PTFE packing is a sealing material used in pumps, valves, and other industrial equipment to prevent leaks, offering excellent chemical resistance, low friction, and high-temperature stability.

Graphite packing is often used in steam valves due to its high-temperature resistance, self-lubricating properties, and ability to maintain a reliable seal under thermal cycling. However, its suitability depends on factors like steam quality, pressure, and the risk of oxidation or galvanic corrosion when paired with certain stem materials. Proper selection and installation can ensure long service life, but careful evaluation is needed to avoid premature leakage or stem damage.

Discover the typical service life of graphite PTFE packing and learn what factors influence when it needs to be replaced.
