Abstract

Oppfinnelsen angår en tetningssammenstilling (40) for montering mellom en øv- re brønnhodekopling (12) og el nedre brønnhodehus eller fallrør (14). Den øvre brønnhodekopling (12) har en nedadvendt avkortet kjegleformet tetningsoverflate (32), og brønnhodehuset (14) har en oppadvendt avkortet kjegleformet tetnings- overflate (34). Tetningssammenstillingen 40 omfatter en metallring (42) med ringformet spor (58) i den for å motta elastomeriske tetningselementer (60), De elastomeriske tetningselementer (60) har utgående lepper (62) for kontakt med og tetning mot tilstøtenije tetningsoverflater (32, 34), og adskilt fra motsatte avkortet kjegleformede overflater (54, 56) på metallringen (42) for å danne elastomeriske tetninger for tetningsoverflatene (32, 34) av brønnhodekoplingen (12) og brønnhodehuset (14).
