Running a
successful business
since
1978
R-K Industries was founded in 1978 by visionary technocrats in Ontario, California, where
we’ve proudly remained ever since. From the outset, our mission was clear: to push the
boundaries of scientific innovation by developing high-precision thermoplastic valves—and we
did just that. Our early breakthroughs led to patented valve designs that set new industry
standards and laid the foundation for our future growth.
Initially serving the scientific research sector, we quickly earned a reputation for
engineering excellence. But it wasn’t long before we identified a critical industry
need—thermoplastic valves capable of handling interactive and highly corrosive fluids. At
the time, quality solutions in this space were scarce. Rising to the challenge, our team
combined deep technical expertise with relentless innovation to develop a line of advanced,
corrosion-resistant valves tailored for harsh chemical environments.
Our patented products and customer-driven approach sparked rapid expansion, allowing us to
serve an increasingly diverse clientele across multiple industries. Today, R-K Industries
continues to lead with a growing portfolio of specialized valve solutions—engineered to
perform, built to last, and trusted by professionals worldwide.
A key part of our success lies in our strong partnerships with industry-leading
distributors, who share our commitment to reliability, technical support, and customer
satisfaction. Through these valued alliances, we ensure that R-K products are available
where and when they’re needed—backed by knowledgeable partners who understand the critical
nature of fluid control solutions.
