Do any of you use glycerin filled pressure gauges?

I've been thinking of replacing some of my gauges due to age, corrosion, and dents/damage. I found some cheap grade b dry gauges for around $8, but I'm wondering if it is worth it to upgrade to Grade A (accuracy 1.5%) glycerin filled gauges. The only thing is I've got a lot of gauges, so I may try one or two at first, and see how I like them. I'd appreciate any input though!

 

This is the one I am looking at: https://www.amazon.c...D3CRV8834A1XJFD

 

I like it because of the accuracy, as well as the stainless casing. I also found some plastic cased ones that are 1.6% accurate, and Amazon sells a 10 pack for just over $100 dollars, which would cover most of the gauges I need to change out, I just don't know how durable the plastic casing would be. I tend to think the stainless case is worth the $4 extra dollars per gauge if I am going to go this route anyway.

 

This is the link to the 10 pack of the ABS: https://www.amazon.c...m_cd_al_qh_dp_t

When I was a mechanic, I bought a couple for my AC gauge set because the high pressure side would shake the needle erratically making it hard to read. The glycerin dampened the vibration. That's the only reason I would buy filled over dry. Over the years my glycerin has slowly seeped and collected dirt/grime and had discolored. My gauges look like crap.

Hmmmmm, I definitely wouldn't want them to leak.

 

I liked that they were supposed to help lubricate and prevent corrosion, because I have had issues with corrosion in the past on the gauges on secondary regulators in my keezer at the time.

 

I may just get one or two of the stainless to start with, and see how those go then. I definitely want the accuracy, as I think some of my gauges are off. I was actually thinking of building a small gadget to compare gauges and see which ones were more off than others (a stainless Tee with a ball lock gas fitting on one end, and a gauge on each of the other sides to compare, maybe even a cross to compare three gauges at a time).

One of my gauges is filled and that is just because we had it on hand to replace the broken one. I don't really see the need since the needles should not really be bouncing around.

Here is a good dry gauge. It has a screw to let you zero it instead of a peg at zero. Much more accurate over the long haul.

only pain for that one may be how it mounts, back center.  I do like the adjustment option though.

Whoops, missed the mounting on that. It's their P9S series. Think this is the correct one. 1/4 npt bottom mount. Check thread size to your regulator though.

2 more of the SS bucket ones I posted before.  one more 7 and one 14.  I will modify them to accept tri-clamp fittings and have a thermowell.

I plan on purchasing a 14g. Wish it was 15g but I will take it and silver solder the TC fitting like you did so I can continue to use my sanke caps.

With that said, filled gauges are cool but not necessary. Just like a lot of my brew gear. Cool factor ya know!

I think it was a 1" conduit knockout punch worked perfect for the hole, I will double check though.

That is definitely an interesting option, I've never had a pressure gauge that I could reset. Its accuracy is only a bit less than that of the glycerin filled one. What I may do is get two of each, and do some tests/comparisons, then go from there.

 

Thanks for the links!

Well, I decided to go ahead and get one of each. I will build a little test setup, but I won't use a ball lock connector, I'm just going to use my John Guest fittings and connect it directly to one of my gas lines, varying the pressure, and checking it against the gauge that is on the regulator itself.
