Type | Profil | Description | Application: | Standard / Description |
A |  | Rubberized stiffening ring | Good static sealing behavior even with low viscosity media and split housings, as well as for housings with increased thermal expansion. | Type according to DIN 3760 |
AS |  | Rubberized stiffening ring with protective lip | See type A, as well as for protection of the sealing lip against foreign liquids, dust and dirt from outside. | Type according to DIN 3760 |
AW |  | Rubberized grooved stiffening ring | Good static sealing behavior even with low-viscosity media and split housings, as well as with housings with increased thermal expansion. The grooving serves to facilitate assembly and prevents skewing and springback.
