A seal assembly (1) described comprises an elastomeric component (10) having a sealing surface (25) for providing a sealing function, and an energizing band (30), the elastomeric component (10) including an aperture for the energizing band, wherein the energizing band is adapted to fit in the aperture of the elastomeric component (10). In use, an outer surface of the energizing band applies a force to the elastomeric component (10), to deform the (10) elastomeric component to form a seal at the sealing surface. The energizing band (30) component includes non-metallic material. |

1. A seal assembly comprising an elastomeric component having a sealing surface for providing a sealing function, and an energising band, the elastomeric component including an aperture for the energising band having an inner diameter; wherein the aperture of the elastomeric component is generally circular and an outer diameter of the energising band is larger than the inner diameter of the aperture of the elastomeric component; wherein the outer diameter of the energising band is adapted to coaxially against the inner diameter of the aperture of the elastomeric component such that, in use, the energising band applies a sealing force to the inner diameter of the elastomeric component; wherein the energising band component includes substantially non-metallic material; wherein the material of the energising band includes one or more of polyoxymethylene, aromatic polyether, polyphenylene sulphide, aromatic polysulphone, polyphenyl sulphone, polyamide, polyimide or polyamide-imide; and wherein the energising band is flexible. |
