Grayline

Since its founding in 1966, Grayline has been a leader in manufacturing flexible polymer tubing. Initially rooted in the wiring harness and electrical tubing markets, Grayline has since diversified its product offerings to include fluid transfer products such as chemical-resistant tubing, food and beverage tubing, medical tubing, fuel and oil-resistant tubing, and pneumatic and hydraulic tubing. 

Grayline's flexible tubing products, available in both heat shrinkable and non-heat shrinkable variants, are versatile solutions used to bundle objects, protect items from abrasion or environmental factors, thermally insulate components, enhance the appearance of articles, and provide color-coding, identification, or marking.

Grayline boasts a portfolio of over 100 different types of tubing products in a variety of sizes and colors, many of which meet stringent industry standards such as UL/CSA, ASTM, AMS, Automotive, Military, EU Directives, USP, NSF, and FDA. As a manufacturer, Grayline offers extensive custom services, including color matching, specially formulated materials, individualized diameters and wall thicknesses, cut-to-length parts, in-line printing, hot stamping, and heat forming.
