PTFE GLAND PACKING
PTFE Gland Packing is a high-performance compression sealing material manufactured from 100% expanded PTFE fibers or braided PTFE yarns designed for dynamic and static sealing applications. PTFE (Polytetrafluoroethylene) is widely recognized for its exceptional chemical resistance, low friction coefficient, thermal stability, and non-contaminating characteristics.
PTFE gland packing is commonly braided into square or interlock constructions and may be impregnated with silicone oil, graphite, lubricants, or special additives to improve heat dissipation and operational life.
Due to its excellent chemical compatibility and clean sealing properties, PTFE Gland Packing is extensively used in chemical processing, food production, pharmaceutical systems, pumps, valves, and industrial process equipment.

CONCLUSION
PTFE Gland Packing is one of the most versatile compression sealing solutions for industrial applications requiring excellent chemical resistance and low-friction performance. With multiple construction options and reliable long-term sealing capability, PTFE packing helps improve equipment efficiency while minimizing leakage and maintenance costs.
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.
In our PTFE gland packings, the braiding process guarantees a solid but durable substance of constant consistency, ideal for continuous operation at varying temperature.
Our PTFE Compression Packing product line includes valve stem packing, food grade packing and chemically resistant packing for pumps and rotary equipment. The PTFE packings can stand almost every chemical substance known.
The PTFE compression packings offer great temeprature resistance up to +260°C as the PTFE dispersion ensures a low friction finish and pre- vents leakage through the braid.
