Hubbard Plugs Pierced Catalog



  • Made with holes centered through them.
  • Used in applications where a hole needs to be constricted.
  • Used over a shaft to seal a bearing housing.
  • Can be used as liquid metering units.
  • The catalog lists the range of hole sizes typically run, however almost any plug / hole combination can be produced, with holes down to the very fine (.020”) in some cases.
  • Multiple holes can be produced for special requirements, such as insertion holes for clusters of tubing entering a dust proof assembly.
  • Hubbard Plugs can be perforated with many small holes and set in a counter bored drain hole – in this application Hubbard Expansion Plugs act as a screen.

Stock Materials:

  • Steel: SAE1008/1010 low carbon steel: ASTM#A109 or A569 depending on gage.
  • Aluminum: 1100H14 to ASTM#B209.
  • Brass: ASTM#B36.
  • Stainless Steel: ASTM#A313

* These are materials we stock in various thicknesses. It does not mean we have finished inventory of all plugs in each of these materials.
** Customer specific materials different than those listed above are commonly run.

Finishes:

  • Steel: provided plain finish with a light oil. Expansion plugs can be provided with a wide range of coatings: mechanical zinc (processed in house), electro-zinc, black oxide.
  • Aluminum: provided plain finish. Aluminum plugs are washed in a light mineral spirit in order to remove any solvents or residue.
  • Stainless Steel: Provided plain finish. Stainless Steel plugs are washed in a light mineral spirit in order to remove any solvents or residue. Stainless plugs can be passivated.
  • Brass: provided plain finish. Brass plugs are washed in a light mineral spirit in order to remove any solvents or residue.
