sealing constructions. This type of seal damps leakage between the moving part and the housing and is essential for the efficiency of mixers, pumps, valves and other industrial equipment in rotary motion.
