Abstract

Oppfinnelsen vedrører en rørkobling for å forbinde en rørformet del (1) med et opptaksstykke (2), hvilken rørkobling omfatter et koblingslegeme (3) som har en utsparring (8), en strammemutter (6a) som har en første gjenge (7a), idet koblingslegemet har en tilsvarende gjenge (4) og en skjærering som er innrettet til å presses mellom et kilelignende veggparti (10) av utsparringen og den rørformede del når strammemutteren strammes. For at rørkoblingen skal kunne strammes for å danne en lekkasjetett og sterk forbindelse ved bruk av et lavt dreiemoment, noe som muliggjør bruk av små verktøyer anvendbare i trange rom, omfatter rørkoblingen en tilleggsmutter (6b) som har en gjenge (7c) hvis dreieretning tilsvarer dreieretningen av den første gjenge (7a), men er mindre, idet strammemutteren omfatter en andre gjenge (7b) som tilsvarer tilleggsmutterens gjenge.
