PTFE valve stem packing for high-temperature sealing

This PTFE valve stem packing handles continuous temperatures from minus four hundred to five hundred degrees Fahrenheit and pressures up to five hundred psi in both pumps and valves. The material resists the full zero-to-fourteen pH range and carries FDA approval for food-contact applications. Supplied as a seven-foot coil of seven thirty-second-inch square cross-section, it is cut to length during installation.

Industrial maintenance teams sealing aggressive

Maintenance crews working on steam lines, chemical pumps or food-grade valves will find the temperature, pressure and pH ratings cover most severe duties. Operations that require a rated shaft speed or a pre-formed ring rather than bulk coil should look at alternative sealing methods.

Seven-foot coil length determines coverage per

The seven-foot overall length is the single figure that decides how many valve stems or pump glands one pack can serve. Measure the total packing length required across all glands before ordering to avoid shortfalls.

Questions about this item

How often will the PTFE valve stem packing need replacement in a standard pump application?

The PTFE material resists chemicals across the full 0 to 14 pH range and handles temperatures from -400 to 500 degrees F, so replacement depends on your specific service conditions rather than a fixed interval.

What pressure limit will the packing reach first during continuous pump operation?

The packing is rated for a maximum of 500 psi in both pump and valve service, so that pressure ceiling is the primary limit under sustained use.

Does the packing generate noticeable heat or require extra cooling when run all day at the 500 psi rating?

PTFE packing itself produces minimal frictional heat; the 500 degree F temperature rating covers steam and ambient extremes, so no additional cooling is mandated by the packing design.
