Our Story
Founded in 1966, Grayline has evolved from a small family business into an industry leader in tubing and heat shrink products. Headquartered in Waukesha, Wisconsin, our state-of-the-art facilities now produce an impressive 150 miles of tubing daily. We’ve expanded from our roots in the wiring harness and electrical tubing markets to include a wide range of fluid transfer products such as chemical-resistant tubing, food & beverage tubing, medical tubing, fuel & oil resistant tubing, and pneumatic & hydraulic tubing.
