AV 290T 90 degree Screw Outlet

Harmer Aluminium Roof Outlet (Domed Grate)

90º Screw outlets have a female socket with parallel thread to BS EN 10226-1 for direct connection to threaded tube conforming with BS EN 10226-1.

This tube is supplied with BS EN 10255 taper male thread which ensures a completely watertight joint when screwed home into the socket outlet.

Threaded outlets are particularly recommended where a connection to the outlet occurs within the thickness of a concrete slab.

In such cases, a threaded connection will create a completely gastight seal within the slab.

Harmer Roof AV threaded outlets can be connected to socketed and socketless cast iron pipework, HDPE pipework and PVC pipework by means of the Harmer Roof Threaded Spigot Adaptor with appropriate Harmer coupling.
