## Description

Water Pressure test gauge for use with reverse osmosis systems, aquarium discuss marine systems and all water filter systems. Using a pressure gauge with your reverse osmosis system can be a great addition to your system as most problems that occur with reverse osmosis systems can relate to your water pressure. Pressure Gauge Pack Includes: 1 x Pressure Gauge with ¼" male connection 1 x ¼" female to ¼" push fit 1 x ¼" Stem to ¼" push fit to ¼" push fit T

Review: works perfectly - order two of these to monitor water pressure before and after my softener\filters. I tested the gauges and they were within 1-2psi of a known accurate gauge. some reviewers complained about these leaking at the connector. I did not have this issue. over-tightening of plastic connector is a common mistake for most DYI`ers. as with ANY plumbing connection. over-tightening will NOT stop a leak. in fact it will make it worse and even break the connection. connectors like the included one should be hand tightened and then just another 1/4 turn with a small wrench. what I did with this connector is to just put a small O-ring into the connector (it should have included one but unfortunately does not). I then used RectorThread #5 pipe thread sealant instead of PTFE tape. PTFE tape is technically not meant to SEAL pipe threads. it is meant to lubricate NPT threads for assembly. some sealing occurs as an after-effect but it is not its primary function. doing this sealed the connector properly and i have NO leaks. other users complained that the gauge is is not fully filled with Glycerin. this is by design. all of these types of gauges have a small air bubble in them. some of the top of the line high pressure fuel gauges i use in my race car have this bubble. now, if it all leaks out or is only half full then it is defective and should be returned. in any case, these gauges look great and perform perfectly.
Review: Great for Reverse Osmosis Booster Pump - I installed a booster pump on my reverse osmosis system and I was unsure what the actual pressure of the system was, other than just checking the faucet water flow - which was higher but I was unsure if it was at full potential. With the addition of this gauge I was able to monitor the pressure on the gauge and increase the upper limit on my high pressure switch to get more water flow without over-pressurizing the system. The quality seems real good and worked real well for this application.

### ⭐⭐⭐⭐ Works ok but there's some leakage that I fixed
*by E***O on July 11, 2024*

This water pressure gauge has worked fine for me; there was some leakage from the thread/connector. I fixed the leakage using the provided o-ring and also used teflon tape. I wrapped the male thread 5 times (360 degrees each time). I hand-tightened it until it couldn't turn anymore, then I used a wrench and tightened it 1/4 turn. This was the solution to the leakage. I increased/decreased my booster pump's pressure all the way up to 120 PSI, ran it for 30 minutes on a misting system kit and there was no leakage. The mist was almost like fog by the way (I didn't get soaked in water).
