Hello, Thank you for your enquiry. Generally speaking, the threads on an external surface are considered male, so yes this does have a male Brass thread. Thank you for contacting Screwfix Q&A

Hello robine, No, this will not fit onto a 15mm pipe. It is not supplied with a compression nut and olive. Thank you for using Q&A

Hello Wellhard63, Yes, as far as we are aware, the Type A is a better design and plumbers prefer them. Type A has a gland to prevent water from running down the threads and out when you open the valve, whereas Type B does not have this gland. When you open a Type B to drain a central heating system, a lot of water runs down the threads and onto the floor instead of going down the drain hose. Thank you for using Screwfix Q&A.

Hello AndyM12, We would recommend item 38428. Thank you for using Screwfix Q&A. A.K.C.
