Hi, has any one had any experience installing Stuart models 5/32 drain cocks? They are supposed to be a 5/32 32 thread, and that is what I cut on a scrap piece of brass. The cock will only thread on about 1 full turn before locking up. I checked every thing twice, but it will not go. Any advice on this would be greatly appreciated. Thanks, John.

I think they are 40 tpi not 32.

Looking at the website it doesn't say but they sell 5/32 x 40 ME taps but not 5/32 Whitworth ones which suggests 40tpi.

Using a thread gauge they are indeed 40tpi. Thanks for your help, I should have checked the thread before posting.
