Abstract
A seal assembly comprising a first back-up ring, a second ring member, and a plurality of v-rings arranged in a stacked configuration and interposing the first back-up ring and the second ring member. The at least one of the plurality of v-rings being a v-seal formed from a material that comprises a polyarylether ketone (PAEK), the material having a tensile modulus equal to or less than 3,900 MPa at room temperature.
Claims22
A seal assembly, comprising:
- a first back-up ring;
- a ring member;
- and
- a plurality of v-rings arranged in a stacked configuration and interposing the first back-up ring and the ring member, the plurality of v-rings including a first v-ring in direct contact with a second v-ring,
- wherein the first and second v-rings are each formed from a material that comprises a polyarylether ketone (PAEK), the material having a tensile modulus equal to or less than 3,900 MPa at room temperature.
