For fifty years, Rust Automation & Controls has connected the best automation, valve, and instrumentation lines with the engineers, plants, and buyers who depend on them — backed by reps who answer the phone and expertise you can't get from a catalog.
Rust is a manufacturers' representative and a distributor — which means we're on the plant floor and in the engineering conversation, not just shipping boxes.
That's the difference fifty years buys: we know the equipment, the process, and the people. When a line goes down or a project needs spec'ing, you get someone who's solved it before — and who'll stand behind the answer.
Application engineering, product selection, and on-site help — plus tools that take the guesswork out of sizing and selection.

Each line gets a real page — what it is, where it fits, datasheets, and a direct path to a quote or a rep. Built to be genuinely useful (and findable in search), not a logo wall.
Practical tools for the people who do the work — free, fast, and built from fifty years of knowing what engineers and buyers actually need. This is just the start.
Valve sizing (Cv), pressure drop, unit conversions, and more — the math you'd otherwise do by hand, right in the browser.
Find the Rust-supported equivalent for a competitor or legacy part number in seconds.
Build a valid part number across 195,000+ instruments and drop it straight into a quote.
Spec sheets, manuals, and drawings for every line — one searchable place, always current.
See where your quotes and orders stand without making a call. Account holders only.
Tell us the tool that would save your team an afternoon — we build the ones people ask for.
Since 1976, the same name has been over the door. We've grown by doing right by the engineers, plants, and manufacturers who trust us — and by hiring people who stay. That continuity is the product.
An account isn't a form for the sake of it — it's how we tailor Rust to your plant and your role, and how we keep the relationship personal even as we grow.
Takes a minute. A rep follows up within one business day.
RegisterWe'll never sell your information. You control what we send.
Send a parts list, a print, or just the problem. A real engineer reads it and gets you a real answer — usually the same day.
