Would buy this product again if I ever need it.

I closed the radiator steam valve in 3 unoccupied rooms and shut steam air valve but still steam is pushing in thru and entering radiator though in small amount. So I bought this 1/8" plug and replaced the air valve with this plug, open up steam radiator valve- result no more steam coming into the radiator. Once room is occupied will remove plug and put back the air steam valve.
