Review on 🌊 Stainless Steel Malida Water Pressure Gauge for Aquarium Meter & Reverse Osmosis System Pump, 0-1.6MPa / 0-220psi, 1/4" Size by Melissa Flores

Requires lots of thread tape to prevent leaks. Otherwise it would have been a five star rating. Good quality sensor, good connectors included. If the seller wants the threads to be mismatched to save money, he should let him know. I already had one of these, just added two more at different stages in my water filtration and reverse osmosis system. It's a good buy, but leaks are frustrating until you sort out the tape and mismatched threads.
