The RSA seal has a dynamic lip shorter than the static one and it is used in cases of high rod misalignments and possible high pressure.
The proposed material is a “C0” type polyurethane, with high elasticity modulus, low compression-set
and high abrasion resistance.
The hardness is 93 Shore A ± 2.
Compound reference: C0
To prevent any damage to the seal, remove any flash and cutting edges in the housing and on the rod.
The seal should always be lubricated before assembling in order to have easier insertion of the rod.
