I want to install multiple pressure gauges inline to monitor pressure drop due to friction loss resulting from iron buildup constricting the pipe ID. Since inline gauges are often used to monitor inline filters, one might think such a fitting would be easy to find but my google fu must be failing.
A reducing 1" tee with a 1/4" side port would work but it seems to be as rare as hen's teeth. I realize that I could use reducing bushing in the side port of any Tee but that then adds to the cost.
Ideally I would prefer brass or SS but they are expensive. I thought of buying brass check valves with the 1/8" and/or 1/4" side ports and just taking out the innards but those too I cannot find locally and after I add on the shipping costs to order them online, those too start getting expensive.
I can find the brass check valves locally without the side ports and though I could drill and tap the 1/4" FPT to mount the gauge but then got to thinking that maybe I could do the same thing with a 1" threaded shed 80 PVC coupling. I tend to shy away from PVC or any "plastic" fitting with FPT as they have a tendency to break if over-tightened but perhaps sched 80 would be strong enough. I'd prefer sched 120 but can't find it locally.
I think the threads on most "plastic" fittings are formed by injection molding but wonder if they can be cut with a tap?
