A ring like seal assembly (44) for a wellhead assembly (38) that seals between a pair of coaxial tubulars (40, 42). The seal assembly (44) includes a spring member (54) for exerting an axial force on the seal. The spring member (54) projects from an end of the seal assembly (44) substantially parallel to the axis of the seal assembly (44) and is compressed when installing the seal assembly (44) between the tubulars ((40, 42). Compressing the spring member (54) maintains an axial force on the seal assembly (44) to keep the seal assembly (44) radially deformed so that it can maintain sealing contact with both coaxial tubulars (40, 42). |
