Replacing pressure gauge

[HoltPool]

I noticed that my pressure gauge has moisture in it. It still works but I was thinking of replacing it with a glycerin filled one from this site.

1. It says freeze protected to -4F. I live in PA and it can get lower than that but not often or for extended periods of time. Should I not use this gauge?

2. Will this gauge work on all Hayward filter models?

Thanks.

You can remove the gauge when you winterize

Should unless they have a mongrel fitting out there.

I have a Hayward Sand Filter and it fit perfectly.

I was thinking of doing the same. I have a intex pump and sand filter and i think my current gauge tops out at 60psi. Really? Why so high? Im gonna get the 30psi one from TFTestkits. I dont think my filter has pressure over 30psi. Atleast i hope not!
