Characteristics
RGY-piston packings are interchangeable with SKY-Packings.
RN923 wear resistant material extended service life.
And in the same time, improved design prevents 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.
- ●φD H9/f8 changes according to the variation of the bearing structure.
- ※JIS standard sequence of surface roughness symbols refer to HERE.

- ★Orders and inquiries are acceptable by part numbers. Part numbers marked ※ have been changed each part numbers. Please check HERE for the previous part number.
- ★Part numbers in blue letters are the products in stock.
- ★Packings with the part numbers in light Italic require the confirmation of their availability prior to ordering. These items are subject to the abolishment without notice. Reclamation of an abolished product requires producing the new tooling at your expense.
- ★Packings with the part numbers including letter B are the improved strength types and incompatible with the groove of SKY-Packings.
- ★Packings are adequately packaged for the optimum storage. Refer to Cautions for the handling and storage.
- ★Please see SKY-packings to obtain information about stock and availability of manufacturing tooling regarding compatible SKY-packings.
- ★Inquiries for HNBR materials:
- ・Please specify material code RP903 or RP902 in addition to the standard part number.
- RP903 is applicable to hign temperature operation and to water polyglycol operating fluid.
- RP902 is the material applicable to both high and low temperature operating conditions.
- ・All HNBR products are manufactured on a made-to-order base.
- ・● indicates manufacturable items. For those items without ● sign, please inquire of us.
- ・Engraved marks may be variant because some dimensions/items are manufactured by using toolings for different materials.
- ★Performance and material tests on packing and seals are also available. Please contact us for more information.
