SEALING MAIN BODY FOR PIPE CONNECTION

Document Type and Number:

Japanese Patent JPS55149479

Kind Code:

A

Abstract:

A sealing body of an elastomeric material may be attached chemically and/or mechanically to a fixing detail of thermoplastic, reacted elastomer or thermosetting material, which is secured to the end of a pipe section to make a reliably sealed connection. The sealing body has a head section together with a sealing flap; the head section being fitted into one or more recesses in the fixing detail. The sealing body may be injection moulded into the fixing detail or be moulded separately by a variety of methods according to the material used. The fixing detail is a sleeve with a "U" or "J" cross-section, and the expense involved in fitting separately a retaining ring, a sealing body and a fixing detail is reduced considerably. The seal can be made in a single operation. Separate stocks of seals are not necessary and the seal cannot be fitted incorrectly.
