Characteristics
NMY-rod packings are U-packings with small cross section.
NMY-rod packings are interchangeable with O-rings specified by JIS B2401 P line.
NMY-Packings provide much more stable sealing performance with excellent wear resistance over 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.
