I replaced the 13-year old 1/2 inch drain valves to my 13-year old boiler. The original valves were male threaded valves but at the time before disassembly, I thought that they were female threads so I bought and installed female valves using 1/2 inch close nipples. Now after I installed the valves using plumbing thread sealant, I am wondering how long the 1/2 inch close nipples will last before/if they corrode. One nipple connects into a black iron t-joint (at the water inlet end) and the other into a black iron elbow, that connect to the boiler. Should I have just used male threaded valves instead? Does it make a difference? It just seems now after installation, that male threaded valves have beefier threads than the nipples.

Don't worry about it. They will probably outlive the boiler,as long as they're not leaking.Make sure there is a means of automatically removing air from the system, such as a spirovent or scoop.
