1 1/2 inch threaded connection, "Flat Type" — is a gasket necessary?

BONI-42295-524 Sealing Type : Flat Thread Direction : Male × Female Thread : 1 1/2"

Is a special sealing agent necessary when installing this fitting, or is tightening it firmly enough?

Kundendienst

Response

Tightening it firmly alone is not enough, as the threaded connections of the fitting are not self-sealing. For a tight connection, it is mandatory to use a suitable thread sealing material such as PTFE tape or hemp.

Anja M.

06 Sep

BONI-42295-524 Sealing Type : Flat Thread Direction : Male × Female Thread : 1 1/2"

The connection is leaking despite new Teflon tape, could it be the thread or the installation?

Kundendienst

Response

The external threads are tapered and the internal threads are parallel/cylindrical. Ensure that the sealing material such as Teflon tape or hemp is applied correctly and sufficiently on the thread, as the threaded connections are not self-sealing.
