## Abstract

A seal including: an annular jacket including a heel, a first lip, and a second lip defining an annular recess; and an insert including at least 3 prongs disposed within the annular recess contacting the heel, the first lip, and the second lip.

## Claims

### Claim 1

A seal comprising:
an annular jacket comprising a heel, a first lip, and a second lip defining an annular recess; and
an insert comprising at least 3 prongs disposed within the annular recess contacting the heel, the first lip, and the second lip, wherein the insert contacts at least one of the heel, the first lip, or the second lip along a planar edge, wherein the insert comprises a first prong, a second prong, and a third prong, and wherein the insert is disposed entirely within the annular recess with no portion of the insert forming an exterior surface of the seal.

### Claim 2 (depends on 1)

The seal according to claim 1, wherein the insert is a Y-shaped insert.

### Claim 3 (depends on 2)

The seal according to claim 2, wherein the first lip has a length LFL wherein the second prong contacts the first lip at least 30% of the length LFL.

### Claim 4 (depends on 2)

The seal according to claim 2, wherein the second lip has a length LSL wherein the third prong contacts the second lip at least 30% of the length LSL.

### Claim 5 (depends on 1)

The seal according to claim 1, wherein the insert is an X-shaped insert.

### Claim 6 (depends on 1)

The seal according to claim 1, wherein the insert comprises a metal.

### Claim 7 (depends on 1)

The seal according to claim 1, wherein the insert comprises a ceramic.

### Claim 8 (depends on 1)

The seal according to claim 1, wherein the insert comprises a polymer.

### Claim 9 (depends on 1)

The seal according to claim 1, wherein the intersection of the first prong and the second prong form an angle alpha, wherein a is no greater than 180 degrees.

### Claim 10 (depends on 1)

The seal according to claim 1, wherein the intersection of the first prong and the third prong form an angle delta, wherein delta is no greater than 180 degrees.

### Claim 11 (depends on 1)

The seal according to claim 1, wherein the intersection of the second prong and the third prong form an angle theta, wherein theta is no greater than 180 degrees.

### Claim 12

A seal comprising:
an annular jacket comprising a heel, a first lip, and a second lip defining an annular recess;
an energizer disposed within the annular recess adjacent to at least one of the first lip or the second lip; and
an insert comprising at least 3 prongs disposed within the annular recess contacting the heel, the first lip, and the second lip, wherein the insert contacts at least one of the heel, the first lip, or the second lip along a planar edge, wherein the insert comprises a first prong, a second prong, and a third prong, and wherein the insert is disposed entirely within the annular recess with no portion of the insert forming an exterior surface of the seal.

### Claim 13 (depends on 12)

The seal assembly according to claim 12, wherein the annular recess comprises an inner cavity housing a prong of the insert.

### Claim 14 (depends on 13)

The seal assembly according to claim 13, wherein the prong of the insert is fixed within the inner cavity.

### Claim 15 (depends on 12)

The seal assembly according to claim 12, wherein a prong of the insert contacts the first lip to provide a biasing force on the first lip.

### Claim 16 (depends on 15)

The seal assembly according to claim 15, wherein a prong of the insert contacts the second lip to provide a biasing force on the second lip.

### Claim 17 (depends on 16)

The seal assembly according to claim 16, wherein the radial biasing force against the first lip is different than the radial biasing force against the second lip.

### Claim 18 (depends on 12)

The seal assembly according to claim 12, wherein the first lip is located exterior to the second lip.

### Claim 19

A seal assembly comprising:
a first member;
a second member; and
a seal disposed radially between the first member and the second member, the seal comprising:
an annular jacket comprising a heel, a first lip, and a second lip defining an annular recess;
an energizer disposed within the annular recess adjacent to at least one of the first lip or the second lip; and
an insert comprising at least 3 prongs disposed within the annular recess contacting the heel, the first lip, and the second lip, wherein the insert contacts at least one of the heel, the first lip, or the second lip along a planar edge, wherein the insert comprises a first prong, a second prong, and a third prong, and wherein the insert is disposed entirely within the annular recess with no portion of the insert forming an exterior surface of the seal.
