Rubber Sealing Ring for Chamfered BSP Ports (Buna N)

Click for a larger picture of Rubber Sealing Ring for Chamfered BSP Ports (Buna N)

These Rubber Sealing Rings can be used to seal chamfered BSP ports. If the port is flat, use a Dowty Sealing Washer (Part No. 3240-Size).

Note: BSP nomenclature can be confusing because the nominal size refers to the inside diameter of the pipe, not the outside diameter of the threads. If you are not sure what size you need, check in our Threaded Fitting Guide.
