History of Tylok
In the mid-1940s, Cullen Crawford developed and patented the original flare-less fitting (nut & double ferrule system), making it easier and more efficient to make tubing connections. Based on this innovation, he founded the Crawford Fitting Company, creating an industry for compression fittings. Now, Tylok has been manufacturing its products in the USA for 69 years. We are continuing to innovate and provide quality-driven products to our customers.
