Where's the nut? By P in Mpls on 2/13/14

This switch works well, exactly as advertised. Like others, I wish it would come with a nut. The only FPT fitting I can find is brass, which is unacceptable for a reef tank. Even a link on where to find one would be helpful.

I have used several to measure water levels for a Neptune ACIII for a few years without issue. Other reviewers have noted that these do not come with a nut. This is because they do not understand NPT (national pipe thread) vs. straight thread standards (such as machine screw or bolt threads).
NPT threads are used with pipe fittings; they are tapered, and are designed to seal when screwed into a mating fitting without requiring a nut. As such, these switches attach to a 1/8" NPT female connection.
Make sure you can find the nut first By Mrk on 5/5/13

This seems like a nice switch. It's bigger than most but the deal breaker is the not included mounting nut. Since BRS and even the manufacturer don't sell the nuts it should have made me suspicious. Home Depot, Lowes, Ace, Amazon and even Fastenal don't have the nuts either. So I'm forced to return mine.
Nice switch, does the job. Easy to install. By Kevin on 2/7/12

The switch is great. I put my ATO together in a couple of hours and it works well. The switch is smooth and doesn't stick. I just wish it had a nut at the top to help mounting it to the rack.
