Waterproof pressure sensor was a good fit

I was replacing an older sensor and needed something that could handle a wet environment. This one looked like a good fit, so I checked the thread size and pressure range before ordering. Got it installed and wired up without much trouble. Checked the readings a few times, and everything looked good. Pretty happy with the replacement so far.
