Brass straight 12 mm Pipe Union with 1/4th thread.
Union with 1/4" NPTF tapered thread for fuel lines with an internal diameter of 12 mm.
Inlet: 1/4" tapered NPTF
Outlet: 12 millimeter
Please use our superior quality PTFE tape each time that you (re-)assemble screwed connections in the fuel tract in order to properly seal the connection.
As an alternative, you can use our Loctite 243 Thread Locker which will offer the added properties of protecting your connections from undoing themselves.
Despite the barbed edge on these unions, we strongly advise you to secure your fuel lines using jubilee clips.
