Characteristics
GPY-piston packings are designed to obtain optimum durability by the high wear resistant material.
With the larger cross-sectional area than that of SKY-Packings,
GPY-piston packings provide an extra long operation time and prevent the damage by back pressure.

Remarks
- ●Packings should be installed in the direction specified on the above schematic.
- ●Consider adopting split grooves if one-piece groove is technically adverse.
- ●When a high pressure back-up ring is not used, φDc and Gc are not necessary.
- ●φD H9/f8 changes according to the variation of the bearing structure.
- ●For applications installed in combination with wear rings, refer to the dimension table of the applicable wear rings.
- ※JIS standard sequence of surface roughness symbols refer to HERE.
