Quality starts at home, which is why all Harris 450 industrial regulators are made in the USA. We use precision machining and robotic equipment to achieve tolerance levels others simply can’t match. Our regulators are 100% tested, 100% of the time, for both workmanship and performance. You can be confident that Harris doesn’t just talk about quality – we back you up with quality with our 3-year exclusive premium warranty.

Easy-to-use Design
We have been making industrial regulators for over a century and it shows. The Harris Model 450 features large 2 ½” brass dual scale gauges that feature both PSI and BAR pressure scales to make it easy to read and set your required delivery pressure. The oversize pressure adjusting screw requires less user input when adjusting allowing you to reach those higher pressures. When a tough job is on the line, a new design won’t help much if it can’t be read and adjusted in the field, the Model 450 designed and perfected on the job.
