PTFE Gland Packing is a type of sealing material used in mechanical devices to prevent leakage of fluid or gases at the point where a shaft or stem passes through a housing or casing. This gland packing is typically made of braided or molded PTFE fibers that are lubricated with a small amount of oil or graphite to minimize wear on the shaft or stem. PTFE Gland Packing is commonly utilized in pumps, valves, and other rotating equipment in chemical, pharmaceutical, food and beverage, and other industries where aggressive or corrosive fluids are present.
