EExd Unions

Raxton Unions are designed to provide a running joint whilst eliminating exposed threads and are particularly suitable for use where a coupler would be impractical.

Unions are available in a variety of thread forms and can be supplied with male to female or female to female thread entries. The female
connection thread of the Union shall step not more than one size up from the male connection thread, or equal to one size up in the case of a thread gender change. Eg M20(M) to M25(F) or M20(M) to 3/4 NPT(F).

Raxton Unions are marked with the appropriate approval number and size.
