My nitrogen regulator is behaving strangely

[Coastarine]

The pressure keeps creeping up. I set it for about 16psi, the gas equalizes and the needle stops, but by 24 hours later it will be in the mid 20's. It isn't causing any problems with the pour or anything, but I'd still like to make this stop. Nitrogen Gas Regulator Double Gauge Draft Beer Tank - Regulators

This is the second one they sent me that is doing this. I exchanged the first one because of it. Now I'm wondering if the problem isn't the regulator, if it is somehow me, or maybe I should just return this one and buy from somewhere else.

sounds like a part of your regulator is sticking. there's a needle like apparatus connected to a diaphragm in there that may be the culprit. I lubed mine with vaseline or something, it works like a charm.
