Member Jonathan Kay Posted March 7, 2017 Member Share Posted March 7, 2017 Have you still got the old one?M12, unless it's M8, except for early 1.4s?Discussion of species of seals.Jonathan Link to comment Share on other sites More sharing options...
revilla Posted March 7, 2017 Share Posted March 7, 2017 ... unless somebody in the past has stripped the thread and drilled and tapped it larger ... Link to comment Share on other sites More sharing options...
Area Representative Nick Bassett Posted March 7, 2017 Author Area Representative Share Posted March 7, 2017 OK thanks both... mine is a 1994, so could be classed as an early one!Not a big problem I guess as they are hardly expensive! Link to comment Share on other sites More sharing options...
Wrightpayne Posted March 7, 2017 Share Posted March 7, 2017 If youve got the old one just re- anneal it Link to comment Share on other sites More sharing options...
TomB Posted March 7, 2017 Share Posted March 7, 2017 I was going to suggest heating it in a blow lamp, it thought I was imagining things! Link to comment Share on other sites More sharing options...
SM25T Posted March 7, 2017 Share Posted March 7, 2017 The only way to be sure of what size is to remove the plug and check it. Link to comment Share on other sites More sharing options...
Wrightpayne Posted March 8, 2017 Share Posted March 8, 2017 I've hooked them on a long bit of wire and heated it using the gas hob Link to comment Share on other sites More sharing options...
elie boone Posted March 8, 2017 Share Posted March 8, 2017 If you want to make copper soft again heat it and dump it in cold water. Link to comment Share on other sites More sharing options...
ECR Posted March 8, 2017 Share Posted March 8, 2017 But don't overheat it as it's possible to melt it. Cherry red is fine.Then quench in water or let it cool naturally, either method is fine for copper Link to comment Share on other sites More sharing options...
