En nesetetning for å danne en fluidforsegling med en tetningsflate i en boring. Nesetetningen er spesielt egnet for bruk under forhold med høyt trykk og høy temperatur. Nesetetningen omfatter en betydelig deformerbartetningsring, som kan danne en fleksibel fluidforsegling med tetningsflaten, og en hovedsakelig ubøyelig ring, som hindrer eller begrenser ekstrudering av den betydelig deformerbare tetningsringen i miljøer med høy temperatur og/eller høyt trykk. A nose seal for forming a fluid seal with a sealing surface in a bore The nose seal is particularly suitable for use in high pressure and high temperature conditions. The nose seal includes a substantially deformable sealing ring, which can form a resilient fluid seal with the sealing surface, and a substantially rigid ring, which prevents or limits extrusion of the substantially deformable sealing ring in high temperature and/or high pressure environments.
