Characteristics

PENTA-Seals are rod packings interchangeable with O-Rings specified by JIS B2401 P line.
PENTA-Seals provide incomparably stable sealing performance without the damage from twisting or rolling unlike O-Rings.

Remarks

  • ●Packings should be installed in the direction specified on the above schematic.
  • ●Consider adopting divided grooves if one-piece groove is technically adverse.
  • ※For applications without back-up rings, refer to the limiting curve of extrusion of seals for size (φd2)
  • ※JIS standard sequence of surface roughness symbols refer to HERE.
