Standard Shapes

Originally used as replacements for AN-6225 packings in rubber or leather, this low-profile design has become the industry standard for PTFE packing sets. The included angle on the convex side of each "V"-ring (and the male adapter) is larger than the included angle on the concave side (and the female adapter). Compression of the set causes the lips of the rings to flare in the radial directions, thus creating the desired seal.

This higher-profile design minimizes the number of rings needed to fill a stuffing box. The rounded top of each ring forces the lips of the adjacent ring to flare in the radial directions, creating the desired seal. The large void areas permit thermal expansion where binding may be an issue.

The thinner "legs" of this higher-profile design allows for sealing with lower compression of the packing set.

The heavier walls and cross-section of this design will withstand higher operating pressures.

This design incorporates an internal rubber "O"-ring as an energizer, which helps compensate for the cold-flow inherent in PTFE under pressure. When properly compressed the rubber component is completely encapsulated and thereby insulated by the PTFE from exposure to undesired substances.

These notched wiper rings can be used in combination with any of our -25 Series rings. Various configurations are possible to make replacement control-valve packing-sets for many valve manufacturers’ products.

These concentric ribbed manifold seals (gaskets) are used in a variety of applications. They are compression-molded of virgin-grade, unfilled, FDA compliant PTFE.
