Review on LDR 020 9645 4 Inch Pressure: Improved SEO-Friendly Product Name by Walter Martin

I was disappointed with the LDR 020 9645 gauge. As others have pointed out, the red arm is so loose that it's unreliable. The main problem is water leakage as others have pointed out. I am a retired refinery engineer with extensive experience of high pressure fluids, piping components, seals etc. This gauge has a design and/or manufacturing defect. When I first installed it on a faucet, it leaked significantly at the point where the gauge connected to the faucet. I thought the gasket might be bad so I replaced it but it leaked just as bad. Then I used 2 gaskets and there was no leakage. It appears that the threads on the gauge fully engage the male threads of the faucet before the faucet is fully seated on the gasket. The sensor showed 65# which is what I expected. I don't have another sensor to compare, but I have no reason to doubt the accuracy of the measurement.
