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.

Descriptions
Tylok tube fittings are fully interchangeable with Swagelok & Parker A-Lok and Parker CPI™. A leak-proof seal is obtained through proper ferrule action as the ferrules are tightened onto the tubing via axial thrust provided by the nut. The ferrule provides a leak-proof seal when the nut and ferrule are properly tightened the specified number of turns. Tylok fittings are manufactured in stainless steel, brass and carbon steel.
Our American-made tube fittings are used in instrumentation tubing systems in all process industries, including oil and gas, pulp and paper, steel manufacturing and energy. Our elbow tube fittings come in multiple configurations including unions, 45° angles, female NPT, Male NPT, position able, butt weld & socket weld.
