Water & WastewaterV-Rings
A v-ring seal is a one-piece seal which is mounted on a shaft and seals axially against a counterface and normally rotates with the shaft.
The construction of a v-ring seal is divided into three parts:
a. the body
b. the lip
c. the hinge
ERIKS offers v-rings manufactured with four standard profiles.
- The S type v-rings are designed for shaft sizes up to 200 mm.
- The A type v-rings are designed for shaft sizes up to 2020 mm.
- The L type v-rings are designed for use when the sealing house is limited or as part of a labyrinth sealing application.
- The E type v-rings are designed with a reinforced profile for rigid applications where more axial tolerances are required.
Type A
V-ring type A with bevel back serves as a pressure less, axial rod seal with a very short mounting length, which is clamped on a shaft. The flexible sealing lip seals a counterface at a right angle to the shaft preventing dirt, dust and splash to enter the construction.

Type L
V-ring type L with straight back serves as a pressureless axial rod seal with a very small mounting length, which is clamped on the shaft. The flexible sealing lip seals a counterface at a right angle to the shaft preventing dirt, dust and splash to enter the construction.

Type E
V-ring type E with straight back serves as a pressureless axial rod seal with a very small mounting length, which is clamped on the shaft. The flexible sealing lip seals a counter face at a right angle to the shaft preventing dirt, dust and splash to enter the construction. Thetype E is designed for heavy use or is applied in situations where larger axial tolerances are required. This profile is delivered for shafts from Ø450 to Ø2010 mm.
