Förfarande för tillverkning av rörförbindning eller -muff, där det f inns ett rörformigt plastorgan (1), i vars ända det finns en i denna fastgjuten tätningsring (2), som är fäst vid den inre ytan av det rörformiga organet med hjälp av en stativdel (4) och där det finns en smalare tätande kant (5), som sträcker sig en bit tvärs over den inre delen av förbindningsholken eller -muffen, kännetecknat därav, att tätningsringen (2) tryckgjutes i en första formhalighet, som begränsas av ett spär i gjutkärnan (21,22) och motstaende avskiljbara formavsnitt (23,24), man avskiljer formavsnitten och ästadkonnner en axial relativ rörelse av gjutkärnan och formavsnitten varvid den gjutna tätningsringen halls i splret i gjutkärnan, för formavsnitten (23,24) ihop för att tillsammans med gjutkärnan (21,22) och tätningsringen (2) forma en rörformig andra formhSlighet, tryckgjuter det rörformiga plastorganet (1) i den andra formhäligheten, avskiljer formavsnitten och drar bort gjutkärnan i axelns riktning frän den gjutna förbindningen eller -muffen, varvid tätningsringen pl i och för sig känt sätt ändrar form genom inverkan av gjutkärnan vid bortdragningen av denna.
2. Förfarande enligt patentkravet 1, kännetecknat därav, att man använder en gjutkärna, där det finns tvl gjutkärnsorgan (21,22) bredvid varandra i axelns riktning, mellan vilka det finns ett spar för gjutningen av tätningsringen, och att dessa gjutkärnsorgan (21,22) efter gjutningen av det rörformiga organet avskiljs fran varandra i axial riktning och att gjutkärnan efter detta dras bort fran den gjutna muffen eller förbindningen.
3. Förfarande enligt patentkravet 1 eller 2, vid vilket tätningsringen fram-· ställs av en termoplastisk elastomer, kännetecknat därav, att den termpolastiska elastomerens motstlndsförmaga mot härdning under press förbättras med tvärblndningar Istadkommande stralningsbehandling.
4. Rörmuff eller -förbindning, där det finns ett rörformigt tryckgjutet plastorgan (1), i vars ända det finns en i denna fastgjuten tätningsring (2), som är fäst vid den inre ytan av det rörformiga organet med hjälp av en stativdel (4) och där det finns en smalare tätande kant (5), som sträcker sig en bit tvärs över den inre delen av förbindningsholken eller -muffen, k ä n n e -t e c k n a d därav, att den inre diametern av det rörformiga organet (1)
