The present invention is a method of sealing threaded connections of plastic fittings with other plastic fittings, or with fittings of any other materials, in order to ensure a non-leaking connection without applying any additional sealing means. This is achieved through the incorporation of an elastomer sealing material on the threads of one of the plastic fittings during its production process, using a two stage injection moulding method. |
