Need a replacement but the glass tube is 9/16” while the hardware store gauge tube is 5/8”.
However I found the brass nut has a inner plastic liner which is rather hard and brittle. Not sure if I can or should take it out. If I do that then the 5/8” tube can fit. Then I probably should get a rubber washer for it?
How is the glass gauge/washer/nut usually assembled?
Thanks!
