Rod Seals
Sealing ring: F-PTFE
Elastomer: NBR or EKM
Share:
Features
The sliding material is F-PTFE and the sealing ring features low friction resistance, so it can eliminate the crawling and ensure high abrasion resistance. Since single sealing features bidirectional sealing ability, the installation space can be saved; this sealing ring can be installed on the groove of the O-ring and features lower sliding friction compared with the O-ring, so it can guarantee high durability;and can also be used for pneumatic equipment.
Please refer to the standards of SPNC series of NOK Company and RDD series of Trelleborg Company when designing and selecting.
