• 0-100 PSI READING 
• This liquid-filled pressure gauge and psi gauge gives accurate readings in the range of 0-100 psi!
• WATER PRESSURE TEST GAUGE
• This gauge can be used to test water pressure, whether in your home, irrigation system, or anywhere else!
• SCHRADER VALVE COMPATIBLE
• This gauge reads from Schrader valves, the same valves used with tire pressure gauge(s), tire gauge(s), and air pressure gauge(s)!
• RELIABLE
• Unlike digital tire pressure gauge(s), this does not feature any electronic or digital components and is built to last!
• VERSATILE
• Can be used as an air gauge, water gauge, water pressure tester, RO pressure gauge, or pool pressure gauge!

Instead of having to buy, install, and maintain multiple pressure
gauges; use these quick connects to just keep one and quickly test
your pressure in many different places. These really help in large
filtration systems where you can check before and after the filters to let you know if they need to be cleaned yet or not. The kit includes an oil-filled (so you can use at different angles) 0-100 psi gauge and you can also order the quick connects separately.
