RN906

(RF905)

Seals that seal rings made of S-FLON(PTFE) are combined with O-rings made of synthetic rubber. No stick slip even in low pressure and low speed due to small friction characteristics. As seal rings(resin) are hard and lacking in elasticity, sealing performance is inferior a little compared with U-packings. Be careful to handle seal rings as they are easy to be specially influenced by cracks, etc.

RN812 Packings exclusively for pistons and rods compatible in grooves with SKY-Packings. Available for use at -40 to 100 degree C. Unnecessary to replace packings in the specifications of domestic and overseas cold districts. Compared with other U-packings, designed hard to cause stick slip. Laying stress on cold proof, rubber hardness is restrained. Be careful in use under the conditions of high pressure and high frequency.

GPY-Packings[Exclusively for pistons]

RN919Packings exclusively for pistons and rods, respectively, using wear proof material. Section sizes for diameter sizes are made larger than those of SKY-Packings. Durability has been improved. GPY-Packings for pistons are hard to cause damage brought about by back pressure, while GNY-Packings for rods have been improved in sealing performance for good elastic seal materials.
