Characteristics
GNY-rod packings are rod packings are designed to obtain optimum durability of high wear resistant material by the RN919.
With the larger cross-sectional area than that of SKY-Packings, GNY-rod packings provide extra long time operation.
GNY-rod packings also provide stable sealing performance under considerably eccentric rod action.

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.
- ※For applications without back-up rings, refer to the limiting curve of extrusion of seals to obtain the dimension (φd2).
- ※JIS standard sequence of surface roughness symbols refer to HERE.
